今須宿問屋場
Toiyaba were places in post towns where Daimyo and officials went to get or exchange horses, personnel, and perform various administrative tasks. They existed in every post town, however very few Toiyaba exist today. The Imasu-juku's Toiyaba is Gifu's sole remainder.
関ケ原鍾乳洞
A 518-meter-long cave that maintains a temperature of 15 °C (59 °F) all year round. The cave has many stalagtites and stalagmites, some of which have been noted and named for their unique appearances, such as "The Giant's Foot" (巨人の足) which really does look like a giant leg and foot. It also contains fossils and there are trout in the river that runs through it. The pathway is flat and has no stairs, so it's known for being a good cave for families with younger children.
エコミュージアム関ケ原
A small museum featuring exhibits about the flora and fauna found in western Gifu Prefecture. The exhibits are interactive and fun for children.
大谷吉継の墓 Ōtaniyoshitsugu no haka
One of the westernmost memorial markers in the town, this spot marks both the encampment and final burial site of Ōtani Yoshitsugu, one of the Western Alliance's main commanders. When he realized the defections of Kobayakawa Hideaki and others and the increasingly small likelihood of Western victory, he committed seppuku, or ritual suicide. Best reached by bicycle (although it is within walking distance, it just takes longer to get to than most other sites), but the final stretch up the mountain must be walked.
奥平貞治の墓
A leader who fought under the traitor Kobayakawa. He died while attacking Otani Yoshitsugu's army. The grave was built here by one of his descendants.
