Colorado will celebrate the state's birthday by offering free entrance to all 42 state parks on Monday.
Free entrance to state parks is a Colorado Day tradition. The legislature created Colorado Day to mark the anniversary of statehood, granted in 1876 by President Ulyssess S. Grant.
Other fees will be in effect at the parks.
The state parks showcase Colorado's diverse landscapes, including John Martin Reservoir State Park on the Eastern Plains and the rock formations at Roxborough State Park in Jefferson County.
The Parks Department is celebrating its 50th anniversary this year. The areas it manages, including more than 4,000 camp sites, draw more than 11 million visitors annually.
