A YAMAP activity record dated 11 November 2026 logs an out-and-back from Okura (大倉) to Horiyama (堀山), climbing the ridge known as Baka-one (馬鹿尾根).

The page notes a registered hiking plan, GPX data, and checkpoints. Times between the start and finish are concatenated in the source text, so individual splits are not clear enough to list. No average pace figure is given.
The hiker wrote that Baka-one was as hard as expected. They did not reach Hanatate Sanso (花立山荘) and therefore did not see Mount Fuji. They said they would try to reach Tonodake (塔ノ岳) the following Sunday; that later plan is stated as an intention, not as a completed hike.
