After a scenic boat trip down the Rio San Juan you arrive at one of the military ranger stations which have been set up to protect the reserve from poachers.
You then have a kayaking trip down the Rio Bartola, a pristine tributary of the Rio San Juan and one of the best places to see some of the reserve's wildlife as you slip silently along the river under the towering rainforest canopy.
After the kayaking a guide will give you a choice of trails which run through the forest. These vary from a gentle two-hour stroll to more strenuous and challenging treks, depending on your preference.
You can expect to see howler monkeys, brightly coloured poison dart frogs, a wide range of birdlife including trogons, manikins, tanagers and if you're lucky scarlet macaws. There is also an endless variety of flora and the chance to see larger mammals such as ocelots.
