I never tire of watching red lava rocks tumble down the flanks of Arenal Volcano and listening in awe to its deep rumbling. If you've never experienced them firsthand, the sights and sounds of an active volcano are awesome. Arenal is one of the world's most regularly active volcanoes. In July 1968, the volcano, which had lain dormant for hundreds of years, surprised everybody by erupting with sudden violence. The nearby village of Tabacón was destroyed, and nearly 80 of its inhabitants were killed. Since that eruption, 1,607m (5,271-ft.) Arenal has been Costa Rica's most active volcano. Frequent powerful explosions send cascades of red-hot lava rocks down the volcano's steep slopes. During the day these lava flows smoke and rumble. However, at night the volcano puts on its most mesmerizing show. If you are lucky enough to be here on a clear and active night -- not necessarily a guaranteed occurrence -- you'll see the night sky turned red by lava spewing from Arenal's crater. In the past few years, the forests to the south of the volcano have been declared Arenal National Park. Eventually, this park should stretch all the way to Monteverde Biological Cloud Forest Reserve.
Lying at the eastern foot of this natural spectacle is the tiny farming community of La Fortuna. In recent years this town has become a magnet for volcano watchers from around the world. A host of moderately priced hotels are in and near La Fortuna, and from here you can arrange night tours to the best volcano-viewing spots, which are 17km (11 miles) away on the western slope, on the road to and beyond the Tabacón Grand Spa Thermal Resort.
