Just south of Estes Park, CO and ~30 minutes to rocky mountain national park.  This county park is a hidden gem.  Huge open space preserve with a few great hikes (Kruger rock had phenomenal views but moderately strenuous).  We stayed in the bobcat loop that was 2.5 miles up a dirt road from the entrance.  Aside from the windy dirt road, no complaints from us - would stay again!
