South of Kihei and Makena in the Ahihi-Kinau Natural Area Reserve, there is good snorkeling at the remote Keawanaku Beach. When snorkeling at Keawanaku Beach, you may encounter a pod of spinner dolphins that frequent the waters here.
This a challenging place to snorkel, even when the usually high winds are calm.
To reach Keawanaku Beach snorkeling from Wailea-Makena, head south from Wailea along the coast on Makena Road to the very end. There are two dirt parking areas. From the parking area, you will need to hike about a mile to the Keawanaku Beach snorkeling. To reach the snorkeling on Maui by air, you will need to fly into Kahului Airport (OGG) which is located in the middle of the north coast of Maui. It is served by direct flights from the mainland US and also by inter-island flights from several other Hawaiian Islands by regional carriers.
Overall, Keawanaku Beach is the 18th most popular snorkel dive spot of all 21 snorkeling dives in Maui.
