From the visitor center, two trails lead into the forest:xa0 the shorter Los Helechos trail is about 1.2 miles (2 kilometers), and the more challenging Los Musgos trail is about double the length and mostly uphill. Both trails pass gorgeous waterfalls where you take a refreshing swim. As you hike, keep your eyes open for rare orchids and quetzals—the magnificent birds have bright red chests, green fuzzy feathers on their heads, and long tail feathers. The reserve is best explored in conjunction with a multi-day excursion. Most tours leave from Antigua or Guatemala City and include visits to the alpine town of Cobán, Lanquin Caves, Rey Marcos Caves, and the limestone pools of Semuc Champey National Park.
