The hoover dam kayaking tour was great. No problems at all- the entire trip was smooth and efficient. We paddled the entire day, hiked to the hot spring and more paddling and hiking! Our tour guy, Alex was excellent. He is very knowledgeable, friendly and helped us take pictures along the way. We had Mcdonalds breakfast and some Arby's sandwiches, grapes, crackers for lunch; and an abundant supply of water during the entire trip. Very enjoyable!
