Mt. Batongguan

Pre-trip Notes

Gear

A lightweight summit pack comes in handy for the D2 summit round trip; the full pack stays at Guangao Lodge.

D2 starts at 04:15 in the dark; plan for a headlamp

If you only stay at Guangao Lodge, leave the slippers and sleeping mat at home: the lodge provides slippers and the bunks have thick mattresses

Hornets

Lele Lodge has a toilet, and there is a hornet warning sign nearby. Autumn is when colonies are largest and most territorial. Wear light colours, skip perfume, and don't walk with earphones so you can hear the warning buzz

If a single scout hornet comes, stay calm and wait for it to leave; if it doesn't, walk briskly away in the direction opposite to where it came from. Don't wave your arms or clothes, and don't spray insecticide

If a swarm attacks, don't lie down; get away fast, but watch your feet so you don't fall off the slope in a panic. After a sting, leave the spot first; for chest tightness, shortness of breath, a tight throat or dizziness, call 119 at once

Guangao Lodge

There are three kinds of slippers: outdoor, indoor and kitchen. Boiling water and the sink are inside the kitchen only

The bunks have fairly thick mattresses and partitions between places

The sink is fed straight from a stream higher up; there was plenty of water when the author arrived in mid-October

The common room outside the kitchen has several charging sockets with Type-A/Type-C ports

Each map shows that day's route, traced along the actual trail and terrain: the line runs from light to dark as it climbs, with a green dot at the start and a red dot at the finish. The rise and fall below it is that day's elevation, in metres, on the left.

Under forest cover or in a canyon, GPS sometimes drops for a few minutes — those stretches on the map show as straight lines. Recording was on; the GPS simply had no fix. Those are not stretches that went unwalked. Stretches that genuinely weren't recorded are called out separately, in the notice above.
