It isn't every day that you can watch a live lava flow from your hotel window and sleep, literally, at the foot of an active volcano. Costa Rica's Arenal Volcano is one of the world's most active volcanoes, with eruptions occurring daily. Adventure travelers will see huge plumes of ash shooting upward and hear giant lava rocks cascading down the sides of its ominous slopes. Travelers can hike 2.8 km uphill to reach the Arenal Observatory where there is a cozy lodge perched high on one of the volcano's ridges. This is truly a once-in-a-lifetime adventure. You can find out more information by visiting the Arenal Observatory Lodge website at http://www.arenalobservatorylodge.com.
