One of a trio of Dewa peaks, 1,504-meter (5,000-foot) Yudono-san, is generally the last on pilgrims' rounds. You can descend on foot in a few hours from Gas-san, but it involves interpreting signs in Japanese, a bit of exertion, and slippery metal ladders, and you'll want to check with the tourist information folks about current conditions. Buses make the 80-minute (¥1,490) run between Tsuruoka and Sen-in-Zawa, a trailhead for a short climb to the summit, where you must
make a small monetary donation and be purified in a secret ritual that you are forbidden to photograph or tell anyone about. Once cleansed, don't miss the last bus back down to Tsuruoka, which leaves promptly at 4:30 pm.
