Reviews of 3 week Eco Tours
- Nature's Secret Sri Lanka - 21 Days
My gratitude for the wonderful round-trip experience my family and I had in Sri Lanka. Our tour guide was amazing, and we were fortunate to have him with us. He was knowledgeable, and he provided us with insightful information about the places we visited. He was also very responsive to our questions and needs. The tour was well-organized, and the communication between your agency and us before the trip started was excellent. We appreciated the effort put in to make sure that everything went smoothly. We had the opportunity to see great nature (plants and animals), different religions and cultures, and also had time to relax by the beach. The program was well-balanced; allowing us to enjoy everything Sri Lanka has to offer. The hotels we stayed in were upper-class, and the staff was very friendly and helpful. They made us feel comfortable and welcome, which added to the overall enjoyment of our trip.Once again, thank you for providing us with a memorable experience, and we look forward to booking future trips with your agency
