This is a good hike to do in the winter since Chiba usually gets less snow and the temperatures are milder. It’s also relatively short so it can be combined with another mountain in the area, like Mt Tomi. I’d recommend using a car for this hike since there is no suitable bus to the trailhead. There is also a convenient parking lot near the start of the trail, in front of Koshoji Temple 高照寺.

It takes about an hour to get to the top of Mt Goten 御殿山. Following the ridgeline, the trail goes past Mt Takatori 鷹取山, and ends at Mt Dainichi 大日山 one hour away. Although the trail is mostly through the forest, there are good views of Mt Tomi and Tokyo Bay from each peak. One might even see Mt Fuji on a very clear day. Although the path continues Southwards down to a road, there is no public transport, so the return is back the same way. It should take a little less than 2 hours to get back to the parking area along the up and down trail.
