Did you know there are beaches in Denver?!? We took a quick trip over to Aurora Reservoir in Aurora, CO. While there isn't quite as much offered in this park as there is at Cherry Creek Reservoir, there is still an awesome 7.8 mile hike and bike trail around the water and plenty of wildlife to see. The Aurora Reservoir has fishing, archery, standup paddle board and kayak rentals, swimming, scuba, and boating.
