Chapter Two: Full Route Description (Life Record)
Prelude: Movement from Previous Day and Taichung Night
Actually, the mountain climbing rhythm starts from the previous day. On the evening of May 23, I took the EMU3000 train to Taichung. Watching the clean train car and changing city lights outside the window, it was hard to imagine facing muddy trails hours later.

Arriving at Taichung Station at 8 PM, the old station glowed with solidity in the night - that was the last comfortable time before departure.

Crossing that Gate: Hehuanshan Tunnel and Start
At 3 AM, we departed from Taichung, swaying along the way to Hehuanshan. Arriving at the tunnel entrance around 6 AM, the cold air instantly woke us up. We crossed the workstation by the tunnel and officially entered 820 Forest Road. It was a strange transition: one moment on asphalt, the next our feet were on wet fallen leaves.

8.4 Kilometers of Psychological Warfare: 820 Forest Road
The first section of the climb maintained altitude around 2500 meters. This section wasn’t very steep, but the length really wore on your patience. The path was wet, with an earthy smell, and your feet kept getting annoyed by appearing gravel and fallen trees.
From Stroll to Survival Mode: 1.6K of Ultimate Steepness
If you thought the first 8.4 km of forest road was just a warm-up, wait until after the water source - the trail will immediately snap you awake.

The slope is so steep you feel your knees hitting your chest. This section isn’t like the forest road where you can chat - every step you take must be checked for stability. This isn’t walking, this is climbing.
Hands and Feet Challenge: 9.6K Vertical Rock Wall
Around 10:55 AM, we encountered the legendary two-story-high rock wall. While it looks scary, there are many foothold options, and there are ropes and chains nearby. I recommend putting away your trekking poles, freeing your hands, and checking your grip before moving.

Final Sprint and Triangulation Point
After crossing the rock wall, the view starts to open up. Reaching the main ridge junction, only 200 meters left to the summit. Though energy was running low, seeing the sign “Mount Bilu 0.2K”, my body automatically squeezed out one last bit of strength.

12:30 PM, finally standing at the 3371-meter triangulation point. The summit had strong wind and fast-moving clouds, but seeing this beautiful scenery, honestly, all the pain from the steep ascent was worth it.
Chapter Three: Discussion and Consequences Warning
Physical Prerequisites
This 12-hour mountain route plan is based on the assumption that “you have solo 100-peak experience” and “can carry weight in continuous climbing”. If you’re a beginner, this 1.6 km steep section might take you over three hours - please start earlier.
Serious Consequences: Getting Lost in Dark
To ensure safety, I set 1 PM as the descent deadline. If you stay too long at the summit and delay descent, you might end up hiking the unstable collapse in the dark with exhausted energy. The risk increases dramatically. Don’t joke about safety.
Extended Thinking: Truth and Misconception in Digital Records
This GPX record showed a typical error. After logging the forest road points at 6 PM, a straight line to Taichung appeared. Analysis revealed this was recording continuing after logging the trail, creating jump errors from driving. This reminds us that when relying on digital tools, we must learn to judge data authenticity and not be misled by system-generated errors.
Mount Bilu is truly deserving of its “mid-level” designation. It lulls you into relaxation with 8.4 km of smooth paths, then teaches you what Hundred Peaks really mean with the last 2 km of steepness. If you want to feel this contrast, a solo Mount Bilu climb is absolutely the best choice.
