Green Island Taiwan Travel Guide 2026: Diving, Hot Springs + How to Get There
Green Island Taiwan is one of Southeast Asia’s most underrated island escapes. This 16 sq km volcanic island sits 33 km off Taiwan’s southeast coast, yet it packs three things almost no other island on the planet can claim at once: a saltwater hot spring that ranks among only three of its kind in the world, a 30-site scuba diving network with visibility up to 30 meters, and a sobering political history that gives the experience real depth. If you’re planning a Taiwan trip in 2026, this green island taiwan guide covers every practical detail, from the 50-minute ferry to scooter rental prices and what to do after dark.
Key Takeaways
Green Island (Lyudao / 綠島) lies 33 km off Taitung; the ferry takes 50 minutes and costs around NT$340-500 (~US$10-15) each way
Zhaori Hot Springs is one of only 3 saltwater hot springs in the world — admission NT$200 (~US$6), open 24 hours, best visited at night (Taiwan Tourism Bureau, 2026)
30+ dive sites with 20-30m visibility; a day dive tour runs NT$1,500-2,500 (~US$45-75)
Scooter rental (~NT$500-700/day) is the only practical way to circle the 17 km coastal road
Bring cash from Taitung — ATMs on Green Island rarely accept foreign cards

What Makes Green Island Taiwan Worth Visiting?
Green Island Taiwan earns its reputation on a rare combination: world-class diving, a genuine geological oddity in the Zhaori Hot Springs, and a layer of 20th-century history that most Pacific island getaways simply can’t offer. Taiwan Tourism Bureau data shows the island attracts over 300,000 visitors per year despite having a permanent population of only around 3,000 (Taiwan Tourism Bureau, 2026). That ratio — 100 visitors per resident each year — tells you the experience is intensely concentrated for its size.
What separates Green Island from better-known Asian dive destinations like Koh Tao or the Gili Islands is the geological backstory. The island sits directly on the Philippine Sea Plate boundary, which is why geothermal activity is strong enough to push 93°C saltwater to the surface at Zhaori. That same tectonic energy built the rocky black coastline that now shelters coral gardens rich enough to support green sea turtles, reef sharks, and nudibranchs within a 10-minute boat ride from shore. The history layer — a former political prison that held democracy activists under martial law — makes Green Island one of the few dive destinations where you can snorkel with sea turtles in the morning and visit a UNESCO-nominated human rights site in the afternoon.
At 16 sq km, the whole island can be circled by scooter in under an hour. That compactness is a feature, not a limitation. You’re never more than 20 minutes from your guesthouse, the hot springs, or the water entry points.

How to Get to Green Island Taiwan
The most practical route to Green Island starts in Taitung City on Taiwan’s east coast. Two transport options connect Taitung to the island: a 50-minute ferry from Fugang Fishing Harbor or a 15-minute propeller plane from Taitung Airport. The ferry runs multiple departures daily and costs NT$340-500 (~US$10-15) each way; the plane is faster but costs roughly three to four times as much and has limited seat availability (Green Island Ferry Service, 2026).
Ferry from Fugang Fishing Harbor (Recommended)
Fugang Fishing Harbor sits about 25 km south of Taitung City. Taxis from Taitung train station to the harbor cost around NT$350-400 one way, or you can rent a scooter and ride down the scenic Highway 11. Ferries are operated by two main companies: Ding Tai Lun (鼎泰輪) and Haijing Ferry. Departures run multiple times daily, with the most reliable morning departures at 7:30am and 10:30am. Book tickets at least a day ahead in peak season (April-October).
The crossing takes 50 minutes in calm conditions. Be aware: the Taiwan Strait can be choppy, and operators cancel services with little warning during rough weather. If you’re prone to seasickness, take medication before boarding.
Propeller Plane from Taitung Airport
Uni Air operates turboprop flights from Taitung Airport to Green Island Airport. The 15-minute flight costs approximately NT$1,500-2,500 (~US$45-75) one way and fills quickly. Book directly through Uni Air’s website well in advance, especially for weekend and holiday travel.
Getting to Taitung First
Taitung is well connected from Taipei. The Puyuma Express or Taroko Express trains on Taiwan Railways (TRA) run Taipei to Taitung in about 2 hours 30 minutes, with tickets from NT$843 (~US$25) (TRA Taiwan Railways, 2026). Book at least 3-5 days ahead for weekend trips.
We’ve found the overnight option — arriving in Taitung the night before and catching the 7:30am ferry — works much better than racing to the harbor from Taipei the same morning. The ferry dock area offers limited breakfast options, so eat in Taitung before you go.

Scuba Diving and Snorkeling at Green Island Taiwan
Green Island Taiwan is consistently ranked among the top 10 dive destinations in Asia, and the numbers justify that claim. The island has over 30 marked dive sites with average visibility of 20-30 meters, water temperatures of 24-28°C year-round, and documented populations of green sea turtles at sites like Big Mushroom Rock (大香菇) and the Sleeping Diver (Divemagazine Asia, 2025). A day dive tour with two tank dives runs NT$1,500-2,500 (~US$45-75) depending on the operator and whether gear rental is included.
Best Dive Sites on Green Island
Big Mushroom Rock (大香菇): The island’s signature site. A 12-meter volcanic pinnacle surrounded by hard coral and almost always visited by green sea turtles. Best for intermediate divers and up, 8-15m depth.
Sleeping Diver (睡美人): Named for a rock formation that resembles a reclining figure. Strong current brings pelagic fish — trevally, barracuda, and occasionally reef sharks. Suitable for experienced divers.
Shilang (石朗): The most popular snorkeling site, accessible directly from shore. Shallow (3-8m) and calm, with dense table coral and clownfish. Snorkel gear rentals available on the beach for around NT$200-300.
Nuclear Reactor (核電廠): No, it’s not actually a nuclear plant — the name comes from the circular rock formation. Good for night diving; nudibranchs and moray eels are common after dark.
One detail most generic diving guides skip: Green Island’s tidal timing matters more than at many Pacific destinations. The combination of current direction and visibility is most favorable 2-3 hours after sunrise and 1-2 hours before sunset. Booking a dive tour that launches around 7:30am means you hit the clearest water before the afternoon thermal chop builds. Ask any local operator about “chao shui” (tide water) timing before locking in your slots.
Independent snorkeling is easy at Shilang Beach and Zhaorixing Beach (朝日溫泉沙灘). Entry is free, gear rentals cost NT$200-300 from beachside shops, and no boat is required. The coral starts within 20 meters of the shoreline at Shilang. Currents at these sites are mild outside typhoon season.

Zhaori Hot Springs: The Saltwater Hot Spring Experience
Zhaori Hot Springs (朝日溫泉) is one of only three saltwater hot springs in the world — the others are in Japan’s Kagoshima Prefecture and Tuscany’s Saturnia. Geothermal activity forces seawater through heated volcanic rock, producing a naturally saline brine that reaches 93°C at the source before cooling to around 40°C in the outdoor pool system (Taiwan Tourism Bureau, 2026). Admission is NT$200 (~US$6) and the facility operates 24 hours a day.
The pools are set directly on a clifftop above the Pacific Ocean. Three tiers of pools offer slightly different temperatures (roughly 37°C, 40°C, and 43°C). The setting — black volcanic rock, open ocean horizon, often a sky full of stars — is genuinely spectacular. The experience is dramatically better at night, between 9pm and midnight, when day-trippers are gone and the temperature contrast between the warm pools and cool ocean air becomes most enjoyable.
We’ve visited Zhaori on both a day-trip schedule and as overnight guests, and the gap in experience is significant. At 2pm on a Saturday in July, the pools are crowded enough that finding a spot requires waiting. At 10pm on the same day, the same pools hold perhaps a dozen people with the Milky Way visible overhead. If you’re doing Green Island as a day trip and the ferry timing allows, catch the last boat home at 4pm or 5pm and skip Zhaori entirely — it’s wasted in daytime crowds. Commit to an overnight stay and make the hot springs your last activity before bed.
Practical Notes for Zhaori
Swimwear is required; no street clothes in the pools.
Towels and lockers are available on-site for a small additional fee.
The facility has a basic changing room and outdoor showers.
From Naniao Village (the main cluster of guesthouses), Zhaori is about 2.5 km on the coastal road — a 10-minute scooter ride.

Where to Stay on Green Island
Accommodation on Green Island ranges from basic family guesthouses (民宿, minsu) to a handful of mid-range resort-style properties. The main cluster sits in and around Naniao Village (南寮村) near the ferry dock. Expect to pay NT$800-2,000 (~US$25-60) per night for a clean, air-conditioned double room at a budget guesthouse, and NT$2,500-5,000 (~US$75-150) for a mid-range property with a pool or ocean view.
Most guesthouses on Green Island don’t appear on international booking platforms; they’re booked through LINE messages or local Taiwanese booking apps. However, a growing number now list on Booking.com and Agoda, particularly the newer mid-range properties.
Location near Naniao Village. This puts you closest to scooter rental shops, dive operators, and the ferry dock. Most of the island’s restaurants are also here.
Scooter rental included. Many guesthouses include a scooter or e-scooter in the room rate. This is worth more than it looks — it saves NT$500-700/day and avoids rental queue time in the morning.
Air conditioning. Non-negotiable from May through October; the island runs hot and humid.
One booking detail most visitors miss: Green Island guesthouses fill weeks in advance for summer weekends (July-August) and national holidays (especially Dragon Boat Festival in June and Mid-Autumn Festival in September). The island has a limited total bed count, and when Taiwanese mainlanders descend for long weekends, every bed within walking distance of the ferry dock books solid. If your dates are flexible, Tuesday through Thursday visits in April, May, or October offer the best combination of availability, price, and weather.
Getting Around Green Island
Scooter rental is the standard — and essentially the only practical — way to get around Green Island. The coastal road circles the entire island in 17 km. A standard 125cc scooter rents for NT$500-700 per day from shops concentrated near the Naniao Village ferry dock. Electric scooters are available from some operators for roughly the same price and are fine for the flat sections of the circuit, though the hill climbs to viewpoints like Guanyin Cave benefit from a petrol model.
Rental shops typically require a valid driver’s license. Taiwan does not accept most foreign licenses for scooters above 50cc without a local endorsement, so many visitors rent 50cc scooters or e-bikes instead. Check your license class before arriving.
The 17 km Coastal Road Circuit
The full island circuit is one of the great short coastal drives in Asia. Starting from Naniao Village and going clockwise, you’ll pass:
Shilang Snorkeling Area (3 km from dock)
Green Island Lighthouse (lighthouse; photo stop, 5 km)
Green Island Human Rights Memorial Park (7 km; plan 45-60 minutes)
Lyudao Farm Beach (9 km; swimming)
Guanyin Cave (12 km; natural cave with a coral statue)
Zhaori Hot Springs (14.5 km)
Back to Naniao Village (17 km)
The full circuit with stops takes 3-4 hours at a relaxed pace. Fuel up your scooter before leaving the village — there’s only one petrol station on the island.

Best Time to Visit Green Island Taiwan
April through October is the main visitor season, when calm seas allow reliable ferry service and water temperatures sit at their warmest for diving. The best windows within that range are April-May and September-October, when crowds are manageable, accommodation is available, and the weather is dry without the full summer heat. June through August is peak season: school holidays push visitor numbers up sharply, accommodation books weeks ahead, and ferry services occasionally cancel due to summer typhoons.
Typhoon Season (June to September)
Taiwan’s typhoon season overlaps directly with peak travel season. A direct hit on the Taitung coast can ground ferries for 3-5 days and make scooter travel on the island’s exposed coastal road dangerous. The Taiwan Central Weather Administration (Taiwan CWA, 2026) issues typhoon warnings 24-72 hours in advance. If a typhoon watch is posted, assume ferries will cancel.

For diving specifically, March through May is the sweet spot: post-monsoon clarity gives the best visibility of the year, jellyfish numbers are low, and water temperature is already above 24°C without the exhausting summer heat above water.
Green Island Human Rights Memorial Park
Green Island’s history as a place of natural beauty runs parallel to a darker chapter. From 1951 to 1987, the island served as a political detention center under Taiwan’s martial law period — the longest martial law period of any country in the 20th century, lasting 38 years (Taiwan National Human Rights Museum, 2026). At its peak, the Oasis Villa Prison held over 2,000 political prisoners, many of them intellectuals, journalists, and democracy activists.
The Green Island Human Rights Memorial Park now preserves the former prison complex. A circuit walk of the preserved buildings, interrogation rooms, and solitary confinement cells takes 45-60 minutes. The inscriptions on the “Declaration of Human Rights Monument” — carved by former prisoners — are among the most affecting things you’ll read on any island vacation in Asia.
Most Western travel guides treat this site as an optional cultural footnote. We’d argue it’s essential context. Taiwan’s democracy today — ranked among the freest in Asia — was bought partly by the people who were imprisoned on this island. Spending an hour at the memorial park, even amid a diving and hot-spring-focused trip, changes how you understand the place you’re staying.
Admission to the memorial park is free. Opening hours are 8:30am-5:30pm daily.

Green Island Taiwan FAQ
Is Green Island Taiwan worth visiting for non-divers?
Yes, absolutely. Even without scuba certification, the Zhaori Hot Springs alone justify the trip for most visitors. The snorkeling at Shilang Beach is excellent for beginners (shallow, calm, gear rental on-site). The island circuit by scooter is one of the best coastal rides in Taiwan. The Human Rights Memorial Park adds cultural depth. Most visitors who arrive without dive experience still rate Green Island among the highlights of their Taiwan trip (Taiwan Tourism Bureau visitor surveys, 2025).
How much does a Green Island trip cost?
Budget roughly US$60-90 per day for a comfortable 2-night stay. Ferry tickets cost US$10-15 each way. A clean guesthouse runs US$25-60/night. Scooter rental is US$15-20/day. Zhaori Hot Springs is US$6 admission. Meals from local restaurants cost US$4-8 per dish. A guided dive tour adds US$45-75. Total for 2 nights including diving once: approximately US$250-350 per person (Taiwan Tourism Bureau, 2026).
Do I need a visa to visit Green Island as a foreign tourist?
Green Island is part of Taiwan, so standard Taiwan entry requirements apply. Most Western passport holders (US, EU, UK, Australia, Canada) receive visa-free entry to Taiwan for 90 days. Citizens of other countries should check Taiwan BOCA (Bureau of Consular Affairs) visa requirements before travel (Taiwan BOCA, 2026).
Can I visit Green Island as a day trip from Taitung?
Yes, but with caveats. The 7:30am ferry gets you to Green Island by 8:20am, and the last return ferry typically departs around 4:00-4:30pm, giving you roughly 7-8 hours on the island. That’s enough for the coastal scooter circuit, snorkeling at Shilang, lunch, and a visit to the memorial park. You won’t have time for the hot springs at their best (night visit recommended) or a dive tour. An overnight stay is strongly preferred if your schedule allows.
Is there mobile data coverage on Green Island?
Yes. Taiwan’s major carriers (Chunghwa Telecom, Taiwan Mobile, Far EasTone) provide 4G coverage on most of the island, with some gaps on the hillier interior trails. A Taiwan eSIM purchased before arrival keeps you connected throughout your trip without swapping physical SIM cards.
Green Island Taiwan delivers a genuinely rare combination. There are dozens of dive islands in Asia. There are hundreds of hot spring resorts. But there’s only one place in the world where you can snorkel with green sea turtles over volcanic reef in the morning, soak in one of the planet’s three saltwater hot springs under the stars at night, and spend an afternoon reading the inscriptions left by political prisoners on the walls of a former martial law detention center. That is a concentrated, distinctive experience.
The practical summary: fly or train to Taitung, catch the 7:30am ferry to Fugang, rent a scooter at the dock, do the coastal circuit clockwise to catch the memorial park and lighthouse before lunch, dive or snorkel in the afternoon, and hit Zhaori Hot Springs after 9pm. Stay two nights if you can. Bring cash. Book accommodation in advance for any summer weekend.
