A 33-year-old visitor from Australia fell 50 feet while hiking in Maui’s Waihou Springs Forest Reserve in Olinda on Wednesday and was hospitalized in serious condition.

Makawao firefighters found the male visitor from Perth, Australia at the bottom of a ravine, 20 minutes from the trail head.

The hiker lost his footing while walking along a steep ledge near the area known as the “Caves,” and fell about 50 feet onto the rocks below, according to fire department officials. He was hiking with three other friends on the Waihou Springs Trail.

The fire department’s primary helicopter was occupied at a brush fire in West Maui at the time, so Air 2, a backup aircraft, was dispatched shortly after it left the West Maui firefighting effort. At 4:30 p.m., Air 2 airlifted the man to paramedics at a landing zone on Olinda Road. He was taken to Maui Memorial Medical Center in serious but stable condition.
