7 Essential Adventures in Costa Rica's Arenal Region From Volcano Hikes to Hidden Hot Springs - Hiking the Ancient Lava Trails at Arenal Volcano National Park

Arenal Volcano National Park, found in the La Fortuna area of Costa Rica, safeguards 16 different reserves within its borders. The park features two volcanoes: Arenal, which has been active in the past and is now resting, along with Chato, which is smaller and inactive. Trails within the main Sector Volcan are more frequented while the less traveled Sector Peninsula borders Lake Arenal. The Arenal 1968 Trail allows visitors to get close views of old lava flows. Hikers can choose from paths such as Heliconias, Los Miradores, and El Ceibo, with each trail around 2 to 3 kilometers in length. Established in 1991, the park aims to protect the diverse area's ecosystems. Besides hiking, it is possible to enjoy activities like horse riding and visiting waterfalls, along with a variety of hot springs in the region. The park welcomes visitors daily from 8:00 AM to 4:00 PM with last entry at 2:30 PM. Lake Arenal, the largest lake in the country, sits next to the park and hosts varied wildlife and scenic vistas.

The Arenal Volcano, a 1,670-meter peak, offers more than just a picturesque backdrop; it's a geological timeline. Its last major eruption was in 2010, turning hikes along its solidified lava trails into a walk through the recent past. These trails, composed of basalt and other volcanic rock, expose formations shaped by both the violent forces of the volcano and the subsequent impact on surrounding life. One observes "tree islands" – small, forested areas thriving on the old lava flows, a showcase of resilience and ecological recovery in harsh volcanic landscapes.

The thermal activity around the Arenal is impressive, driving local hot springs, some reaching extreme temperatures due to magma proximity just below the surface. This volcanic fertility is not just hot springs though, it's the foundation for lush biodiversity. It's the foundation for agricultural practices, such as coffee and fruit production, highlighting geology's direct impact on daily life. Different lava flows exhibit textures based on their cooling properties. The 'pahoehoe' lava with its smooth, ropy surface, is a good visual lesson in molten rock dynamics.

Arenal's trails act as both learning tools and wildlife hubs. The microhabitats host over 850 bird species. Certain lava trails are surprisingly young – some are the result of the 1968 eruption demonstrating how rapidly volcanic landscapes can be reshaped, rather unexpectedly. The trails have been constructed with thoughtful engineering, prioritising visitor safety while educating the visitor about surrounding hazards. For the careful observer, fumaroles provide a view into Earth's dynamic interior, with steam and gasses emanating from the volcanically active zones.
