Getting into the Water
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.
