What a great adventure! My husband and I took the Black Canyon kayak day trip and had a blast! Scheduling the trip was a breeze, the crew was on time and organized when launching. Our guide, Regina, was personable, funny, capable, and very knowledgeable in wilderness and history. The sites were fantastic! Launching from the secure side of Hoover Dam was a treat! The slot canyon stops with mini hikes were a great way to learn and see about the diverse ecological systems along the Colorado. We saw mountain goats along the way, too! Lunch was hearty and healthy which was a nice surprise. The Emerald Cave and historic site views were so enjoyable! The water was great and it was simply a perfect way to see the beauty of the mountains! I would recommend going on a Sunday when there is little motor boat traffic. It's worth it especially if you aren't an avid kayaker. Plus, it makes you feel like you have the river and canyons all to yourself. So peaceful! The 12 mile kayaking was a challenge at times. The wind can really be your friend or foe depending on its direction and strength. I wouldn't plan much for that night ... We were sore! But, the next day - felt great! Overall, I'd highly recommend this trip! The value for the cost is tremendous!
