This community has been home on Calle Mariposa in Playa Potrero, Guanacaste since 2018. Despite pandemics, floods, and massive changes in the region, we’re still going strong as a proud part of the Guanacaste fitness culture.
Today, CrossFit Potrero stands as an inclusive community where locals and travelers alike come together to train. Our open-air box is more than just a gym; it’s a place to connect with friends, enjoy nature, challenge yourself, and work towards lifelong health.
So whether you live here in Guanacaste, or are on vacation and want to keep up with your routine, we'd love to host you here under the mango trees.

Our coaches are at the heart of the CrossFit Potrero community, offering high-level instruction and thoughtful support through every aspect of your lifelong fitness journey.
Whether you're just getting started, rehabbing a long-term injury, improving your mobility, craving the next level of fitness, or seeking to hone your craft to the highest level, you can count on our coaches to get you there.
