Sulpuhr Banks Trail temporarily closed

A popular trail in Hawai’i Volcanoes National Park is closed for about the next month and a half while its aging infrastructure is repaired.

Sulphur Banks Trail is shuttered through Dec. 12 so National Park Service staff can remove and replace the wooden boardwalk to improve visitor safety at Haʻakulamanu.

Durable yellow cedar will be used to replace the aging facilities.

Two trail crew workers from Yellowstone National Park will assist staff from Hawaiʻi Volcanoes National Park during the 8-week project.

The area, also called Sulphur Banks, is known for the bright yellow sulfur crystals that adorn the lava rocks and for other volcanic gases and steam that seep from the ground.

Exposure to volcanic gas, sun and rain has contributed to the degradation of the boardwalk.

The Sulphur Banks boardwalk replacement project is one of several construction projects in Hawaiʻi Volcanoes National Park.
