Isla de la Juventud is one of Cuba's premier dive destinations, and the diving here is wonderful. The waters are crystal clear, and there are walls, corals, caves, and even a few wrecks. The Centro Internacional de Buceo Colony (tel. 46/39-8181) is the main dive operator on the island, with its dive center at the small marina a few kilometers beyond the Hotel El Colony. Most trips head to Punta Francés ★★, a national maritime park, with a beautiful stretch of white-sand beach fronting a calm and protected sea on the southwestern tip of the island. From here, many of the island's best dive sites are easily accessible. There are a couple of long piers out into the calm waters here. One has a buffet restaurant and bar at the end of it. On shore, there's a small park station, with bathroom facilities and some picnic tables. The park station also has several hundred chaise lounges, which are taken out and spread along the beach whenever a cruise ship pulls in for a day tour. When this happens -- once or twice a week -- this quiet, isolated beach becomes a swarming mass of up to 1,500 sun worshipers. When the cruise ships aren't around, you'll have the joint almost to yourself. Dive trips cost CUC$60 for a two-tank dive, including a full-equipment package. However, if you stay here for any length of time, you are best off buying a multiday, multidive package. Day-trippers can take the boat ride out for between CUC$8 and CUC$30; the higher fees include lunch.

Fishing can also be arranged through Avalon (tel. 72/04-7422 in Havana;, which runs packages based out of the Hotel Rancho El Tesoro or on the live-aboard boat, the Perola. Abundant bonefish, tarpon, and permit are among the dozens of fish species encountered here.

The most popular beaches close to Nueva Gerona are the white-sand Playa Paraíso and the dark-sand Playa Bibijagua. These beaches are 5km (3 miles) and 8km (5 miles) east of town, respectively, and both are served by regular bus service from town. Oddly, the dark-sand Playa Bibijagua is the more popular spot, although neither is a prime beach destination by any standard.
