Yufu

A small lake (pond, really) at the east end of town, full of fish and flanked with art galleries, tea houses and the Shitanyu bath (below). Walk from the station to here, and you'll have seen most of what the town has to offer.

Waterfall deep in the forest

You can hike to the top of this volcano (由布岳 Yufudake), see the crater and have a very nice view of the surroundings. Allow two hours to reach the crater (from 800m to 1500m). Then there is a junction, the left path leads to the west peak (由布岳西峰 1583m), the right one to the east peak (由布岳東峰 1580m). The east peak is an easy, although steep, walk but the west peak requires more climbing, there are chains to help you. There is also a path connecting the two peaks on the north of the crater but be cautious this section is more technical and requires some climbing knowledge, it is highly recommended to use the south trail for beginners. Be prepared for this long exhausting walk, all the common sense of Hiking applies. Allow 4 to 5 hours in total depending on which peaks you climb. There is nothing on the way, be sure to bring your own food and enough water.
