Rocky Mountain Paddleboard offers friendly, well-equipped paddleboard and kayak rentals on Longmont’s Union Reservoir. Experience accessible water recreation, dog-friendly boards, and special events just outside Denver.
Book your paddleboard early, especially on weekends, to avoid wait times at the reservoir entrance.
Union Reservoir can get busy midday; opt for mornings or late afternoons for calmer waters and fewer crowds.
Colorado’s sun can be intense, so pack sunscreen, a hat, and plenty of water to stay hydrated.
Dogs are welcome on paddleboards but should be leashed until on the water for safety.
Union Reservoir was constructed for irrigation and flood control but has become a prime local recreation spot since mid-20th century.
Visitors are encouraged to follow Leave No Trace principles to keep the reservoir and surrounding habitat pristine.
Safety-first: a properly fitted life jacket is required for all paddlers.
Protect your feet from rocky shores and keep grip on wet boards.
