The Tonghou Traversing Trail (桶後越嶺步道) is one of Taiwan’s most authentic, scenic, and historically rich hiking routes — a true adventure that blends nature, culture, and rugged outdoor experience. Unlike crowded tourist trails like Taroko Gorge or Alishan, Tonghou remains a hidden gem for hikers seeking wilderness, river landscapes, and forest‑lined pathways deep within northern Taiwan’s mountains.
Stretching roughly 6.8 km as the core trail between Wulai and Jiaoxi (with the forest road approach extending the total trek closer to 20 km depending on route choices), this trail offers a blend of moderate terrain, river views, and lush jungle immersion.
Whether you are an experienced trekker or a curious traveler who loves discovering hidden landscapes, this complete 2026 guide will tell you everything you need to know about the Tonghou Traversing Trail.
Introduction to Tonghou Traversing Trail
The Tonghou Traversing Trail is an ancient pathway cutting across the foothills of the Snow Mountain Range, linking the mountainous district of Wulai in New Taipei City to Jiaoxi Township in Yilan County.
In its current form, the trail is celebrated for its serene river scenery, broadleaf jungle canopy, dramatic mountain ridges, and as a journey through the historical heartbeat of Taiwan’s indigenous geography. That’s because the trail began as a footpath long used by the Atayal indigenous people before later being expanded during the Japanese colonial era.
Today, it’s a popular eco‑tourism destination celebrated for moderate hiking — offering both challenge and accessibility — without the overcrowding found on Taiwan’s better‑known routes.
Historical & Cultural Significance
Origins with the Atayal People
Long before modern roads and trails, the region’s indigenous Atayal people used this pathway as a migratory route for trade, hunting, and connecting inland valleys with coastal plains.
These paths weren’t merely trails — they were the lifelines for mountain communities, enabling cultural exchange and survival across Taiwan’s rugged interior.
Japanese Colonial Expansion
During the early 20th century under Japanese colonial rule, the trail was formalized into a forest road to facilitate timber operations, management of indigenous communities, and logging logistics.
This expansion marked an important transition from indigenous footpath to a structured trail system that still defines much of the route hikers experience today.
Modern Preservation and Tourism
After damage from major typhoons (notably Typhoon Soudelor in 2015), the trail underwent restoration efforts, with rebuilt sections and high traverse detours allowing safe passage while preserving historical paths.
Scenic Highlights Along the Trail
Walking the Tonghou Traversing Trail is like moving through a living landscape painting — lush valleys, cool streams, and viewpoints that capture both mountain grandeur and forest intimacy.
Lush Forests and Bamboo Groves
From the trailhead to the river section, you’ll pass through dense jungle dominated by subtropical flora — including towering broadleaf trees, giant ferns, and thick bamboo stands. This creates a natural jungle canopy that cools the trail and provides habitat for diverse bird species.
Crystal Rivers and Water Features
Much of the trail follows the course of the Tonghou River, offering opportunities for refreshing riverside breaks or scenic picnic spots. Look for minor waterfalls and clear stream pools — perfect for short dips on hot summer days.
Scenic Ridges and Vista Views
While the forest feels intimate and enclosed, certain points reveal expansive views of Yilan’s plains and distant mountains. On clear days, you may even glimpse Turtle Island (a volcanic islet off the Yilan coast) on the horizon.
Photogenic Terrain and Natural Features
The trail’s bridges, metal stair sections, and river‑skirting paths make excellent spots for photography, from dramatic cliffside platforms to secluded riverbanks.
Best Time to Hike Tonghou Traversing Trail
Seasonality plays a big role in your hiking experience:
Spring (March – May)
Spring brings mild temperatures and reduced rainfall compared to summer, making it one of the top choices for hiking comfort and trail safety.
Summer (June – August)
Summer is warm and humid, but river sections provide natural cooling spots. Be aware that short afternoon storms are common, and trail runoff can make some sections more slippery.
Autumn (Late Sept – Nov)
Autumn mirrors the charm of spring — stable weather, breezy conditions, and lush greenery. It’s ideal for medium‑length hikes without excessive heat.
Winter
For adventurous hikers, winter yields cool, misty atmospheres and dramatic light on forest floors, but caution is needed as some muddy sections may become slick.
Trail Details Every Hiker Should Know
Total Distance and Sections
The official Tonghou Traversing Trail itself is 6.8 km one‑way, but most hikers experience this route in three distinct walking sections:
- Forest Road Approach (~12–13 km): From the access point along Tonghou Forest Road to the official trailhead.
- Main Trail (6.8 km): The core historic and scenic section.
- Final Road to Jiaoxi (~3 km): A compact double‑track road leading to pick‑up points.
This brings the total hiking experience (forest approach + traversing trail + exit path) close to 20 km depending on route choices and transport plans.
Duration
Expect 5–6 hours of hiking, including breaks, photos, and river rest stops — longer if you plan to camp or fully explore scenic spots.
Elevation Range and Terrain
The trail’s elevation ranges between 450 m and 730 m, making it mellower than high‑mountain trails but enough to engage most hikers.
Terrain includes compact soil, forest paths, stone steps, occasional ropes for semi‑steep spots, and paved forest roads on the approach segment.
Trail Difficulty
Rated moderate, the Tonghou Traversing Trail is accessible to hikers with some experience, and even enthusiastic beginners can enjoy it with proper preparation.
Adventure Features Hikers Love
River Crossings and Rope Sections
As the trail winds along water channels, some shallow river crossings and rope‑assisted sections add just enough challenge to feel like true exploration without technical climbing risk.
Solitude Amidst Wilderness
Unlike popular routes, Tonghou often sees fewer visitors — especially on weekdays — granting hikers a sense of isolation and immersion in nature.
Forest Bathing and Scenic Diversity
The lush canopy, hiking sounds, and interplay of light and shadow make the trail a beloved forest Bathing route — a sensory experience as calming as it is scenic.
Camping & Multi‑Day Options
While many hike Tonghou as a single day trek, more adventurous visitors opt for overnight camping near riverside clearings or in designated open spaces along the route.
Campsite Spots
Some unmarked riverside spots make excellent campsites — ideal for starry nights and sunrise views — but always follow Leave No Trace principles and check local guidelines.
2‑Day Trek Ideas
Splitting the hike into a two‑day adventure lets you explore hidden coves, deeper jungle sections, or side peaks like Mt. Dajiaoxi if you wish to apply for additional permits for extended mountaineering.
