Park Location

Boulder Reservoir is located at 5565 N. 51st St. in beautiful Boulder, Colorado. Once you enter the park, follow the main road to the boathouse/marina. We are located in the orange boathouse building near the main boat ramp.

**If you want to bring your own board you must already have a small craft permit for Boulder Reservoir. They are sold out for the year, so if you do not already have one you can not bring your own board.

Can My Pup Paddle Too?

Although we love your dog, they are not allowed in the park from May 15 to Labor Day.

When Nature Calls…

Restrooms are conveniently located at the back of our shop (because sometimes, nature calls before you hit the water!)

Didn’t Bring Lunch?

Grab a snack or drink on site! For tastier options, visit our Lakeside Cafe inside the Visitor Center.
