The winter storm that hit the Hawaiian parks last week forced closures and caused damage in the parkâs summit area. Power and phones were finally restored around noon on Tuesday after six days without either service. The Summit Visitor Center and restrooms had been closed due to both the power failure and water damage. Wind gusts of 80 mph tore roofing off of the summit observation building, and large amounts of rain flooded the Sliding Sands Trail and left the pathway destroyed. The trail will remain closed due to safety concerns. Crews are assessing wilderness cabins for damage. Permits are being issued into the wilderness for Holua Cabin only. Backpackers can enter the wilderness via the Supply Trail by Hosmer Grove. Hosmer Grove Campground and Nature Trail are open. Campers are advised to check in at the visitor center for weather updates. All visitor facilities were open as of Wednesday. Additional information can be obtained by calling the main park line at 808-572-4400.
