Our guide was so knowledgeable about the flora and fauna as well as the history and current conditions of Costa Rica and surrounding countries. Learning is so much a part of what we want to experience while traveling. This was an excellent opportunity. A bonus is how absolutely gorgeous Costa Rica is.

We just returned from the Costa Rica Eco-Adventure (2/1/2025-2/8/2025). This was our sixth Trafalgar trip. was a WONDERFUL tour guide. Very knowledgeable and personable. worked very hard; it was much appreciated! It was a great tour! A couple of things we noticed on this trip, that were different than previous Trafalgar trips . . . We prepaid our gratuities (as we always do). Usually, the tour guide talks about the ability to tip the guides and drivers, and thanks those who have already paid the gratuity. This didn't happen on this trip. We hope he received our prepaid gratuity! Also, on previous trips, it was noted if you had been a previous Trafalgar traveler. This did not happen on this trip. We are proud Trafalgar trip repeaters, which makes us some of your greatest advertisers. One suggestion we had: For our farewell dinner, we went to a restaurant where we could order off the menu. There were 42 of us. It took probably two hours to get our food. It would be better to limit the menu to a couple of appetizers, salads, main entrees and desserts, to make the evening not as long. Thanks again for a wonderful experience. We will be back to travel with Trafalgar again!

My trip was wonderful -- I can't say enough good things about Mario and his team! I was travelling solo, and they worked with me to customize the itinerary to be exactly what I needed alongside a work trip I had right before. All of the guides and other staff members were very professional, kind, and prepared. Pickups were on time, and even mundane drives were filled with interesting information and good conversation. Special shoutout to Alberto, who took me to Tortuguero and was so knowledgeable about wildlife (and whose keen eyes spotted some spider monkeys on the drive home, enabling us to stop and see them and some howler monkeys). A true highlight! But everyone was wonderful -- definitely recommend.

I booked this trip for my daughter and me. She wanted action and adventure, every day, and this trip delivered. I was pleasantly surprised by the quality of the hotels. Much nicer than I expected, given the low cost of this to her. Most of the transportation was fairly high-quality as well. The bus too, and from the rafting was nothing fancy, but certainly nothing to worry about. Be prepared to spend a little more time than you might expect in transit. That's a function of Costa Rican infrastructure. Lots of one lane roads means travel between cities can be really slow. But the scenery is gorgeous. If you just consider it part of the adventure, and enjoy it, it's not a problem. I highly recommend this trip. It had everything we wanted.

We loved the La Paz Waterfall Gardens and Sarapiqui River tour! La Paz is beyond beautiful with orchids, hummingbirds, frogs, toucans, scarlet macaws, parrots, coatis, sloths, ocelots, margays, and a jaguar. The gardens and waterfalls are exquisite. A wonderful buffet lunch was included. Our trip down the Sarapiqui River in a covered boat was so much fun! We saw two caimans, iguanas, Anhingas, swallows, butterflies, and five troops of Mantled Howler monkeys. Oscar and Armando, our guide and driver were so kind and taught us so much. We stopped at a lovely coffee finca to see the beans ripening, a sopa (local restaurant) in the mountains to take in spectacular waterfall and hummingbird views, we watched whitewater rafters, and sampled fresh pineapple at a farmstand. Oscar and Armando treated us like family and made our first day in Costa Rica amazing!
