From the roadside parking area, the hike is only a quarter mile one way, but plan to spend some time here because the scene is spectacular. The short trail descends a gully to a viewpoint where most people stop to look then turn back. Continue down the faint trail into the "acid warzone," an area of deeply pocked and utterly mangled lava rocks, under constant assault by the wind and sea. A terraced area offers good viewing of the blowhole from a safe distance.
The Nakalele Blowhole formed as a result of the undercutting of the rugged lava shoreline by the continuous pounding of north Maui's powerful surf. The manhole-sized opening creates geyser-like eruptions reaching up to 100 feet high during heavy surf periods. Use extreme caution if you go near the blowhole.
For a longer loop hike, continue west overland (there are faint traces of trail in some spots, but you're pretty much on your own) to a light beacon and a large mushroom-shaped rock, before finding a faint trail that returns to the road a half mile from where you parked. Evaluate wind and surf conditions before attempting either. The hill above the trailhead offers stunning views of the north coast as far as Kahakuloa Head.

Nakalele Blowhole: The blowhole is caused by the ocean's undercutting of the rocky shoreline. During periods of high surf, the blowhole can spout up to 100 feet high. Keep a safe distance.
