Arenal is one of the most active Volcanoes in the world, and certainly the most active in Costa Rica. Its almost perfectly conical shape grows approximately 12 feet per year due to the constant emanation and accumulation of material. Since the resumption of its activity it has grown over 720 feet and it currently stand at 5436 feet above sea level.
For the best observation of continuous explosive activity accompanied by slow lava effusion and the occasional emission of pyroclastic flows, we recommend observation from Mirador Arenal 1968.
