The main driveway car park will be closed from noon daily until September 30 due to flash flood risks.
Boulder County, Colorado. Corral, Main, and associated trails will reopen Thursday, June 16, following extensive recovery efforts from the Cal-Wood fire in October 2020.
Parks and Open Space employees had hoped to open in time for Memorial Day weekend, but delivery of materials was delayed. The majority of the park’s infrastructure will be restored by the June 16 opening date, but some final projects will be completed after the park opens.
Fire damage requiring extensive repair and recovery included hazard tree removal, aerial coverage, erosion and debris loosening, and replacement of damaged visitor amenities and park infrastructure including bridges, fencing, parking, and signage. Please visit the Heil Valley Ranch Recovery webpage for more information.
The main road is closed from noon daily until September 30
During the common heavy rain in the summer, the heavily scorched landscape is likely to flood all the small and large canyons and deposit debris and mud in the downstream/slope areas, including the main road. The Main Trailhead car park will be closed from noon daily until September 30 due to flash flooding safety concerns.
The car park is located in a drainage area between Khalideen and is prone to flash floods as a result of the alteration of the landscape caused by the Cal Wood fire. Tickets will be issued to all vehicles still in parking in the afternoon. Walkways, picnic tables, and shelter will remain open until sunset, but visitors must park elsewhere.

Wapiti Trail Detour
A section of the Wapiti Trail will remain closed to protect Golden Eagles. A resident vulture pair built a nest in the Wapiti Trail during lockdown. They had a successful brood last year and are actively living again this year. Please follow the detour along the emergency access road.
The inflection will be in place year-round for the next several years to allow for monitoring of nest activity. Boulder County is working with the Colorado Parks and Wildlife Service and the US Fish and Wildlife Service to ensure that sensitive species are protected. Staff follow federal guidelines, such as the Bald and Golden Eagle Protection Act, and detours allow a half-mile buffer zone between the nest site and areas of human activity.
