JEFFERSON COUNTY, CO — Jeffco parks and trails remain open amid Colorado's stay-at-home order; however, there are concerns about crowding on trails and in parking lots.

In a letter to Jefferson County residents, officials acknowledged the need to get outside and exercise on trails, but issued a warning for those who aren't adhering to social distancing and COVID-19 parks guidelines.

"As more community members get outside, we're seeing some concerning activities and potentially dangerous behaviors," the joint letter says. "We have every hope of keeping Jeffco parks and trails open for your enjoyment. To do this, we need your help."
