What the AVA Difference looks like

AVA Founder, Duke Bradford, found his first investor in four minutes

Man on a zipline course in Colorado.

Duke worked as a ski patroller at Keystone Resort in 1997, where he met Keith Chapeau on a lift ride up, successfully pitching his business plan in the amount of time it took to reach the top. His first investor was impressed by Duke’s idea of a guest-oriented rafting company and inspired by the business plan he wrote with only the advice of a library “how-to” book. Duke envisioned a rafting company that pushed the boundaries of just rafting. He had worked as a raft guide in West Virginia and was impressed by the level of guest service offered, with opportunities for dining and overnight stays. With this inspiration and his first investors, AVA was born out of an old camping area north of Buena Vista in the spring of 1998. AVA included only four boats, five staff, and this small facility, but the hard work of the team and its unique location allowed AVA to raft all sections of the Arkansas River, as well as offer meals and lodging.

Duke and the team took advantage of the winter and off-season to raft the Gauley River in West Virginia, as well as parts of Mexico to research and develop improvements for the company. This venture proved successful, leading AVA to extend rafting opportunities into the Gore Canyon area of the Colorado River the following summer. AVA then bought Keystone Rafting in 200, proving to be one of Colorado’s most significant whitewater rafting companies, as we continued to lead trips despite the year’s drought. Duke attributes success during this tough time period to AVA’s guides and their positive impact on the guest experience; we persevered through tough water conditions, while many other rafting companies were forced to close. Through perseverance, hard work, and a little luck, AVA continued to grow, and the young company doubled in size each year for the first five years.

2005 saw AVA’s expansion to the Clear Creek and our Idaho Springs outpost. We again doubled the number of guests in only our second year of operation here, and in 2008, AVA began to lead trips on the Upper Colorado River from Kremmling. Duke and AVA soon recognized the demand for, and importance of, additional outdoor adventure opportunities in Colorado, and expanded AVA to include a 7 line Granite zipline course near our Buena Vista outpost. This 2011 endeavor exploded, proving AVA’s competitiveness across outdoor recreation outfitters, and allowed us to add our 6-line Idaho Springs course in 2012. 2011 additionally distinguished itself as an important year, as we expanded into the transportation sector with the implementation of our shuttle services and transportation company, Peak 1 Express. Peak 1 Express increased transportation opportunities within the mountains, and thus access to Colorado’s great outdoors and outdoor recreation opportunities.

In 2016, AVA expanded our Upper Colorado River services to include Fishing trips and UTV and equipment rentals and opened an outpost in the Kremmling area to better service rafting on the Colorado River. 2017 and 2018 additionally saw increased recreation opportunities, as we built exciting Via Ferrata courses at our Idaho Springs and Buena Vista outposts. Duke and all of us at AVA are proud of all that we have accomplished since 1998 and look forward to developing new and thrilling outdoor adventure opportunities for our guests. We seek to embrace the possibilities within the outdoor recreation field, while remaining true to our roots in guest service and low-impact recreation.

Even as AVA continues to grow and expand, Duke remains committed to sustainability efforts regarding natural resources, river access and water quality, fighting to protect the rivers that have and will continue to provide us opportunities for adventure, connection, and excitement.

I took my husband and our three children ages 17, 13, and 12 and we had the experience of a lifetime. Parker was our guide and he was knowledgeable and professional, and has the best personality for what he’s doing. We booked the Browns Canyon Sizzler and we could not have been happier with our choice. We embarked on our adventure around 9am and were back at the outpost mid afternoon. Halfway through our float we stopped and had delicious fajitas prepared right there by the river by the guides. I’m so glad I decided to go with this company, we were not disappointed one bit. We definitely have AVA in mind the next time we come to Colorado, maybe I’ll try some zip-lining next time. Thanks for the awesome adventure!

Browns Canyon is beautiful and the rafting is great for families, but please choose any other outfitter besides AVA. Our party of 12 experienced an organizational clownshow yesterday, and an indifferent admin that seemed unable or unwilling to make it better when their mistakes kept piling on. Our summer sizzler trip started with the van not having functional seat belts. After a few miles in the van, we RAN OUT OF GAS. We waited about 15 minutes by the side of a busy highway in the hot sun (in wet suits and PFDs!) while the hapless guides tried to run up the road until they could get a cell signal. When the rescue van came, we couldn't use it because it had BAD BRAKES. The 3rd van that came worked, but it also lacked seat belts.
[ These same crappy vans are also used by Peak 1 Transportation in the winter to Breckenridge, so avoid them too. ] If this is a company that puts "safety first," as I was told, nobody mentioned that to their van mechanics.
We were excited about the planned riverside hot lunch of grilled fajitas. After we pulled out at Hecla junction, the guides started to make lunch...and then stopped. I heard a few reasons why, but the story kept changing. We ended up not getting lunch until back at the office at 3 pm. Even with our late arrival, they still didn't have our trip pictures ready.
They didn't meet us with food or apologies. They didn't seem too concerned about the cascading series of logistical fiascos, even though the office staff knew all about it and pledged to help when I asked to speak with a manager. They weren't authorized to do any refunds, and the back office guy who could didn't call me back for over 24 hours and then made only very weak attempts to make things right.
I'm giving 2 stars instead of one because the guides were good, the river and rapids were beautiful, and we saw some great wildlife, but you should choose any of the dozens of other outfitters running this river.
