Visitors frequently come to the summit of the volcano to watch the sunrise and/or sunset. One attraction of the park is Hosmer's Grove, a unique forest of trees including deodar (Cedrus deodara) from the Himalayas, sugi (Cryptomeria japonica) from Japan, eucalyptus from Australia, and several species from North America (pine, spruce, cypress, fir, and others). Native plants and trees are also present in the forest but are not common due to the little light available (because of the taller alien trees).
