The volcano formed 7,000 years ago from the adjacent (and now extinct) Chato Volcano, Arenal’s most recent eruptive period began in 1968 with an explosion that buried three small villages and left 87 people dead. It was active with almost daily effusion of smoke and lava until July 2010. The area that surrounds the volcano is home to a number of hot springs, thanks to the geothermal activity beneath Arenal. Arenal is the most famous volcano in Costa Rica, but it’s not the only one. The country hosts six active volcanoes and sixty dormant or extinct volcanoes within its borders.
There are quite a few places to hike around the volcano, The 1968 Trail, the Arenal Volcano National Park and Arenal Observatory Lodge. We decided to spend the day at the lodge since it offers a variety of trails through the tropical rainforest, primary and secondary forests, pasturelands and manicured gardens. In our five mile hike we had a chance to see three waterfalls, tons of flora, lots of tropical birds and even a snake. But we still haven't seen the top of Arenal Volcano or a monkey.

The lodge has a large bird feeder near the deck. It was a lot of fun seeing all the different birds.
