The refuge stretches along the southeastern coast beginning southeast of Puerto Viejo de Talamanca to the town of Manzanillo and on to the Panamanian border. Its limits are not clearly defined. Because of weak laws governing the conservation of refuges and the rising value of coastal land in this area, Gandoca-Manzanillo is less pristine than Cahuita National Park and continues to be developed. However, the refuge still has plenty of rain forest, orey (a dark tropical wood) and jolillo swamps, 10 km (6 miles) of beach where four species of turtles lay their eggs, and almost 3 square km (1 square mile) of cativo (a tropical hardwood) forest and coral reef. The Gandoca estuary is a nursery for tarpon and a wallowing spot for crocodiles and caimans.
The easiest way to explore the refuge is to hike along the coast south of Manzanillo. You can hike back out the way you came in or arrange (in Puerto Viejo de Talamanca) to have a boat pick you up at Punta Mono (Monkey Point), a three- to four-hour walk from Manzanillo, where you find secluded beaches hidden by tall cliffs of fossilized coral. The mangroves of Gandoca, with abundant caimans, iguanas, and waterfowl, lie six to eight hours away. Park administrators can tell you more and recommend a local guide; inquire when you enter Manzanillo village and the locals will point you toward them.
