Pop Jet Fountain

If you’ve got a toddler who melts down the second summer heat hits, this is your go-to spot. The pop jets shoot up from the ground in unpredictable bursts, which means kids absolutely lose their minds trying to dodge them — or just stand directly in the spray and get soaked. Parents get benches and a clear sightline, so you’re not chasing anyone around blind. It’s right in Boulder, easy to get to, and honestly one of the better ways to burn an afternoon when it’s too hot to do anything else.
