“This was our first time rafting and we couldn't have had a better experience! We had sooo much fun! Awesome guide, extremely knowledgeable and explained everything in advance.”
“So much fun! Really awesome guides, and super knowledge of the river!”
“Bought as a Father's Day gift and it did not disappoint. Adam gave us a top notch experience from start to finish. We plan to make this an annual adventure. Would highly recommend!!!”
“We had a phenomenal time with Adam! He is very knowledgeable of the river, a powerhouse on the back of the boat, funny and made us feel confident going through the rapids. Lisa was friendly, helpful, and had some awesome driving skills! We really appreciated the personalized service that you might not get with the bigger companies. Thank you, and see you at the beginning of next season!”
“This is our second trip with Monumental Expeditions and it was just as great as the first time! Adam and Lisa were great at communicating, keeping everyone safe, and making sure we all had a great trip. Would definitely recommend you book with Monumental for Brown's Canyon or any of their other trips!”
