Start at West Maui’s signature beach. The long stretch of sand has consistent swimming conditions with a gentle sandy bottom. Head to the north end at Black Rock for the island’s most accessible snorkeling — sea turtles, parrotfish, and triggerfish cruise the lava wall in 5–15 feet of clear water. Arrive early for calmer conditions; afternoon trade winds stir up surface chop.
South Maui is sunnier and drier than the west side. Wailea Beach is sheltered and calm, excellent for morning swimming. Use the Wailea Beach Path to walk to Polo Beach (quieter, less crowded) or Ulua Beach (reef snorkeling at the rocky point). The south shore is typically calmer when north swells hit the west and north coasts during winter months.
Water quality note: Check Kaʻanapali and Wailea pages before entering. South Maui beaches generally have excellent water quality due to dry conditions.
| Kaʻanapali to Wailea | 45 min via HI-30 through Maʻalaea |
| Best schedule | Day 1: Kaʻanapali 7–11 AM, Lahaina town for lunch. Day 2: Wailea 8 AM, beach-hop via path, lunch at The Shops at Wailea |
| Parking tips | Kaʻanapali: free at north end by Black Rock. Wailea: free public access lots off Wailea Alanui Dr (arrive by 9 AM) |
| Gear rentals | Snorkel sets available at shops in both Kaʻanapali and Wailea ($10–$20/day) |
Snorkel gear: Both Kaʻanapali and the Wailea Beach Path beaches offer excellent snorkeling. Own gear saves rental costs and fits better. Rent in Lahaina or Kihei if needed.
Comfortable walking shoes: The Wailea Beach Path is paved but covers about a mile between beaches. You will want proper footwear for the walkway and reef shoes for the water.
Reef-safe sunscreen: Required by law. South Maui is the sunniest part of the island. The UV index frequently exceeds 11 (extreme) during midday hours.
Winter: Kaʻanapali can get moderate surf from wrapping north swells. South Maui (Wailea) stays calmer. Whale watching is outstanding from both coasts December through April.
Summer: Both areas are calm and warm (80°F water). Snorkeling visibility is at its best. Trade winds create afternoon chop — aim for morning water activities.
After heavy rain, wait at least 72 hours before entering the ocean. Check each beach’s water quality page for live advisory status.
