This comprehensive guide will help you navigate Arenal Volcano National Park and the surrounding La Fortuna area, offering insights into its best hikes, rejuvenating hot springs, and thrilling activities.

Why Visit Arenal Volcano National Park?

Arenal is more than just a volcano; it's a dynamic region teeming with natural wonders and adrenaline-pumping adventures. Once one of the most active volcanoes in Costa Rica, Arenal now offers a more serene but equally captivating experience, drawing visitors with its iconic conical shape, diverse ecosystems, and the therapeutic allure of geothermal hot springs. From exploring ancient lava flows to spotting incredible wildlife, Arenal promises an unforgettable Costa Rican journey.

Exploring the Trails: Hiking in Arenal Volcano National Park

The national park itself offers several well-maintained trails that provide excellent views of the volcano, Lake Arenal, and the surrounding rainforest. While you cannot hike to the summit for safety reasons, these trails offer fantastic opportunities to get up close to historical lava flows and discover the area's rich biodiversity.

Popular Hiking Trails

Best Time to Visit Arenal

  • Book in Advance:Especially during peak season, popular tours and accommodations in La Fortuna can fill up quickly.
  • Stay Hydrated:The tropical climate can be demanding, so drink plenty of water.
  • Combine Destinations:Arenal pairs perfectly with a visit to the cloud forests of Monteverde Cloud Forest Biological Preserve or the beaches of Santa Teresa Beach or Jaco Beach for a diverse Costa Rican itinerary. Consider other volcano experiences like Poás Volcano as well.
