best not to go when there's snow but in the summer, there's Lake Waiau at the top of the summit. it's the only lake on the Big Island. it's an old glacial lake; very small. but the stories are that hawaiian women used to keep umbilical cords and throw them into the lake when someone went up. the lake is 'mystical' and well worth the adventure if you have the time to do it right. go early mornings before the clouds move in.
