Snorkeling Black Rock at Ka’anapali Beach is very popular. Despite being busy, it is a big beautiful beach, so we have never had trouble finding our own space.
Note: This page is a sample from our popular Maui Snorkeling Guide eBook available here.
The snorkeling is on the north end of the beach around Black Rock, the rocky point. Black Rock itself is considered a Hawaiian historic area and the Hawaiian name is Pu'u Keka'a. We find the snorkeling here to be good, but not great. There is really no reef to speak of, just a little coral on the rock wall, and lots of fish. The snorkeling is along the wall, and out around the point where there can be a very strong current, so stay aware and only go out if it is calm.
Ka’anapali Beach is home to some ritzy dining, hotels, and shopping. The resorts on the north end of the very long Ka’anapali Beach, within a reasonable walk of snorkeling Black Rock, are Sheraton Maui Resort & Spa, Ka’anapali Beach Hotel, Aston at The Whaler on Ka’anapali Beach, and The Westin Maui Resort & Spa. Several big catamarans come to shore on this beach to pick up and drop off charter guests, as well.
If you are not staying at a resort in the area, you can still access this snorkel spot. There is a public parking option, though it is limited, so it is best to come early to guarantee parking.
From the parking garage (described below), walk out and around to the right. There is a 750 foot long sidewalk, marked by a blue shoreline access sign (No. 213), that leads you to the beach. Once you reach the beach you need to walk to the right another 750 feet on the beach to get to the water entrance for snorkeling Black Rock.
This beautiful sandy beach is made for bare feet. Walk to the very north end of the beach and get in the water. Walk out until you can float and put your fins on.
The edge of the rock itself is the route you follow, otherwise, it is a sandy bottom. On the rock there are many dead corals, but some alive corals, too. If you are inexperienced, don't go around the point. If you are more experienced you can, but be aware as mentioned above that strong currents are frequent here, and wavy conditions can compound the potential danger. After you round the first point, there is a small cove that you can explore inside. If you swim around the outside of the farthest point, it turns into a vertical flat wall over a sandy bottom about 30 feet deep. Make sure to periodically take a look into the deep blue water over the sand, you may be in for a treat. We usually see a Spotted Eagle Ray swimming off into the deep blue off the point. There are many fish all around the rock. We also saw seven turtles on our last visit. Many of them were along the vertical wall outside the farthest point, but there were a few close to shore as well.
The water clarity when snorkeling Black Rock is often fantastic, so even when it gets pretty deep you can see some neat stuff.
This is a good spot to see a good number of fish, though they are not
in big variety. We saw turtles and Spotted Eagle Rays at this snorkel
1. In Kihei get on Hwy 31 (Piilani Hwy) or S. Kihei Rd. heading north.
2. When you reach the intersection with Hwy 311 (Mokulele Hwy) and Hwy 310 (N. Kihei Rd.) turn onto Hwy 310 (N. Kihei Rd.).
3. Follow to the next intersection with Hwy 30 (Honoapiilani Hwy) and turn left, heading initially south. This road is what you could follow to the north shore of West Maui.
4. You will pass by Lahaina and turn into Ka’anapali on Ka’anapali Parkway. If you see the 24 mile marker, you just missed your turn.
5. Go to the end and make the loop and turn right into the first parking garage marked for public beach access. The garage is open from 7am to 7pm. There is parking further down the road if necessary, but this is closest to Black Rock. Just south of the garage is the walking path to the beach.
None, unless you are staying on the beach, then you can use those of your resort.
