La Perouse Bay

La Perouse Bay, also called Keone'o'io, is a rugged South Maui lava-rock bay beyond Makena, with tide pools, rough terrain, coastal trails and no lifeguards.

La Perouse Bay, Maui

La Perouse Bay, located on Maui's south shore in the Ahihi Kinau Natural Area Reserve, has a rocky shoreline. The bay features several small coves between rocky points, and these areas are often covered with tide pools. Some coves have small sandy sections, but most have coral-rubble shoreline. The road that leads to La Perouse Bay is narrow, and the last stretch to the bay is unpaved and rough with lava rocks.

The bay is somewhat protected from strong currents, but during storms and heavy surf, the water inside the coves can become very turbulent. La Perouse Bay has a reputation as a snorkeling area, but the bay itself usually has poor visibility. The small coves along the northern side of the bay are part of a protected nature reserve, and access rules can change. Follow all posted signs and stay out of closed or restricted areas.

One nearby ocean area is Moanakala, locally known as Dumps, named after a rubbish dump that used to be located here. It is in the northern portion of the reserve, just south of Ahihi Cove. The water entry can still be rough, and the snorkeling at Dumps is not suitable for beginners because wind, chop and occasional strong currents can make conditions difficult.

When visiting this area, wear sturdy shoes because sharp lava rocks cover much of the shoreline. The stark lava fields, bright blue ocean, coral-rubble beaches and waves hitting the cliffs make this a memorable photo stop. Keep in mind that the bay is part of a protected natural area, so do not harass or approach marine life, and do not remove or damage rocks, plants or coral.

La Perouse Bay is named after French naval officer and explorer Jean-Francois de La Perouse, who reached Maui in 1786. The Hawaiian name of La Perouse Bay is Keone'o'io.

Frequently Asked Questions

Why is La Perouse Bay also called Keone'o'io?

Keone'o'io is the Hawaiian place name for the bay. La Perouse Bay is the later name tied to the French explorer Jean-Francois de Galaup, comte de La Perouse.

What makes the lava landscape here unusual?

The black lava fields come from one of Haleakala's youngest lava flows. USGS research places the flow sometime between A.D. 1480 and 1600, older than the old 1790 date often repeated in guidebooks.

What is the Hoapili Trail?

The Hoapili Trail, also called part of the old King's Highway, begins near La Perouse Bay and crosses rough lava shoreline. It is exposed, hot and best started early with plenty of water.

Why do people look for dolphins at La Perouse Bay?

Spinner dolphins are sometimes seen offshore in this part of South Maui. Watch quietly from shore or from a legal distance on the water, and never chase or crowd them.

How does La Perouse Bay compare with Ahihi Cove?

Ahihi Cove is the more direct calm-condition snorkeling stop, while La Perouse Bay is better known for lava scenery, tide pools, coastal walking and the end-of-the-road South Maui setting.
