Best Boating Lakes in Colorado

Explore some of the best lakes in CO for boating below. Whether you want to jet ski or chase trout in hidden coves, Colorado has the perfect spot for your next trip. 

Grand Lake

We're kicking things off with Grand Lake, Colorado's largest natural lake, which offers views of the famous Rocky Mountains. It's the ultimate spot for outdoor lovers, especially powerboating, kayaking, and sailing.

You could easily spend a few weeks exploring Grand Lake and enjoying hikes, water sports, and its famed fishing. It's connected to the Shadow Mountain Reservoir and Lake Granby, allowing for even more exploring and a slightly more tranquil escape. 

Blue Mesa Reservoir

Blue Mesa Reservoir is a top-tier fishing location, especially for trout and kokanee salmon. It's the state's largest lake, with vast open waters ideal for boating and water skiing in late summer. 

Lake Granby

The lake trout and rainbow trout are plentiful. When they're on, you can enjoy some exciting fishing. 

Chatfield Reservoir

If you're looking for a day trip from Denver, Chatfield Reservoir sits just southwest of the capital. It's got easy access, great launch spots, and it's perfect for boating, trout fishing, paddle sports, waterfront camping, and getting away from the city's hustle and bustle. 

Cherry Creek Reservoir

Another option close to town is Cherry Creek Reservoir to the southeast. It's a popular spot known for its sandy swimming beach, boat ramps, and water activities, including stand-up paddleboarding, kayaking, and jet-skiing. 

Twin Lakes

Want some of the best views and more than 2,7000 acres of water to explore? Twin Lakes has got you covered.

It's a hot spot for boating, camping, fishing, and kayaking near the San Isabel National Forest. 

Monarch Lake

For a quieter getaway against a stunning alpine backdrop, Monarch Lake is ideal for quiet paddling and photography-focused outings. You can follow the Monarch Lake Loop Trail across the shore before heading in for a paddle or dip. 

Boulder Reservoir

Boulder Reservoir is a 700-acre multipurpose recreation and storage facility popular for a range of water activities, including boating and waterskiing. Remember that to operate any watercraft, including motorized and non-motorized, you'll need a watercraft permit. 

Lake Nighthorse

For a kid-friendly lake just out of Durango, Lake Nighthorse is a fantastic option. The waters are usually relatively calm and crystal clear, and the lake is stocked with fish. The conditions are perfect for boating, paddle sports, or swimming. 

Bear Creek Lake

We're rounding out the list with Bear Creek Lake near Red Rocks. The site itself comprises three lakes across 2,600 acres of park, with 15 miles of trails to explore. Water access is easy, and many opt to spend the day boating or paddleboarding.

What Is the Most Beautiful Lake in Colorado?

Twin Lakes dazzles visitors with tranquil views and the majestic reflections of snowy peaks and trees across still waters. However, Coloradans are spoiled for choice when it comes to beautiful lakes.

Well-preserved and maintained by the Department of Natural Resources (DNR), many of the state's lakes have a stunning backdrop of mountain ranges. Monarch Lake offers views similar to those of the surrounding mountains, making it a postcard-worthy destination year-round. 

Apart from being one of the best boating lakes, Grand Lake deserves an honorable mention for its alpine views, charming, quaint town, and a wooden boardwalk lined with shops and restaurants, where you can enjoy a nice meal after a day on the water. 

Are There Any Warm Lakes in Colorado?

Because most of Colorado's lakes are alpine, the water can stay pretty chilly. Lower-elevation reservoirs will be your best bet for warmer water temperatures, especially during late summer, when the water is more comfortable for swimming and boating.

For warmer reservoirs by Colorado standards, head to Chatfield Reservoir, Cherry Creek Reservoir, Boulder Reservoir, and Lake Nighthorse. 

How to Stay Safe When Boating on Colorado's Lakes

Safety should be your top priority on the water. Whether you've been boating for a while or are a newcomer, a boater education course like those offered by ilearntoboat should always be the first port of call. Regulations can change, and if you're not up to date on the latest safety requirements or state-specific rules, you risk injury, property damage, or worse. 

Before your trip, check weather forecasts, as mountain streams and weather patterns can change rapidly, especially at high altitudes. Pay attention to the wind on the more exposed lakes and reservoirs, as choppy conditions can develop. 

Next, check boating regulations and site-specific rules (such as those related to closure, boating passes, and algae). Pack and wear U.S. Coast Guard–approved life jackets in the correct sizes for all passengers, and prepare for changing conditions with layers, sunscreen, plenty of water, and a first-aid kit. Make sure your navigation lights are in the proper working order, especially when boating around dusk, as the day can get away from you on the water. 

Finally, be prepared for cold-water conditions. Hypothermia risk remains high even during the summer due to snowmelt and changing conditions. Always dress for water temperature, not air temperature, if you're going to be out on the water.
