Maui's famous Secret Beach — water quality, directions, conditions, and what to expect
📍 South Maui, near Makena State Park
Makena Cove sits on the remote South Maui coast in one of Maui's driest areas. The surrounding landscape has minimal urban development and limited stream inputs. The open ocean exposure and rocky cove structure promote good water circulation and natural flushing. These geographic factors suggest low baseline bacteria risk under normal conditions.
As with all beaches, conditions can change after rainfall. Avoid entering the water for 72 hours after heavy rain in the Makena area, and always assess the visual appearance of the water — if it appears brown or murky, do not enter.
Based on: remote location, low development density, open ocean exposure, South Maui dry climate
From Wailea, take Wailea Alanui Drive south. The road becomes Makena Alanui Road after the Andaz Maui. Continue past Big Beach (Makena State Park) — you'll see the large parking lots on your right. About 0.4 miles past the Big Beach entrance, watch for a small lava rock wall and a narrow path on the ocean side of the road. There is a small roadside pullout that fits 5–8 cars. Walk through the opening in the lava rock wall and you'll step onto the cove.
GPS: approximately 20.6072° N, 156.4403° W. Look for it labeled as "Makena Cove" or "Secret Beach Maui" in Google Maps.
The pullout is very small. Arrive before 9am to find parking. The cove gets crowded by mid-morning, especially on weekends. Do not block the road. Overflow parking is available at Big Beach State Park (fee applies).
Makena Cove is sheltered by lava rock walls that block wave energy from the sides, but the cove is open to the south. Summer months (May–September) bring the calmest conditions, though South Maui is susceptible to south swells during this period. Winter brings north and northwest swells that can wrap around the coast and make the cove rough.
Even in dry South Maui, the Department of Health recommends waiting at least 72 hours after heavy rain before swimming. After rain, check the water visually — brown or murky water means conditions may be unsafe.
