An easy, enjoyable walk through quiet rainforests takes you to the entrance of the Thurston Lava Tube
, which continues to awe every visitor with its tranquil, almost eerie presence at Hawaii Volcanoes National Park
. Down an easy trail lined with lush ferns and tropical trees, the lava tube—now hundreds of years old—invites visitors with comfortable lighting that preserves the mood of this volcanic land formation. (Photo: apasciuto/Flickr)
