How to get to Boca Catalina snorkeling spot?

Boca Catalina is located on the northwestern tip of Aruba, on the way to the California Lighthouse. From Oranjestad and the Palm Beach resorts, drive to the north side of the island. Driving time is approx. 20 minutes from the capital, and 5 to 10 minutes from Palm Beach.

Both beaches (Boca Catalina and Catalina Cove, a second entry point) are marked with signs on the left side of the road, and have a parking area.

Boca Catalina is also serviced by bus from Oranjestad. See Arubus website for details. If you prefer to go there by boat, most boat tours departing daily from Eagle Beach and Palm Beach include a snorkeling stop on Boca Catalina’s reef.

Water entrance for snorkeling Boca Catalina

This portion of Aruba’s shoreline is mostly rocky, but Boca Catalina Beach provides safe access to the water, via a sandy beach in the rocks. Enter the water here, and swim away from the shore.

Boca Catalina snorkeling tips

When snorkeling Boca Catalina, we advise you to focus on these three areas:

  • The seagrass beds located in front of Boca Catalina Beach, approximately 100m from the shore (↕12-20ft/4-6m). Green sea turtles like to feed and rest on the grassy seabed, making Boca Catalina one of the best sites to spot sea turtles in Aruba. Go in the morning if you want to have the best chance to see them, as they tend to swim away when many snorkelers are in the water. Peacock flounders and flying gurnards also occur in the seagrass.

Green sea turtles are frequently seen in Boca Catalina’s deep seagrass meadows.
  • The area bordering the rocky point marking the north end of the beach (↕3-7ft/1-2m). Here, the seabed is mostly rocky, and quite a few coral and sponges have colonized it. You might see dozens of fish species in this shallow area, particularly boxfish, needlefish, wrasse, butterflyfish, and shoals of hundreds of juvenile grunts. Underwater visibility may vary.

Most of the snorkeling in Boca Catalina is beyond the buoy line, out of the swimming area. Beware of the many tour boats entering the area. Sea conditions are usually perfect on this spot but don’t leave the swimming area if you don’t feel comfortable with snorkeling, or if usual light currents get stronger.

When in Boca Catalina, you may also want to snorkel Malmok Beach, Tres Trapi and Arashi Beach, which are all located a few hundred yards away.
