5 Best Sights in Colombia

Relatively easily to get to, Bahia Concha is a 30-minute taxi ride from town and is an attractive bay set in the region's typical bosque seco (dry indigenous forest) with warm, gently lapping water. It is, however, a popular destination on weekends and local holidays, so best to avoid at those times. Much of the first part of the beach is cluttered with metal frames for shade canopies, and there are several options for buying cold drinks and a freshly grilled fish lunch. Plan to come early, and head down to the far right end of the beach—you can even ask for a cooler when you buy drinks and take it with you. Here you will find empty sands, a patch of shade and, a little way up the rocky side of the bay, some degraded but still beautiful patches of coral for snorkeling. Although the beach is within the borders of the PNN Tayrona, you do not have to pay the full entrance fee, only a small fee to local administration. Best for: partiers; walking; snorkeling. Amenities: toilets; food and drink.

As if lifted from a soft-drink commercial, Johnny Cay is a small, palm-fringed island surrounded by transparent aquamarine waters some 20 minutes by boat from San Andrés. (Any tour operator can fix you up with transport.) It's essential to escape to this deserted Caribbean island on an out-of-season weekday—on weekends the hordes descend upon the island's white sandy beaches and lather themselves in coconut oil. Meals and drinks are available at any one of the shacks set up along the beach, or they can be arranged by your operator. Be sure to bring extra cash to rent shade and loungers. Basic transport with a tour operator will cost around 25,000 pesos, and you can often combine this trip with visits to nearby Acuario and Haynes Key.
