Nakalele Blowhole and Heart Rock Hiking Guide
The Nakalele Blowhole is a short trail on the northern coast on Maui. The hike features a natural land formation known as a blowhole. Blowholes are developed along the coastline and are a small cave that has been formed coastal shelf which leads to an opening along the shore. When waves break along the shore they send a current of water underneath the coastal shelf through the cave and the end result is a powerful plume of mist similar in appearance to a geyser.
Blowholes are unique and usually formed over long geological time periods. One way that they’re formed is through the forces of the ocean eventually hollowing out a sea cave and forcing pressure upwards through the coastal plain. Another way that blowholes are formed is through old lava tubes. Over time pressure from incoming waves and currents can breakdown the shoreline and form an opening. With each incoming wave water is forced through the cave and finds its exit through the surface.
On A Personal Note:
The Nakalele blowhole is a fun short trail to get out and stretch your legs. If you’re driving around the northern tip of Maui the trailhead will be clearly marked by the dozen plus vehicles along the side of the road. For those that have never experienced a blowhole before, this will be a unique experience. Keep your eyes out for an additional picturesque opportunity here. Along the east side of the trail there is a small hole like formation in the lava rock. The hole resembles a heart and is known as heart rock.
Caution: Keep a safe distance away from the blowhole. Water flows through the tunnel and when conditions are rough they can become quite dangerous. People have been swept off the shoreline here from large waves and killed. There have been other instances where people have fallen into the blowhole and sucked down inside and died.

Nakalele Blowhole Trail Conditions:
The Nakalele Blowhole trail is generally in good condition. The is a small use trail that leads from the main highway directly towards the coast where the blowhole is. As the trail starts it it leads directly to the shoreline on a clearly marked dirt path. Once you near the shoreline the dirt gives way to a combination of worn down lava rock and mixed sand. I personally don’t think that shoes are a necessity on this trail but if you have unstable balance they will be beneficial. Many people roll their ankles or slip along the small worn down lava rocks.
