Get up, stand up!

Altitude Paddleboards is your one stop shop for all your stand up paddleboard, river surfing, and OneWheel needs! During the COVID-19 craziness, we’ve been hard at work re-tooling our retail and shop space, as well as working on procedures to be able to operate effectively and safely once we get the all clear to get out and enjoy our beautiful state. Stay tuned for some great events happening in 2020, including our annual SUP race, grand re-opening, surf jam, and Platte River clean-up. We will also continue to provide high quality instruction at Grant Ranch, service at our store, and some other great happenings that we’ll roll out as the 2020 season shapes up.

Denver’s original SUP store

Established by John and Nancy Bridenbaugh in 2012 on Main Street in historic downtown Littleton, Altitude Paddleboards was the first SUP-dedicated retailer to open in Colorado. Summer Our shop is close to premier South Metro Denver lake and river SUP destinations, including Chatfield State Park, River Run Park (RRP) whitewater park on the Platte, Bear Creek Lake Park, Soda Lakes, and the South Platte River.

We carry both inflatable and epoxy (hard) boards covering river surfing, river SUP, and flatwater paddling. Inflatable paddleboards from Hala, Badfish, SOL, and Red. Our epoxy boards include the brands Boardworks, NSP, and Global Surf Industries. We also carry a full line of accessories including paddles, life vests (PFDs), leashes, river helmets, shin and knee pads for the river, repair products, fins, straps and rack pads, wetsuits, board bags and more.

We were also the first OneWheel retailer in Colorado, and have XRs, Pints and accessories in stock!

At our on-water location, Grant Ranch Marina, we offer rentals and classes including sunset paddles, Intro to SUP, open paddles and SUP Yoga. We can also host private groups for corporate team building events, family outings, and more. We welcome people of all backgrounds and levels. Come paddle with us!
