Garfield Creek State Wildlife Area protects elk and closes in winter
Garfield Creek State Wildlife Area south of New Castle is elk winter range, so it closes to the public for much of the year and requires a license or wildlife-area pass to enter.

Garfield Creek State Wildlife Area, in the hills south of New Castle, is not a park. It is land Colorado holds mainly for wildlife, and elk are the headline species. The area runs from low winter range up to high summer country, so a herd can spend much of its year here.
Because winter range is where elk survive the hard months, this State Wildlife Area closes to people for a long stretch of the year, roughly from early winter into mid-summer, with a narrow exception for spring turkey hunters. The reason is simple: animals that are pushed off their winter ground when food is scarce and the cold is deep can die from the stress. Staying out is how the place does its job.
State Wildlife Areas also have an access rule many visitors miss. Anyone 16 or older needs a valid Colorado hunting or fishing license, or a separate State Wildlife Area pass, just to set foot on the property. A regular state-parks pass does not cover it.
From the area you can also reach neighboring national forest and BLM land, but the SWA’s own seasons and rules apply while you are on it.
