Something amazing about our country is the enormous variety of volcanoes that we have. Many of them active, though easy to visit. In most cases they are protected areas or national parks. So, in several volcanoes there are roads that take you right to the crater and in Arenal, for example, the area is surrounded by great hotels, not to mention the incredible lake.
A must see while you are in the area is the Tabacon hot springs which is also a luxury hotel. At night, the natural light effects of the volcano are amazing. However for the Central Valley volcanoes, we recommend to get up early and beat the clouds, with time to see the craters and the surrounding scenes.
Getting there is half the fun. One can stop for breakfast, buy crafts or enjoy the trip. In some cases, cozy mountain hotels spread over the hills.
