You've spent all your money preparing for Valentine's Day? Not to worry, there are plenty of sweet deals out there. You can stretch both your body and your mind this weekend in Denver, without paying a cent! Here are five options:

Ruby Hill Rail Yard
Open 5 a.m. to 11 p.m. Daily
Ruby Hill, South Platte River Drive and West Florida Avenue
For the fourteenth year, the Ruby Hill Rail Yard in Denver's Ruby Hill Park is now open to both snowboarders and skiers. The park is already a favorite for sledders, but this facility sports ten rails and boxes of varying configurations and skill levels, as well as some new features for 2020. Ruby Hill Rail Yard was created in 2007 as a joint venture between Denver Parks and Recreation and Winter Park Resort, which has been tied to the city since it opened eight decades ago. For nighttime fun, Ruby Hill Rail Yard is illuminated from dusk until 9 p.m., and always absolutely free. Find out more on Facebook.
