Intrepid are an excellent company to book with for adventurous trips, they are extremely good at what they do, they also have very good choices of where and when to travel around the world. I would not hesitate to recommend them to other travellers.
Although we have been to many countries (70), this was our first group trip. We greatly enjoyed it. Marial (our group leader) was fantastic and so were the other people in our group (12 of us travelers in total). Having had such a good time on this trip, we are open to doing another one!
