If Timber Creek Campground in Rocky Mountain National Park is your go-to base on the quieter west side of the park, late-summer plans for 2026 will need a rethink.
The National Park Service says Timber Creek will close for the season at noon on August 10, 2026. This cuts the camping season short so crews can complete a long-planned sewer system rehabilitation project. After it closes, the Park Service expects the campground to remain shut for the rest of the year and reopen for the 2027 season.
Why the campground is closing early
According to the Park Service, the work involves repairing aging sewer lines and deteriorating manholes. They’ll be using modern pipe-lining techniques. It is not the kind of infrastructure most campers ever notice. But it is still critical to keeping the campground operating safely and reliably in the years ahead.
Timber Creek itself is not a new campground. Parts of it date back to the late 1930s, when Civilian Conservation Corps crews built several of the original comfort stations that still stand today. While the Park Service has not said when crews installed or last upgraded the sewer system, officials describe the infrastructure as aging. That prompted the need for a full rehabilitation now rather than piecemeal repairs later.
What makes Timber Creek different
Timber Creek is the only campground on the park’s west side. That alone gives it a different feel. The campground’s four loops line the Colorado River at roughly 8,900 feet and typically offer cooler temperatures, more shade, and fewer crowds than the Estes Park side of the park.
Elk and mule deer are common sights, and many campers choose Timber Creek specifically for its quieter atmosphere and easy access to Trail Ridge Road and west-side hikes.
That is also why the early closure matters. Late summer and early fall are popular times for repeat visitors who want to avoid peak-season crowds.
Where campers can go instead
Campers planning to stay in Rocky Mountain National Park after August 10, 2026, will need to look to east-side campgrounds. Think of Moraine Park, Glacier Basin, and Aspenglen, which are expected to follow their usual seasonal schedules.
Reservations for all park campgrounds are handled through Recreation.gov and typically open six months in advance.
The inconvenience is real. But if the repairs do what they are supposed to do, Timber Creek should reopen in 2027 ready for many more quiet west-side seasons.
