My brother and I are octogenarian and have travelled extensively. A few years ago, he developed a neurological condition that limits his mobility. Serendipity Adventures prepared a private, 7-day itinerary tailor-made to Costa Rica. The tours, hotels, and response from all the staff were top-notch. Our guide Sergio made sure that every day we had an exciting and unexpected experience. We never thought that we could have gone hiking, tree climbing to have lunch on top of a 400-year-old tree, and other unusual activities. Sergio was very professional and treated us with a lot of respect and care, and was very attentive. He made sure that we were safe while enjoying our adventures. We were lucky to have found Serendipity Adventures for a once-in-a-lifetime experience. Serendipity Adventures expanded our horizons to what is possible in spite of our age. We were not able to stop talking about the trip for a long time.
