Located off of highway 30 near mile marker 38, you'll find a gravel parking lot. Following the trails to the east for about 500 yards will bring you to the light beacon. Walk about 600 yards from the lighthouse along the gnarled, Mars-like coastal landscape and you will find the Nakalele Blowhole. A the blowhole, water can spew up to 100 feet when the waves are right. The trail is not very well laid out, and mainly made of volcanic rock that has suffered years of erosion from the extreme winds, and salt water (hence, the name).
You'll find the Acid War Zone Trail
on the north side of the West Maui Mountains, Haleakala Crater
's sister mountain on Maui.
The Acid War Zone Trail
was named by hikers who described the view as looking like the site of an acid war.
