Centennial Park Trailhead
People enjoy open space for physical, emotional and mental health. Remember to always be courteous. Don't forget to:
- Plan visits ahead of time and don’t park illegally at full trailhead areas.
- Remember to “keep the space in open space.” Maintain 6 feet of distance from people not in your household.
- Leave No Trace. Stay on trail and walk through mud. If you step off trail to let others pass, immediately step back on trail.
- Protect first responders. Know your limits and don’t take unnecessary risks.
- Visit OSMPTrails.org to see current trail closures, historical data that shows areas of high and low open space use and trails that are wider than 6 feet. See when trails are busiest through our Visitation Data Explorer.

Parking - Know the Facts
It is unsafe and illegal to park in a way that:
- Blocks emergency access gate or fire lane
- Blocks pedestrian gate or driveway
- Prevents horse trailer parking
- Along any highway or a roadway where prohibited by sign
All vehicles parked in a manner described above are subject to being ticketed/towed.
Never park in the roadway.
The roadway is defined as the space between the white (fog) line and the yellow (center) line. If ANY part of your vehicle (tire, mirror) is between the white and yellow lines, your vehicle is a hazard and can be ticketed/towed immediately.
Because parking is very limited and our trailheads are quite popular, please show up early to get a parking spot.
Please keep your car doors locked and your car windows rolled up at all times while leaving your vehicle parked at OSMP trailheads. Also consider leaving important valuables at home or take them with you while visiting open space. To report suspicious activity please call City of Boulder Dispatch 303-441-3333 or Boulder County Dispatch 303-441-4444. For crimes in progress, call 911 immediately.
Red Rocks Trail is 0.5 mi; 300ft. This area is actually a network of short trails. Starting at Centennial Trailhead the trail gains a ridge. It goes to the saddle to the right of the spectacular fins of Red Rocks. The trail continues down the ridge to end at Settler's Park. The Sunshine Canyon Trail (1.3 mi) branches off from the Red Rocks Trail just after going over the Silver Lake Ditch and heads west up Sunshine Canyon. The Anemone Trail (0.4 mi) branches off from the Red Rocks Trail 0.2 mi from the trailhead and goes up Anemone Hill.
Across Sunshine Canyon Drive from the Centennial Trailhead is the access point to Mt. Sanitas.

Black bears, mountain lions, and mule deer are inhibits to this area.
Settlers' Park got its name because it was thought to be the location of the first permanent camp of American settlers in the Boulder area. The group pitched their tents at the base of the sheltering Red Rocks on Oct. 17, 1858. A group of about 24 men heading toward Cherry Creek-Auraria gold strikes broke away from their wagon train because one of their members, Captain Thomas Aikins, thought that the "mountain looked right for gold" in the foothills west of the Boulder area. Red Rocks was purchased in 1920 and 1926.
