Dawn at the Cave of Refuge: A lava‑field approach to an ocean‑facing lava tube in Mountain View
Set in Mountain View, Hawaii, this compact outing threads a 2.5‑hour route across a raw lava field toward a jungleed approach and a small entrance into a lava tube known as the Cave of Refuge.

Located along the rugged coastlines of Hawaii, Sunrise Cave offers an adrenaline-pumping combination of lava field trekking and spelunking. This trip, guided by The Adventure Collective, invites adventurers to peel back the layers of volcanic history while soaking in spectacular ocean vistas.
