Kaʻanapali stretches 3 miles along Maui’s West Side, with a long sandy beach backed by resort hotels. The water is typically clear and calm in the morning, with a gradual sandy bottom that makes it suitable for families. The area near Black Rock (Puʻu Kekaʻa) at the north end is the best snorkeling spot, with sea turtles and reef fish in 5–15 feet of water. The famous cliff jump at Black Rock draws crowds in the late afternoon — watch for swimmers below before jumping.
Water quality note: Check the Kaʻanapali Beach page for current conditions. The beach historically rates low on bacteria testing, but heavy rain can send runoff from the resort areas into the nearshore water. The area near the Hyatt at the south end receives more runoff than the northern section.
If Kaʻanapali has elevated surf or advisories, Wailea Beach on Maui’s south shore is 45 minutes by car via the Honoapiʻilani Highway. Wailea’s crescent beach sits between two lava rock points that provide wave protection, and the water quality is consistently among the best on the island.
| Parking at Kaʻanapali | Free public parking at Whalers Village ($3/hr at the garage) or at the north end near Black Rock. Resort parking: $25–$45/day |
| Best swimming time | 7–10 AM before trade winds create afternoon chop |

| Sun protection | Reef-safe sunscreen required by Hawaiʻi law. Kaʻanapali has limited natural shade — morning sessions or umbrella recommended |
Snorkel gear: Kaʻanapali’s Black Rock area is one of Maui’s best snorkeling spots. Bring your own gear or rent from shops along the resort walkway ($10–$15/day). Prescription mask inserts are available at some shops.
Reef-safe sunscreen: Required by law in Hawaiʻi. Apply generously — Kaʻanapali has virtually no natural shade along its 3-mile length.
Cash for parking: Some parking areas near Kaʻanapali are metered and may not accept cards. The free parking near Black Rock fills quickly — arrive before 9 AM.
Winter (November–March): Kaʻanapali faces west and is partially protected from north swells, but large swells can wrap around and create moderate surf. Humpback whale season brings incredible viewing from the beach — look for breaching and tail slaps offshore between December and April.
Summer (April–October): Kaʻanapali is at its calmest, with warm 80°F water and excellent visibility for snorkeling. South swells rarely affect this west-facing coast. Trade winds create afternoon chop, so plan water activities for morning.
After heavy rain, wait at least 72 hours before entering the ocean. Check each beach’s water quality page for live advisory status.
