Poas Volcano National Park is popular travel destination and one of the most visited parks in Costa Rica. This park is one of the few places in the world where a visitor is able to look into an active volcano without hiking to the top of one. Volcan Poas continues to be active but had its blowout in 1953. Three craters resulted from the blow. One is large and two other are smaller. One of the smaller has a lake. Clouds gather around the mountain by 10 a.m. It's advisable to visit early.

There are a number of travel facilities for visitors at Volcan Poas National Park, including a visitor center where one can find a small museum, coffee shop, souvenir shop and informative videos shown hourly.

The best time to visit is during dry season. The winds change rapidly, so if there is cloud cover, a hike up to another crater may give enough time for the clouds to pass. Returning to Poas after the hike gives visitors a chance to see the volcano under clear skies.

There is a map of the nature trails available at the visitors' center. From the visitor center, there is a paved road that leads to the crater lookout. From the lookout point above the crater, there is an overview of the Poas volcano. The main crater is 1.5-km (1 mi) wide and 300m (1,000 ft) deep and is one of the largest in the world. It is believed to be active in 40-year cycles and rarely erupts. Currently, it is producing acid-like rain and sulfurous gases. Travelers are advised to stay up to 20 minutes because of these conditions.

There are two trails that branch from the lookout. Each offers a about a 30-minute hike through dwarf cloud forest. The forest is dwarfed because of the acid-like rain and sulfurous gases, as well as, freezing night time temperatures. Birds, especially hummingbirds are plentiful. The landscape is dotted with beautiful wildflowers and many kinds of moss, bromeliads and ferns.

This route continues for 4-km (2 mi) and leads to nearby La Paz Waterfall Gardens. En route to these impressive waterfalls (five in total), there is a butterfly observatory which is one of the largest in the world.
