Cheesman Park

Cheesman Park is located in the Capitol Hill neighborhood of
Denver, Colorado. The park is one of the most visited spots in
the city and attracts many outdoor enthusiasts, joggers, and
those who want to spend some peaceful time outside. This park
spans around 80 acres and is filled with trails, fountains, and
close to around 2,000 trees. While most people go there to enjoy
the scenery what they don’t know is that they are walking on the
graves of those who were buried over 150 years ago. When night
falls this park becomes something else and is one of the most
haunted places in the entire city.
