Geography and Location

• Location: Arenal Volcano National Park is located about 3 hours north of San José, the capital of Costa Rica. The park is situated near the town of La Fortuna, which serves as the main entry point for visitors. The park encompasses the Arenal Volcano, a dormant stratovolcano that rises to an elevation of 1,670 meters (5,476 feet) above sea level, and stretches into the surrounding rainforest and Lake Arenal.
• Topography: The landscape of the park is marked by dramatic contrasts, with the Arenal Volcano towering above the landscape, surrounded by lush lowland rainforests, volcanic rocks, and lava fields from past eruptions. The park also includes portions of Lake Arenal, offering opportunities for water activities such as kayaking and fishing.

Arenal Volcano

The Arenal Volcano is the centerpiece of the park and one of Costa Rica's most active volcanoes. For much of the 20th century, the volcano was in almost continuous eruption, spewing ash, lava, and gases. However, in 2010, it entered a resting phase, and its eruptions have significantly decreased. Despite this, Arenal remains an iconic symbol of Costa Rica's geological activity and is still an impressive sight, especially when viewed from the surrounding park and town.

• Last Eruptions: Arenal's last major eruption occurred in 1968, which resulted in significant lava flows and a volcanic explosion that caused the destruction of nearby settlements. Since then, the volcano has been continuously active, but its eruptions have been smaller and less destructive.
• Current Activity: While the volcano is no longer as active, the surrounding area remains a hub for geothermal activity, with numerous hot springs and fumaroles (steam vents) present in the region.
