Family-friendly swimming holes in Colorado

Choosing a Colorado swimming hole with kids

The two things that actually matter with children are the approach and the entry. Every listing here has an easy approach — short, marked, and walkable while carrying a cooler — and facilities on site, which usually means parking, restrooms, and somewhere to sit.

The entry matters just as much and varies spot to spot. A gradual sand or gravel shelf is very different from a ledge that drops to eight feet a step from shore. Read the individual listing, and walk the entry yourself before the kids get in.

High-elevation water is cold — typically 50s to low 60s°F even in July. Developed hot springs run 95-110°F.

Facilities are not supervision

A restroom and a picnic table do not mean a lifeguard. The large majority of natural swim areas in Colorado are unguarded, including many inside state parks, so an adult needs to be watching the water the whole time — not reading, not on a phone.

Keep young or weak swimmers in a properly fitted life jacket rather than arm bands or inflatable rings, which drift and flip. Designate one adult as the water watcher and rotate the job every fifteen minutes; drownings are quiet and fast.

Check for advisories before you drive. Colorado Department Of Public Health And Environment publishes the water-quality and algal-bloom notices for Colorado. Discolored water, surface scum, or a strong smell means keep everyone — and the dog — out.

Timing and conditions in Colorado

Colorado swims late june through august, best july to mid-august. Hot springs are a year-round draw; natural creeks and lakes are realistically swimmable only in high summer.

Peak runoff from late May into early July turns ordinary-looking creeks into lethal current. Altitude also shortens breath-hold and speeds hypothermia, so cold water bites harder here than the same temperature at sea level.
