Rising from the blue waters off the northeastern coast of Taiwan, Guishan Island — often called Turtle Island — is one of the country’s most fascinating natural landmarks. Shaped like a giant turtle resting in the sea, this volcanic island blends dramatic cliffs, steaming fumaroles, cultural legends, and wildlife encounters into one unforgettable destination. Though small in size, it offers a surprisingly rich experience for travelers looking beyond Taiwan’s cities.
Below are the key highlights and places that make Guishan Island a must-visit.
1. Guishan Island Coastal Trail
Walking the coastal trail is the best way to appreciate the island’s rugged beauty. The path winds through lush vegetation, volcanic rock formations, and sweeping ocean viewpoints. Along the way, you can hear waves crashing against the cliffs while seabirds glide overhead.
Bold ocean panoramas, fresh sea breezes, and the scent of coastal forest combine to create a peaceful yet dramatic atmosphere. This trail also reveals how volcanic activity shaped the island’s terrain, from steep slopes to unusual rock patterns.
2. Turtle Head Lookout
One of the most famous viewpoints on the island, Turtle Head Lookout, sits near the elevated section that forms the “head” of the turtle shape. From here, visitors can enjoy wide-angle views of the Pacific waters, fishing boats drifting below, and the mainland coastline in the distance.
This spot is particularly magical during clear mornings when sunlight illuminates the surrounding sea in shades of turquoise and deep blue. Photographers often consider it the best place on the island for panoramic shots.
3. Volcanic Steam Vents
Guishan Island is not just scenic — it is geologically alive. Near the shoreline, steam vents release warm vapor and sulfuric gases from underground volcanic activity. These fumaroles remind visitors that the island was formed by powerful geological forces and still holds heat beneath its surface.
The sight of steam rising against the ocean backdrop is surreal, and the faint smell of sulfur adds to the sense of stepping into a living volcanic landscape.
4. Military Tunnel Remains
For decades, Guishan Island served as a strategic military post. Remnants of this period remain visible in the form of tunnels carved into the rock. Exploring these tunnels offers a glimpse into Taiwan’s modern history and the island’s former restricted status.
Today, these tunnels provide both historical interest and shelter from the sun, making them a unique part of the island’s story.
5. Lighthouse and Coastal Plateau
The lighthouse area sits on a plateau overlooking the ocean, offering calm and open scenery. The view from here contrasts sharply with the cliffs elsewhere, giving visitors a chance to see the island’s gentler side.
The combination of grassy slopes, ocean horizon, and distant mainland views makes this area ideal for quiet reflection and photography.
6. Dolphin and Whale Watching Waters
The waters surrounding the island are famous for marine life sightings. Boats traveling from Yilan County often spot dolphins, and during certain seasons, whales can also be seen migrating through the region.
This makes the journey to the island just as exciting as the destination itself, especially for nature lovers and wildlife enthusiasts.
7. Abandoned Village Site
Guishan Island once had a small fishing community. Though residents relocated years ago, traces of the old settlement remain. Walking through this area reveals how people once lived in isolation, surrounded by sea and volcano.
The quiet ruins and empty paths create a reflective mood, reminding visitors how nature often reclaims human settlements over time.
8. Volcanic Sulfur Springs Shoreline
One of the island’s most unusual features is its sulfur springs along the coast, where mineral-rich water meets the sea. The yellow-tinted rocks and steaming shoreline create an almost otherworldly scene.
These springs highlight the island’s volcanic origin and make Guishan feel like a natural laboratory of geological forces.
Final Thoughts on Visiting Guishan Island
Guishan Island is more than a scenic boat excursion — it’s a journey into Taiwan’s geological past, cultural legends, and coastal ecosystems. From volcanic vents to ocean wildlife and historic remnants, every part of the island tells a different story.
Because access to the island is regulated to protect its fragile environment, visiting here feels exclusive and meaningful. For travelers seeking nature, history, and unique landscapes in one place, Guishan Island stands out as one of Taiwan’s most rewarding hidden gems.
