Costa Rica
Irazú Volcano
An acid-green crater lake at 3,432 metres where both the Caribbean and Pacific shimmer below.
The air thins and the temperature drops as the road climbs past potato fields and onion rows into grey volcanic scree. At the crater rim of Irazú Volcano, 3,432 metres above sea level, an acid-green lake shimmers in a basin 300 metres deep. On a clear morning, the Pacific and Caribbean glint simultaneously on opposite horizons — two oceans framed by a single volcanic edge in Costa Rica's Central Valley.
Irazú is the highest active volcano in Costa Rica, its main crater stretching 1,050 metres across. In 1963, the volcano began a two-year eruption that blanketed San José in ash — an event that coincided with President Kennedy's state visit and remains embedded in national memory. The drive up passes through some of the country's most productive highland farmland, where vendors sell fresh strawberries and cream from roadside stalls. The transition from verdant patchwork agriculture to barren volcanic summit happens within minutes, a jarring shift that makes the landscape feel borrowed from two different continents. The nearby city of Cartago, Costa Rica's former capital, sits at the volcano's base with its colonial Basílica de Nuestra Señora de los Ángeles.
Couple
The dramatic crater lake, two-ocean panorama, and quiet highland farmland make for a day trip that feels cinematic. Stop at roadside strawberry vendors on the way down and visit Cartago's colonial centre together.
Family
The paved road reaches the crater rim — no hiking required — making this accessible for all ages. Children are mesmerised by the alien green lake, and the farmland stops along the route break up the drive.
- At 3,432 metres, Irazú is the highest active volcano in Costa Rica — on clear days, both the Pacific and Caribbean are simultaneously visible from the crater rim.
- The main crater, 1,050m wide and 300m deep, shifts from turquoise to grey depending on volcanic activity — rangers monitor the lake colour as an indicator.
- In 1963, Irazú erupted for two consecutive years, blanketing San José in ash — the event, which coincided with JFK's visit, is still part of national memory.
- Farmland grows right to the base of the national park — the approach through potato and onion fields before a barren volcanic summit is a jarring, unique transition.
Cartago's central market serves the original chorreada — sweet corn pancake griddled on a clay comal.
The road up passes through patchwork farmland where vendors sell fresh strawberries and cream.
