I was lucky enough to have a 2 day paddle down the Colorado River through Desert Adventures and it was awesome. We didn't have a guide, as I was with some students and our professor had done the trip a million times. He has rented through Desert Adventures for years. The price was great, we were picked up on time from our hotel at Lake Mead, and our driver was hilarious. We were entertained for the entire ride, and he was filled with fun stories and facts about the area. Being dropped off at the base of Hoover Dam was pretty wicked. The canoes were nice and sturdy, and large enough for all of our camping gear. Camping at the hot springs was SO cool. If you're going to the area, you HAVE to do a canoe trip. I'll definitely go through Desert Adventures again when I go back. Thanks guys!
