Costa Rica has over 200 volcanos with some more accessible than others. Poas Volcano & National Park is one of the most visited in the country and for good reason. On a clear day you can see both craters. A short 20-30 minute hike and you are at the second crater. Las Maravillas Volcano is quite unique as you can walk inside the crater seeing the bubbling mud pots. Here you can lather with the volcano mud which is great for your skin and use the fountain pools to relax. By horseback or tractor ride to the top of the mountain you can walk across the hanging bridges, swim in the waterfalls and take in the breathtaking views. Within in 20 minutes you have change from one eco system to another. In Guanacaste relax in one of the countries hot springs, see the cone shape Arenal Volcano which is now dormant, venture into the town of La Fortuna for a little shopping, or enjoy the hanging bridges located about 1 hour from Arenal. Rincon de la Vieja area has the Rincon de la Vieja National Park & volcano, enjoying tubing on the river, canyoning for the adventurist, or a nature hike.
