Always bring a face covering when leaving your home. Anyone over 12 years old is required to wear face coverings anytime they cannot maintain six feet of distance at OSMP trailheads and when passing others on trails. If visitors are at least 6 feet away from others, they do not need to wear a face covering over their nose and mouth. However, if visitors reach 6 feet distance to someone else on the trail, they should put the covering back over their nose and mouth. Learn more.
Limited parking on Flagstaff Mountain. Flagstaff Mountain continues to be busy on the weekends. Parking is extremely limited. For your safety & the safety of others, do not park along the side of the road. Illegally parked vehicles can be ticketed and towed. Consider visiting different locations. Plan your visits through OSMPTrails.org or download the Boulder AreaTrails App.
Siempre traigan un cobertor facial cuando salgan de su hogar. Cualquier persona mayor de 12 años requiere usar un cobertor facial cuando no pueda mantener una distancia de 6 pies (2m), ya sea en las entradas de los parques o cuando pasen a otros en el sendero. Si los visitantes están a más de 6 pies (2m) de otros, no necesitan usarlo para cubrirse la nariz y la boca. Sin embargo, si los visitantes se acercan a 6 pies (2m) o menos de distancia de alguien en el sendero, deben cubrirse la nariz y la boca.
Stay on trail and walk through mud. If needed, step off to maintain distance. Please avoid stepping on vegetation. If possible, step onto a rock or a bare spot to let others pass, then step back on the trail. Politely announce yourself if you need to pass others. Traveling off trail, whether hiking, running or biking, can permanently damage vegetation and widen trails. Learn more.
