At the top of Mauna Kea

"Above the Clouds" - At the top of Mauna Kea (4205m) in Hawaii last night. Showing both the moon and the milky way in a single exposure from the time-lapse video. The view from the summit is spectacular in every direction.

Does anyone know the best path/trail/access point to photograph the Kilauea volcano and the lava flows? Any recommendations? Mahalo!
