A bit of scrambling to get out of this one.
The labelled caves on the Lava Beds park map are generally developed. This means that they have ladders, cleared sections through the jumbles of rock, or walkways. They do not have lights. The backcountry caves, however, are not developed and usually require a bit more scrambling or technical skills. Lava tubes in general are fairly easy to navigate, so advanced caving skills are not usually needed. Good lighting, head protection, and a lack of fear of the dark and tight spaces are the most important things to have in a lava tube.
