We had a very enjoyable and informative tour. Our guide- Richard was great!! Thanks
BAIT AND SWITCH! Do not go! If you go and you have more than twelve people then ask for a refund! Advertised small tour of 12 or less turned into tour for 27, all crammed into a small bus with seats smaller than airline seats and no storage. The driver said they use buses all the time, which is contrary to their published description. Our guide, Sergio, was unskilled: Lunch was not until 2:30 with an additional wait time of 30 minutes Sergio would not use the bus microphone although many people kept asking him to use it, so only people up close could hear him again and again Sergio would declare a 15 minute stop and them not return until 45 minutes had passed he went in reverse order of the listed tour and our last stop at the overlook was closed by the time we arrived. An eight hour tour turned into twelve hours of misery and disappointment. Viator was helpful when I complained and they issued a full refund, which helped, but it was still a waste of an entire vacation day. I have used Viator many times for touring, this is the first time a tour was unsatisfactory. Viator's customer service was excellent.
