Rivers, tubing, swimming, and hot springs in Colorado
Colorado hot springs and water-quality checks
How to check access, reservations, heat, untreated water, harmful algae, posted advisories, and pet safety before soaking or swimming.
Developed and wild hot springs are different trips
Developed facility
Check reservations, hours, age rules, water treatment, accessibility, and facility policies before going.
Wild spring
Confirm public access, trail conditions, land-manager rules, camping permits, and whether soaking is currently allowed.
Heat
Take breaks, drink water, and leave the pool when you feel dizzy or unwell.
Untreated warm water
CDC advises lowering Naegleria risk by keeping untreated warm freshwater out of the nose.
Lakes and ponds
An open-looking beach can still have an advisory
Harmful algae and bacteria are not settled by how clear the water looks. Not every waterbody is monitored, so read posted notices and ask the manager for the current status before people or pets enter.
Keep the health check simple
- Stay out when an advisory or closure is posted.
- When water looks like paint, scum, foam, or a bloom, keep people and pets out.
- Do not drink untreated river, lake, or spring water.
- Contact a medical professional or veterinarian after concerning symptoms or exposure.
