Costa Rica has six active volcanoes and 61 that are either extinct, or dormant. Going back over the last five decades, Arenal happened to be the countries most active volcano. While the Arenal volcano went into a resting phase in the year 2010, (which means that it’s done erupting at the present moment) it’s still a top tourist attraction and the most visited volcano in Costa Rica. I’ve visited it many times, and we had our wedding at The Springs Resort near there, so it’s a special place for us! Today I’ll talk about the volcanic activity in Costa Rica, as well as highlight the ones that are worth exploring.

Volcanoes in Costa Rica

  • Costa Rica, part of the Pacific Ring of Fire, is home to six active volcanoes that enrich soil, support lush rainforests, and offer unique visitor experiences including hiking, wildlife encounters, and relaxing in hot springs.

Located on the seismically vibrant Pacific Ring of Fire, Costa Rica boasts a landscape dotted with six active volcanoes that have been instrumental in shaping its current geographical features. Nestled mainly in the Central Highlands and northern parts of the country, these colossal natural structures have continuously erupted for upwards of 75 million years. Their eruptions have deposited mineral-rich substances across the land, fostering dense rainforest growth. An active volcano in this context is one that has experienced an eruption within recent geological memory—specifically within the past 10 millennia—and by this classification, Costa Rica’s roster includes:

  1. Arenal Volcano
  2. Poás Volcano
  3. Irazú Volcano
  4. Turrialba Volcano
  5. Rincón de la Vieja Volcano
  6. Miravalles Volcano

Embarking upon Costa Rica’s volcanic terrains opens up a treasure trove of singular encounters and vistas.

  • envision yourself perched at a crater’s edge, peering into its seemingly endless abyss as tendrils of smoke ascend toward clear skies.
  • traverse lush pathways filled with wildlife sounds which then lead to desolate areas where once-molten rock stands frozen amidst ash-covered grounds.
  • take pleasure from sweeping views mixed with exhilarating activities or bask serenely in soothing thermal springs.

The allure emanates from not just any volcano, but specifically those magnificent sites classed as ‘Costa Rica volcano’, heralding realms ripe for adventure and discovery.
