Maui has some of the best snorkeling in Hawaii. Here's what you need to know about water quality at the top spots — and how to pick a tour that goes when conditions are right.
The crown jewel of Maui snorkeling. This partially submerged volcanic crater sits 3 miles off the coast near Mā‘alaea and has some of the clearest water in Hawaii — regularly 80–150 feet of visibility. Being offshore and in a protected conservation district, water quality is consistently good. Only accessible by boat tour (30–45 min from Mā‘alaea or Kihei). Book early in the morning for the best conditions before afternoon trade winds arrive.
"Turtle Town" is a stretch of reefs between Wailea and Makena known for reliable green sea turtle encounters. Most Molokini tour boats stop here on the way back. Open ocean location means generally good water quality. The area benefits from the clear, south-facing exposure of Wailea's coastline.
One of Maui's best-kept snorkeling secrets when summer swell is calm. A protected marine life conservation district on the northwest tip of Maui. Excellent coral and fish diversity. In winter it becomes a world-class surf break, making it inaccessible for snorkeling. Check conditions carefully — runoff from the valley can affect clarity after rain. See our Honolua Bay water quality page for current status.
A calm, protected crescent bay on Maui's northwest coast with historically low bacteria counts and generally good clarity. Great for independent shore snorkeling. Shallow entry, protected from swell most of the year. Check our Napili Bay water quality page for current conditions and what to watch for after rain.
One of Maui's most reliable year-round snorkel spots. Protected headlands on both sides create very calm conditions most days. The bay has consistently good water quality ratings. Excellent for families — calm entry, turtles frequent the area, and the reef is in reasonable health.
Two connected beaches in the Wailea area with good snorkeling along the rocky point that separates them. Easy shore access, free public parking. Ulua Beach water quality has historically been good. Ideal for independent snorkelers staying in Wailea.
The Hawaii Department of Health recommends staying out of the water for at least 72 hours after heavy rain. Shore snorkel spots near stream mouths, valleys, or developed areas are most affected. Offshore tours to Molokini are far less affected by rain. After a storm, book a boat tour rather than shore snorkeling for the best water quality.
