Tubing, Kayaking, Rafting, and River boarding on Boulder Creek
The St. Vrain Creek in Longmont is open to all uses from the western City limits (at Airport Road) to Boston Avenue. This includes entering, remaining in, floating or using non-motorized watercraft.
The creek is closed to ALL uses between Boston Avenue and Main Street due to construction activity related to the [Resilient St. Vrain (https://www.longmontcolorado.gov/departments/departments-n-z/water/stormwater-drainage/resilient-st-vrain) project. This closure applies to entering, remaining in, floating or using watercraft in this reach.
The St. Vrain Creek east of Main Street to 119th Street is open to public use. View the Frequently Asked Questions below for more details on the float course.
A new float course (also referred to as a tubing course or kayak course) was created during the creek channel work on the Resilient St. Vrain project. The course is made up of 9 smaller rock fall areas that help keep water (and floaters) moving downstream. This course can accommodate tubes, kayaks or small boats (non-motorized only).
Enter the float course at the designated open water access point east of Main Street. Exit the course at designated takeout points east of Martin Street or at the 119th Street trailhead. The access and takeout points are designated by signs.
During May and June the water is typically pretty cold. When the water is over 300 cfs, it’s usually in peak snow melt time. That means, you guessed it, cold water. We rent wetsuits. The water usually starts warming up when the snowmelt is winding down.
40cfs to 400cfs is a good flow for tubing the Saint Vrain River in Longmont, Co.
