Prusia Forest, in Irazú National Park, offers visitors the opportunity for strolls amid magnificent arboreal specimens. Follow pathways such as La Cajeta, La Cueva, and El Río and the trail called El Bajo La Laguna, which leads to the source of the majestic Reventazón River. All are a hiker’s delight. Prusia also enjoys deliciously cool temperatures year-round, which are perfect for a bit of exertion. Be sure to focus on the forest floor, home to surprises like amazing mushrooms (some as high as 16 inches) in vibrant colors that loudly declare their toxicity, so look, don’t nibble. Bundle this visit with adventures at the nearby Irazú Volcano area.
