If you are googling up sledding spots and hoping for more than an inch of snow today.
Kipling and Coal Mine, just west. There is a hill that used to not have as many houses, at the far bottom was a fence in front of a drainage creek. I remember growing up that was universally known (my own little world) as the sledding hill. That and Jackass Hill just east past the bridge on Mineral east of santa fe. That place was great before they built on it.

This may come as a surprise to sledding enthusiasts in the Mile High City: It’s technically against the rules to sled in city parks unless it has been specifically sanctioned by city officials. But, Denver Department of Parks and Recreation spokeswoman Angela Casias concedes, “People do sled in the parks.”
After a fresh snowfall, it’s common to find such outlaw fun-lovers at Congress Park, near East Eighth Avenue and York Street; Barnum Park, which offers a fantastic view of the downtown Denver skyline, is located just west of Federal Boulevard and north of West Sixth Avenue; Jefferson Park, a low-key hill surrounded by trees near West 23rd Avenue and Eliot Street; and Ruby Hill Park, 1505 W. Jewell Ave. While park officials generally turn a blind eye to sledding, Ruby Hill and its free winter ski and snowboard facility, the Rail Yard, is one place where sledders could be ticketed because of the safety hazards.
Not quite canal water skiing but good enough.
