Boca Catalina
Small, calm sandy bay on the Malmok coast with clear water and easy shore snorkelling, five minutes north of Palm Beach. Little shade.
Boca Catalina is a small, sheltered sandy bay on the Malmok coast in north-west Aruba, about a five-minute drive north of the Palm Beach high-rises on the road to the California Lighthouse. The Aruba Tourism Authority describes clear, calm water with easy entry from the sand, which makes it one of the island's most popular spots for snorkelling straight from the beach. Steps lead down from a roadside parking area.
Is Boca Catalina good for snorkelling?
Yes, it is one of the classic shore-snorkelling spots on the west coast. The bay is small and the water clear, and the limestone and rocks along its edges attract reef fish within a short swim of the sand. Because it is shallow, it suits beginners and families, but do not stand on coral or rocks, and keep fins off the bottom. Snorkel boats also visit this stretch of coast, so stay close to shore and use a brightly coloured snorkel or float if you swim further out.
Is it safe for swimming?
On most days, yes: the bay faces west, in the lee of the trade wind, and the tourism authority calls the water calm. The usual west-coast caveats apply. The edges are rocky, and conditions change on the rare days when wind or swell comes from the west. If the water looks choppy, choose sandier Arashi Beach or wait for a calmer day.
Is there shade at Boca Catalina?
Only a little. The tourism authority mentions some makeshift beach huts, and lists no rentals or bars on the sand. Bring an umbrella, water and snacks, and take your rubbish home. The beach is narrow, so a handful of families can fill it at weekends.
When is it quietest?
On weekdays, the tourism authority notes, you may have the bay almost to yourself; at weekends it draws a mix of local families and visitors. Mornings usually bring the flattest water and the best visibility before the afternoon breeze picks up the surface. The bay also faces the sunset.
What is nearby?
Boca Catalina sits between Malmok Beach, with its rocky coves and the offshore wreck of the Antilla, and Arashi Beach further north. Many visitors snorkel all three in one morning and finish at the California Lighthouse. For equipment and reef etiquette, see snorkelling in Aruba.
What to do here
Getting there
From Palm Beach, drive north on the coast road through Malmok towards the California Lighthouse; Boca Catalina is on the left after about five minutes, with parking beside the road. Arubus L10A (Oranjestad–Arashi) runs along this road; ask the driver for the nearest stop and check times on arubus.com.
Local tips
- Bring everything. Facilities are minimal: pack shade, water and snorkel gear.
- Be visible. Boats pass along this coast; use a bright float if you swim beyond the bay.
- Go in the morning. Flatter water and better visibility before the afternoon breeze.
