Cave in the lava beds.

Lava Beds National Monument

My boys (ages 10 and 19) loved these caves, and didn't want to leave! They especially enjoyed Valentine Cave with its labyrinth of passages. 777 caves have been discovered in this park, making it the most dense cave system in all of America.

Note: wear long pants, and bring plenty of food and water as there aren't any restaurants around. Flashlights can be checked out free at the visitor's center, but must be turned in by 5:30. Also, several caves close at 5:30, so plan on coming early. These caves are to be toured on your own -- there are not tour guides.
