Best Snorkeling in Puerto Rico: 8 Spots Ranked by Water Clarity

Puerto Rico is a domestic flight for most of the people reading this, which means no passport, no currency exchange and reef you can be floating over four hours after leaving Orlando or Newark. What nobody tells you at the gate is that the island's snorkeling is split in two. A handful of spots you can walk into from the sand, and the good stuff, which almost always needs a boat.

This page ranks eight spots by how clear the water actually tends to be, then tells you which ones are worth the boat fare and which tour makes sense for the time you have.

The short version

• Clearest water on the island: Desecheo Island, typically 80 to 100 feet of visibility, boat only from Rincon.
• Best all round day for a first timer: a Fajardo catamaran to Icacos and Palominito, from $89 (estimated).
• Best reef you can walk into: Playa Carlos Rosario in Culebra, and Escambron if you are stuck in San Juan without a car.
• Six of the eight best spots need a boat. Budget from $65 (estimated) per person for the ride.
• Mosquito Bay in Vieques glows at night but swimming there has been banned for years. It is not a snorkel site.

How we ranked these spots

We ranked on water clarity first, because that is the one thing you cannot fix once you are floating. The ranges below are what these sites typically deliver on a calm morning outside of a swell event, not a best day ever number. After clarity we weighed how hard the site is to reach, whether there is anything alive to look at, and what the trip costs a family of four once boats and gear are counted. Sites that only work for certified divers were left out. So were the bioluminescent bays, because swimming is either banned or pointless for snorkeling in all three of them.

The 8 best snorkeling spots in Puerto Rico

1. Desecheo Island, off Rincon

Typical visibility 80 to 100 feet, and on a flat winter day it goes further. Desecheo is an uninhabited island about 13 miles off the west coast, a wildlife refuge with no beach landing allowed. You snorkel from the boat over coral heads and walls that drop away fast. The crossing takes roughly 45 minutes to an hour and the operators that run it are mostly dive shops in Rincon and Aguadilla, so trips go out when conditions allow rather than on a fixed daily schedule. Expect from $120 (estimated) per person. Not the right call if anyone in your group is nervous in deep water with no sand under them.

2. Playa Carlos Rosario and Tamarindo, Culebra

Typical visibility 30 to 60 feet. This is the best combination on the island of clear water and a shore entry you can handle without a boat charter. Carlos Rosario sits over a ridge from Flamenco Beach on a trail of about 15 minutes, and the reef starts a short swim off the sand. Tamarindo, a few minutes further around, is seagrass rather than coral, which is exactly why green sea turtles feed there most mornings. Getting to Culebra is the hard part, not the snorkeling. Details on that below.

3. Blue Beach and Playa Caracas, Vieques

Typical visibility 25 to 50 feet. Both sit inside the old Navy land that is now a national wildlife refuge, and both are walk in. Blue Beach, signed as Bahia de la Chiva, has a small cay a short swim offshore with reef around its edges. Caracas is calmer and better for kids. The refuge gates open around sunrise and close before dark, there are no rentals or lifeguards inside, so bring gear and water with you.

4. Caja de Muertos, off Ponce

Typical visibility 30 to 50 feet. A protected island reserve on the south coast, reached by boat from La Guancha in Ponce for roughly $30 (estimated) round trip. Sailings concentrate on weekends and cancel in bad weather. The south coast sits out of the north swell entirely, which is why this one is often clear in January when the north shore is a washing machine.

5. Icacos, Palominito and the Cordillera cays, Fajardo

Typical visibility 20 to 40 feet. These are the cays every catamaran out of Fajardo runs to, and they are the reason the east coast carries the island's snorkel traffic. Water is shallow, sandy and protected, the reef is patchy but alive, and boats anchor close enough that a weak swimmer can hold a noodle and still see everything. From $89 (estimated) for a full day with gear, lunch and drinks. This is the highest volume snorkel product in Puerto Rico by a wide margin, and the reviews back it up.

6. Steps Beach and Tres Palmas, Rincon

Typical visibility 20 to 40 feet from May to October, much worse in winter. Steps is a shore entry over a slab of concrete left on the sand, and it sits inside the Tres Palmas Marine Reserve, which protects one of the healthier stands of elkhorn coral left in the Caribbean. From December to March the same water that surfers travel here for makes snorkeling pointless. Time this one for summer.

7. Escambron, San Juan

Typical visibility 15 to 30 feet. A protected cove in Puerta de Tierra, ten minutes by car from Old San Juan or Condado, with a wall that blocks most of the swell. There are fish, small coral heads, occasional turtles and a couple of shipwreck remnants. Nobody flies to Puerto Rico for Escambron, but if you have one free morning in the capital and no car, this beats sitting on Isla Verde. Parking runs about $5.

8. Gilligan's Island, Guanica

Typical visibility 10 to 25 feet. Cayo Aurora, known to everyone as Gilligan's Island, is a mangrove cay off the dry southwest coast, reached by a short ferry from the San Jacinto pier for around $10 (estimated) round trip. The water is waist deep in places and the channels between mangroves are calm, which makes it the easiest snorkel on this list for small children. The ferry does not run every day, so call ahead before driving two hours from San Juan.

Which spots need a boat, and which you can walk into

Walk in from the sand: Carlos Rosario and Tamarindo in Culebra, Blue Beach and Caracas in Vieques, Steps Beach in Rincon, Escambron in San Juan.

Boat required: Desecheo, Caja de Muertos, the Fajardo cays, Gilligan's Island, and Culebrita off Culebra.

The catch is that four of those six walk in beaches are on islands you still have to reach. Culebra and Vieques are served by the public ferry from the Ceiba terminal, about 45 minutes at roughly $2.25 each way for adults. Residents get priority and seats are released online in advance, so visitors regularly find sailings full. Flying from San Juan on a small carrier costs from $60 (estimated) each way and takes 25 minutes. If your plan depends on a same day ferry that you did not reserve, you do not have a plan.

Which tour to book, by how much time you have

One free morning, no car, based in San Juan: skip the boat entirely and walk into Escambron, or book a half day trip that includes hotel pickup. Costs stay under $100 (estimated) per person.

One full day and a rental car: drive to Fajardo and take the catamaran to the Cordillera cays. This is the best value on the island, the sea state is reliable, and you are back at your hotel by early evening.

Two days and real interest in reefs: give a full day to Culebra with an overnight, or fly to Vieques. The clarity jump over Fajardo is obvious in photographs.

Strong swimmer, west coast base, summer dates: Desecheo. Nothing else in Puerto Rican water looks like it.

When the water is actually clear

The north and west coasts take an Atlantic swell from roughly November through March. That swell is why surfers fill Rincon in January, and it is also why snorkeling there in January is a waste of a morning. The east and south coasts, meaning Fajardo, Culebra, Vieques, Ponce and Guanica, stay usable all year, with the trade winds picking up in the afternoons from December to February.

Rain matters more than most people expect. A heavy day of rain pushes runoff out of the rivers and drops visibility near the coast for 24 to 48 hours. Hurricane season officially runs from June 1 to November 30, with the highest risk in August, September and October.

Before you book

Check what the price covers. Some Fajardo trips include gear, lunch and drinks, others charge from $15 (estimated) per person for a mask and fins on top of the fare.

Bring reef safe sunscreen. Products with oxybenzone and octinoxate are restricted in Puerto Rico, and a rash guard does the job better anyway.

Read the cancellation terms before paying. Boats cancel for wind, and the difference between a full refund and a credit is worth knowing in hurricane season.
