Great Tour Guides! - I did two tours with Go Adventures while in Costa Rica, and both were excellent. First I did the zip line & rappelling tour, and the guides were super friendly and entertaining. They were high energy and their outgoing personalities made the tour especially enjoyable. The tour lasted about 2 hours and ended at the Arenal river so wear a bathing suit if you want to take a dip. The second tour was a full-day tour of Arenal volcano, La Fortuna Waterfall & the hanging Bridges with Monica. She was like a walking encyclopedia. Monica was extremely knowledgeable and also very sweet. Afterward, everywhere we went I said, “I wish Monica was here” so she could offer explanations to me. At the end, I felt like I was back in school - I had learned so much. I can’t recommend the tours enough. I’m just sad I didn’t get to do the running tour with Go Adventures.
