Fodor's Expert Review Lava Tree State Monument
Puna
Free
Tree molds that rise like blackened smokestacks formed here in 1790, when a lava flow swept through the ohia forest. Some reach as high as 12 feet. A meandering trail provides close-up looks at some of Hawaii's tropical plants and trees, and there are restrooms and a couple of picnic pavilions and tables. Mosquitoes live here in abundance, so be prepared.
