A typical catamaran tour from the San Juan area leaves from Fajardo marina, about an hour’s drive east. You’ll spend most of the day on the water sailing to spots like Icacos or the Cordillera Islands. Expect snorkeling in decent reefs, swimming off the boat, and a lunch usually served onboard—grilled chicken or fish with rice, beans, and a couple of rum punches. The ride itself is smooth on a cat; you’ll get sun, breeze, and views of the coast, but it’s a group trip so 20-40 people is normal. The boat anchors for a couple of hours at one or two islands where you can swim and snorkel before heading back in the late afternoon.
Best time is December through April when the trade winds are steadier and the water is clearest. Summer and fall can be calmer but rainier, with a real risk of last-minute cancellations from tropical waves. Expect to pay around $110–$160 per person for a full-day tour that includes snorkel gear, lunch, and drinks. Shorter sunset sails from San Juan itself run $70–$95 and are far less crowded.
Pick a full-day trip to the outer islands if you want actual snorkeling and beach time; the ones that stay closer to Fajardo are often better than the pure San Juan harbor departures. Skip the biggest party boats if you dislike loud music and drinking crowds—smaller 12–20 person tours feel more relaxed. Bring reef-safe sunscreen, a waterproof bag for your phone, and a light shirt for sun protection.
