Carpio-Sanguinette Park (Former Sewage Treatment Plant)

On the north bank of the South Platte in Globeville sits a park almost nobody visits, built directly on top of a 1937 sewage treatment plant. When the city reclaimed it in 1999 they didn't bulldoze the infrastructure — they kept the concrete settling ponds, aeration raceways, and sand-filter walls and turned them into benches, sculptures, and the boundaries of the ball fields. It quietly won an American Society of Landscape Architects design award for the reuse. You're literally picnicking on top of where Denver's waste used to bubble.

The move: Bring coffee and walk the grounds reading the old plant structures like an industrial scavenger hunt, then link onto the South Platte River Trail / 9 Creeks Loop for a longer riverside stroll.
