A fantastic way to beat the heat during Colorado’s sunny summers is by heading out on a float trip! Whether you’re looking for a leisurely ride or a slightly more adventurous experience, there are plenty of rivers to float in Colorado that cater to every comfort and skill level. Float trips are typically best on rivers rated Class II. These offer moving water with clear, wide channels and easily avoidable obstacles, making them ideal for most floaters.

How to Choose the Best River for Your Colorado Float Trip

When selecting a river for your float trips, consider the water level, type of vessel, accessibility, and your comfort or experience level. Mellow rivers like the Colorado are great for beginners and families, while faster creeks like Boulder or Clear Creek can be better suited for those with some experience. For deeper or faster-moving water, opt for a raft or inflatable kayak (duckey), while smaller, calmer flows are perfect for inner tubes. Accessibility, safety, and rental availability are also important—some rivers have clear access points and outfitters nearby to help you gear up and go.

1. Colorado River

Why it’s float-friendly: With its calm Class II rating and scenic surroundings, the upper Colorado River is a go-to for an entire day of floating fun.
Best time to go: Late spring to early fall, when flows are steady and weather is warm.
Recommended vessel: Raft for comfort, duckey or SUP for a challenge.

The upper section of the Colorado River is ideal for full-day floats with long stretches of tranquil water. Rafts are great for relaxing, but if you’re seeking a bit more excitement, you can hop on a duckey or stand-up paddleboard (SUP) for a more engaging experience. These smaller vessels raise the difficulty slightly, edging the experience toward Class III.

2. Boulder Creek

Why it’s float-friendly: Accessible and well-loved by locals, Boulder Creek offers a short and splashy tubing adventure.
Best time to go: Early to mid-summer, when flows are between 100–200 CFS.
Recommended vessel: Inner tube, duckey, or kayak.

Floating Boulder Creek is a favorite summertime activity among Boulder locals. The sweet spot for tubing is when the water flow is between 100 and 200 CFS. When it exceeds 200 CFS, things get significantly more dangerous, and when it hits 700 CFS or more, the creek is officially closed to floaters for safety.

You can tube, kayak, or duckey down the creek. Tube rentals are easy to find, but a budget-friendly option is picking up a durable auto tire inner tube from a recreation store. These handle rocks and debris much better than inflatable tubes.

3. Clear Creek (Golden)

Why it’s float-friendly: Offers both mellow and thrilling sections, depending on where you enter and exit.
Best time to go: Mid-summer when water is manageable but still flowing.
Recommended vessel: Inner tube, duckey, or kayak.

Tubing Clear Creek through Golden can be an amazing time, but it’s important to choose the right section. Certain areas of Clear Creek are rated Class III–V, which are not safe for tubing. For a true float, put in at White Water Park and take out at Vanover Park.

The right stretch offers a fun mix of splashy water and beautiful views. Rentals and gear are widely available in Golden, so you’ll have everything you need for a safe and enjoyable float—whether you’re tubing, kayaking, or paddling a duckey.
