This mountain town is a base for Rocky Mountain National Park (RMNP) and home to lots of wildlife including elk and bears. You DO need a timed-entry pass to get into RMNP this time of year, but you can still get gorgeous views and fun hikes around Estes. Located about 1 hour and 15 minutes northwest Denver.
The famous concert venue! Red Rocks allows visitors to access the park one hour before sunrise until one hour after sunset on non-event days, and one hour before sunrise until 2pm on event days. Located about 20 minutes west of Denver.
