Red Rocks Park and trails open one hour before sunrise and close one hour after sunset on non-show days. Admission is free to visit Red Rocks Park, Amphitheatre, Visitor Center, Trading Post and the Colorado Music Hall of Fame.
Dinosaur Ridge Trail is a paved path which is open to pedestrians, bicyclists, and hiker. The site is world-famous for its Cretaceous period tracks and Jurassic period bones and remarkable geologic features. With more than 15 fossil and geologic sites that can be accessed by foot, bike, or guided bus tour, there is nothing in the world like it. Walking the Ridge Trail takes 1-2 hours and is just over two miles round-trip on an inclined paved road.
The Denver Aquarium, Denver Children's Museum, Ball Arena, Elitch Gardens and Meow Wolf are all near downtown Denver. McGregor Square, The Dairy Block, Coors Field, Union Station, 16th Street Mall are all within walking distance of one another. I would recommend taking a ride share or utilizing the light rail system instead of driving if you go down town.
