Isla Catalina is a small uninhabited island about 2.5 kilometres off the Dominican Republic’s south-east coast, opposite La Romana. It is a tender call with no pier and no permanent facilities — ships anchor offshore and run tenders to the beach, and whatever you use during the day is brought in for it. The draw is the water: The Wall, a vertical reef drop-off, is one of the best dive and snorkel sites in the country.
If you are looking for Avalon, the Casino building and the buffalo herds, that is Catalina Island, California — a completely different island on the other side of the continent. This guide is about Isla Catalina in the Dominican Republic.
Isla Catalina is the closest thing the Dominican Republic has to a desert-island call. There is no town, no port, no road and nobody lives there. It sits inside the national park system, overnight stays are not permitted, and the island’s highest point is about eighteen metres.
That makes for an unusually simple port day. You are going to a beach with excellent snorkelling off it, and the decisions are which water activity to do and whether to bother with anything else at all.

Getting ashore
Ships anchor off the island and run tenders in. There is no pier, so the landing is at the beach itself rather than onto a dock — worth knowing before you decide what to carry ashore and what footwear to wear.
As with any tender call, rough seas can cancel the whole thing. There is no alternative berth here, so a cancelled Isla Catalina day is usually replaced with a sea day rather than a different port.
Because the island has no infrastructure, take what you need with you: water, sun protection, and cash in small notes if your ship’s arrangement includes independent vendors. Reef-safe sunscreen is the right choice in a marine reserve regardless of whether anyone checks.
The beach and what is actually there
White sand, clear shallow water, and reef close enough to the shore that you can snorkel straight off the beach — which is unusual and is the reason this island is worth a call at all.
What is not there is a resort. There are no permanent shops, bars or restaurants, and no commercial buildings, because the island’s protected status does not allow them. On a cruise day the beach is set up temporarily: excursions typically include loungers and umbrellas, a Dominican barbecue buffet of grilled meats, rice, salad and tropical fruit, rum punch and soft drinks, plus snorkel gear, kayaks and paddleboards.
The practical consequence is that what you get depends entirely on what your ship or excursion provides. Costa runs its own private beach area on the island; other lines package it differently. Check what your booking includes rather than assuming there will be somewhere to buy lunch.
The Wall, The Aquarium and Captain Kidd’s wreck
The diving and snorkelling is the reason serious divers rate this island above its better-known neighbour.
The Wall is a vertical reef drop-off on the island’s flank. The top sits at roughly 12 to 18 metres (40 to 60 feet) and the face descends past 30 metres, dropping away into deep blue with hard and soft corals down its length. Some sources put the top of the wall shallower, at around 5 metres. It is a dive site first — snorkellers can see the rim and the top of the drop in good conditions, but the wall proper is for divers with some experience.
The Aquarium is the gentler counterpart at around 9 to 14 metres (30 to 45 feet), sandy-bottomed and busy with tropical fish, parrotfish, moray eels, stingrays and sometimes turtles. This is the site for newer divers and confident snorkellers.
Captain Kidd’s shipwreck is the surprise: a seventeenth-century wreck lying in roughly three metres (10 feet) of water, shallow enough to see from the surface and to snorkel comfortably. It is now colonised by coral and fish.
Visibility around the island is generally good, commonly in the 10 to 20 metre range and considerably better on a calm day.
Getting there from La Romana and Bayahibe
If your ship calls at Isla Catalina directly, you tender and this section does not apply.
If you are calling at La Romana instead, Isla Catalina is a standard excursion — roughly half an hour by catamaran or speedboat, and a comfortable half or full day. Boat transfers have been quoted around US$20, though prices vary by operator and what is included.
Bayahibe, about 25 minutes’ drive from La Romana port, is the other departure point and the base for most of the independent dive operators working these reefs. If diving The Wall properly is your goal rather than a beach day, a Bayahibe dive operator is the route to it.
Accessibility
This is a difficult call for anyone with mobility limitations, and it is worth being blunt about why.
The tender is the first obstacle, and there is no pier at the other end — you step off onto sand. There is no wheelchair-accessible infrastructure on the island because there is no infrastructure at all, and beach wheelchairs are not something you can rely on being available. The beach itself is flat and short once you are on it.
If tendering is difficult for anyone in your party, this is a call to consider skipping, or to enjoy from the ship.
Isla Catalina compared with Saona
Both are Dominican island beach days and cruise passengers routinely have to choose. They are not the same experience.
- Isla Catalina is smaller, closer and quieter, with better reef right off the beach. Reached by tender from the ship or a half-hour boat from La Romana. Best if snorkelling or diving is the point
- Saona is bigger, further, and the classic palm-fringed postcard, usually sold as a full day from Bayahibe with a stop at a natural pool sandbar. Better if the picture-perfect beach day is the point, but it eats the entire port day
If your itinerary calls at Isla Catalina directly, take it as it comes and enjoy the water. If you are choosing from La Romana, pick Catalina for reef and a shorter day, Saona for the scenery and a longer one.
Weather and when you will be calling
Hot and humid year round, generally high twenties to low thirties Celsius. December to April is the dry peak season and the bulk of cruise calls, with the calmest seas — which matters more than usual at a tender port. May and November are quieter and wetter. The Atlantic hurricane season officially runs June to November, peaking August to October.
Sea state is the thing to watch here. Calm water means a smooth tender, better visibility and a better day underwater.
Common questions
Is Isla Catalina a tender port?
Yes. Ships anchor offshore and tender to the beach. There is no pier.
Is it the same as Catalina Island in California?
No, and they are frequently confused. Isla Catalina is in the Dominican Republic, near La Romana. Catalina Island, California is off Los Angeles.
Does anyone live on the island?
No. It is uninhabited and protected, and overnight stays are not permitted.
Are there shops or restaurants?
No permanent ones. Food, drink and equipment come from your ship or your excursion.
Can I snorkel The Wall?
You can see the rim and the top of the drop in good conditions, but The Wall is primarily a dive site. The Aquarium and Captain Kidd’s wreck are the better snorkelling.
How do I get there from La Romana?
By catamaran or boat, about half an hour. Book as an excursion rather than turning up.
Catalina or Saona?
Catalina for reef and a shorter day; Saona for the classic beach and a full one.
