Union Reservoir

Entry Fee

Please plan on a park entry fee of $10/vehicle on weekdays, $12/vehicle weekends.

Long line? Head to Barefoot Lakes instead!

Park Location

Union Reservoir is located at 461 CR 26 in Longmont, Colorado. CR26 is located 1/2 mile North of 119 on East County Line Road. Please ignore directions that take you to the backside of the reservoir or to the sailing club. Once you enter the main gate, we are located in the blue building right across the grass picnic area.

Can My Pup Paddle Too?

Pups are encouraged to join the adventure! Bring your four-legged first mate on any of our watercraft and let them enjoy the ride (just don’t let them steer!)

If they need a little extra safety, we’ve got dog lifejackets available on a first-come, first-served basis.

When Nature Calls…

Restrooms are conveniently located on the way to the swim beach (because sometimes, nature calls before you hit the water!)

Didn’t Bring Lunch?

Grab a snack or drink on site!
