The Monkey Trail emerges at Playa Potrero, about 16 kilometers southwest of Sardinal and immediately northeast of Playa Flamingo, from which it is separated by Bahía Potrero. The gray-sand beach curls southward for about three kilometers from the rustic and charming fishing hamlet of Potrero and is popular with campers during holidays.

North of Potrero, a dirt road leads to Playa Penca, a beautiful beach backed by a protected mangrove estuary—that of the Río Salinas—and rare saltwater forest replete with birdlife, including parrots, roseate spoonbills, and egrets.

From Penca, the road snakes north three kilometers to Playa Azúcar (Sugar Beach), a narrow 400-meter-wide spit of sun-drenched coral-colored sand that just might have you dreaming of retiring here. There’s good snorkeling offshore. Beyond Playa Azúcar, the rugged dirt road leads to Playa Danta.
