Even though Colorado is landlocked, it does not lack beaches. In reality, enjoying beach time is one of Colorado’s best things to do.

Colorado has over 4,000 lakes and reservoirs, and that does not include the state’s creeks, streams, and rivers. Colorado, of course, provides plenty of opportunities to cool off in cool and refreshing bodies of water during the hot summer months.

But where in Colorado are the best beaches? Continue reading to find out.

When you think of Colorado, you probably think of breathtaking views of the Rocky Mountains, not beaches.

Consider mountain water that is clean and crisp. There are breathtaking mountain views, pristine coves, and inlets from every angle.

This list will provide plenty of adventure and relaxation, whether it’s sunbathing, camping, water sports, or building sandcastles.

Of course, the best time to visit is in the spring and summer, when temperatures are pleasant but not oppressively hot, and the water is cool and refreshing. Furthermore, many of Colorado’s beaches are located within larger parks, allowing you to spend an entire day exploring everything these protected areas offer.

1. Boulder Reservoir

The Boulder Reservoir is one of the largest and most beautiful beaches. This 700-acre lake was built in the 1950s primarily to provide water to Boulder. While it continues to provide Boulder with potable water, the lake has grown into one of Colorado’s best summer swimming spots.

Although the lake is open all year, most visitors come during the summer season, which runs from mid-April to mid-October. The beach is open until 6 p.m. every day. It’s an excellent place for families because it has a shallow section for the kids and floating platforms in the middle of the lake for sunbathing.

Visitors to the lake can rent pontoon boats, sailboats, stand-up paddleboards from Rocky Mountain Paddleboards, and tanning and swimming. The Boulder Reservoir Loop Trail allows you to access the lake’s fantastic fishing.

Rainbow trout, bass, and other species can be abundant.

You can, of course, walk, run, or bike around the lake.

2. Blue Mesa Reservoir

The Curecanti National Recreation Area, managed by the National Park Service since 1965, contains Colorado’s largest body of water, the Blue Mesa Reservoir.

It is home to the largest kokanee salmon fishery in the United States, making it one of the state’s most popular public fishing spots.

3. Medano Creek

One of the highlights is the Great Sand Dunes, National Park. Bring a bathing suit because, even in this unlikely location, you will be amazed to witness this creation.

Rivers flow down to the dunes, forming beautiful natural beaches, thanks to snowmelt from the Sangre de Cristo mountains.

When the Medano Creek River is experiencing “surge flow,” which is when snowmelt is at its peak, it is the best time to visit the beach (typically in the spring). This results in a churning (but safe) wave pool that is always fun to swim in.

The water is highest between May and June, which is peak season. Remember that the river is heavily reliant on snowmelt, so don’t expect the same experience every time. The river also tends to dry up by the end of the summer, so plan your visit accordingly.

Chatfield State Park is a park just outside of Littleton, Colorado. The reservoir at Chatfield State Park, one of the lovely beaches, is a spot to soak up the sun in Colorado. Enjoy the view of the Rocky Mountain foothills as well.
