Choosing the best lakes in Colorado to visit throughout the year is no easy task.
Despite Colorado being the 6th driest state in the country, the state has some spectacular lakes and reservoirs to visit on a hot summer day.
Whether it’s jet skiing, sailing, or just a good old fashion dip into the water, Colorado is home to more than 4,000 bodies of water, both natural and manmade.
And many of the lakes and reservoirs are within a short drive from Denver or Colorado Springs, and make excellent day trips.
And it’s not just for summertime! Several lakes in Colorado offer ice-fishing and ice-skating during the winter.
Beyond water activities, there are also loads of things to do nearby. Most Colorado lakes offer access to hiking, sunbathing and swimming beaches, picnic tables, and camping!
In this guide, we are sharing the top 10 most beautiful lakes in Colorado for fishing, boating, camping, and swimming.
