Guanadreams CR is a family-run, local operator of private nature tours in Guanacaste, Costa Rica, founded in 2014 by Miller Contreras Canales and Karol Murillo Portilla and based in Playas del Coco. We are not a booking agency: we run what we sell and guide it ourselves — private days with a naturalist guide, from the Papagayo coast to the Tenorio rainforest, with hotel pickup and 300+ five-star reviews.
Guanadreams is not a booking agency and never has been. We started it in 2014 because most of what was being sold to visitors on this coast was bought from someone else, run by someone else, and explained by nobody. We kept it small on purpose: we run what we sell, and we guide it ourselves.
We are Miller Contreras Canales and Karol Murillo Portilla — the two pillars, and the two hearts, behind Guanadreams CR. Together we've built a company rooted in one shared devotion: a deep love for Costa Rica's nature and a commitment to protecting it.
Our stories began in very different places, but led us to exactly the same one.
Miller was born and raised right here on the shores of Papagayo, at Playas del Coco, in his grandparents' home — facing the beach, surrounded by nothing but nature. That's where it all began. As a small child, watching the birds around the house and along the shore, he fell in love with wildlife. The birds pulled him into a lifelong fascination with nature and, above all, with caring for it — a passion that never left.
Growing up in one of the most visited regions of Costa Rica, surrounded by travelers from the United States and Canada, Miller learned English the way many of us here did — from the visitors themselves. For over 30 years he has worked in every corner of Costa Rica's tourism industry — luxury resorts, property management, and concierge work on the Peninsula Papagayo — and for over 20 years as a naturalist guide. He has traveled nearly all of Costa Rica in search of its hidden pockets of wildlife, building a knowledge of our country few can match. For Miller, nature and photography aren't a job. They're how he breathes.
Karol comes from Costa Rica's Central Valley, near San José. An entrepreneur and a pharmacist by profession, she felt an even stronger pull toward nature — so strong that she left the city behind and moved to Guanacaste, following her love for the natural world. When she and Miller met, it was a perfect match: two people on exactly the same page, devoted to the same mission.
Ten years ago, Karol joined Miller full-time to build something stronger together. Today, Miller is the one in the field, guiding — and Karol is the foundation that holds everything together. And we never stop learning: we continually train and educate ourselves to understand more, every single day, about Costa Rica's nature and environment. Because we carry a real responsibility — to teach the world, and every traveler who visits us, how to cherish and protect it. That is our clearest purpose, alongside the goal we set for ourselves: to give our guests the finest experience of their lives.
We founded what has become Guanadreams CR, formerly known as Guanacaste Dreams Vacations. We work alongside a team of highly qualified, certified naturalist guides — each carefully trained in our own principles: the same conservation ethics, the same respect for nature, and the same standard of care for every guest.
We're not a company that simply sells tours. We craft private, personalized experiences, built around what each traveler dreams of — always within a framework of respect for the natural world. Our greatest goal is that you leave Costa Rica with the finest experience possible, and carry home a small seed of something bigger: how to protect our planet, how to care for nature. That's what Costa Rica strives to teach the world — and we're proud to be part of it.
We don't just show you nature; we teach how to respect and live alongside it.
No crowded buses, no fixed scripts. Every experience is yours alone, customized to what you want.
This isn't work for us. We love photography, we love wildlife, we love this land. It's how we de-stress, how we live.
