Myoujin-dake
This is an easy hike near the famous "onsen" town of Hakone. From the bus stop, walk up the trail to the ridge, just below Kintoko-san (mountain). Turn right, and follow the ridge south-east to first Myujin-dake (a good place for lunch), and then Myouho-dake. From there descend into the village of Miyagino, and take the bus back to Hakone-yumoto. There are great views of Mount Fuji, the Pacific Ocean, and the Hakone valley.
