Although the main visitor use area is outside of the path of totality we are still expecting large crowds for the Aug. 21 eclipse event. Our group campground is reserved for that time period and our regular public campground (Lava Flow Campground) is likely to be filled up during that time period as well. Please note that campsites in the Lava Flow Campground are available on a first come-first served basis and there is a 14 day limit for occupying a campsite. Please avoid parking or driving over dry grass in the BLM Monument or along the margins of the highway during this period of high fire danger. No fires are permitted in the Monument and Preserve except for charcoal fires in campsite grills and camp stoves.

Regularly scheduled interpretive programs will be cancelled during the period from August 16-24 so we may provide special events and programming about our night skies and the total solar eclipse on August 21. More....
