Haleakalā in April: what the park service says
April is the first month after the summit's named rainy season ends, though the cabin guidance still says to plan for rain in every season. It is also when autumn crater stays come within reach: Hōlua, Kapalaoa and Palikū, the three historic cabins, can be booked on Recreation.gov as much as half a year before the stay, so an April booking session reaches October. Each costs $75 a night and has twelve padded bunks, a wood stove and a propane stove, and no electricity. Every overnight in the park, cabin or tent, counts toward a cap of three nights in any 30 days. Getting there means hiking: 3.7 miles to Hōlua is the shortest walk.
