With over 15,000 lakes in Wisconsin, you can bet that no matter where in Wisconsin you live, you're probably not far from one. When the weather begins to warm up and you're looking for outdoor activities, these are some of the best lakes in Wisconsin to cool down on a hot summer day. They are great for fishing, boating, swimming, or just finding a shady spot along the shoreline to admire the view.

1. Lake Mendota - Dane County

One of the most scenic Wisconsin lakes, Lake Mendota is 9,781 acres and might just be the best place to catch a sunset in the state. Once you see it up close, get a bird's eye view from the observation tower at the Capitol Building in Madison.

2. Lake Pepin - Pepin County

This naturally occurring lake is located about 60 miles down from Minnesota - in fact, part of the lake borders Minnesota. One of the most beautiful lakes in Wisconsin, it's also the widest part of the Mississippi River.

3. Devil's Lake - Sauk County

Devil's Lake was once a gorge, but that changed after the last ice age. Now, this 360-acre lake is one of the most popular lakes in Wisconsin. It is surrounded by 500-foot bluffs, which offer awesome views.

4. Lake Winnebago - Winnebago, Calumet, and Fond du Lac Counties

Lake Winnebago is the largest lake in Wisconsin. It is a whopping 137,700-acre lake. It has an average depth of 15.5 feet, and there are many shallow reefs on the shoreline.

5. Green Lake - Green Lake County

This lake isn't the largest, but it is the deepest in the state. It plunges 237 feet. Green Lake is one of the top places for fishing, and there are several charming cabins nearby if you'd like to make a relaxing weekend of it!

6. Wazee Lake - Jackson County

This lake is 1300 acres. But people love it because it is the clearest in Wisconsin. Because of this, it is the most popular lake for scuba diving.

Wazee Lake is one of the best lakes in Wisconsin for swimming and diving since it is so deep. Take a look at this video from Dave's Awesome Adventures to see why it's one of our favorites:

7. Lake Onalaska - La Crosse County

This lake is twelve square miles, with a maximum depth of 40 feet. If you are fishing for panfish, this is your lake. As the sun sets on a day of fishing head to the Red Pines Bar & Grill right on the lake for a fish fry.

8. Lake Koshkonong - Jefferson County

This lake is 10,595 acres. It has a depth of only 7 feet, but don't let that deter you: this beautiful lake in Wisconsin is ideal for a day of splashing around with loved ones. But it's gorgeous and it's awesome if you are fishing for panfish or large mouth bass.

9. Lake Waubesa - Dane County

This lake is 2074 acres in size. It is 38 feet deep at its deepest point. It's a fairly clear lake, although there are lots of algae particles. One of the biggest draws is the boardwalks that surround Lake Waubesa.

10. Shawano Lake - Shawano County

This lake in Shawano, WI has an average depth of 9 feet and a maximum depth of around 42 feet. It is visited mostly for fishing, swimming, and boating. With 18 miles of shoreline, it's one of the best lakes in Wisconsin for beach bums to sit back and enjoy the view.

11. Rock Lake - Jefferson County

This lake has a cool shape, resembling a figure 8. The southern portion of the lake has a part of the Glacial Drumlin State Trail through it, which goes over an old railroad bridge. It also has underwater pyramids built by Aztalan natives.

12. Crystal Lake - Vilas County

This might be one of the prettiest lakes in Wisconsin. It gets its name from the very clear waters, and on a beautiful day when the water is calm and there's no wind, the lake seems to turn into a picture-perfect reflection of the lush surroundings.

13. Lake Michigan - eastern Wisconsin

We would be remiss if we didn't include Lake Michigan on this list. One of our favorite spots along this lake is North Beach. North Beach is located in Racine and has 2500 feet of open shoreline to explore.

Lake Michigan has incredible beaches and there are several places that you should add to your bucket list of best Wisconsin lakes. Check out a flyover of North Beach in Racine in this video from Nate Bruce:
