Beach test positive for ecoli 2x this year.

If you stay here do not swim.  They have 2 beaches, they test one for ecoli and close it but leave the other one open because they don't have to test both. It's 50 feet away.  If you don't test, it can't be bad.  How stupid.  They rake goose dumplings into the sand.  Who is managing this place? Camping is fine.  Stay off the beach it's not safe.

Quick escape from the city

This is a nice campground.  A little better than the average Wisconsin state campground.

Pros:

- Clean

- Flush toilets (did not use showers)

- Very nice, sandy and swimmable beach (not true for some campgrounds that I've visited!)

Perk:

- If you call and place and order, a local baker will deliver fresh, homemade cinnamon rolls to your campsite.  You can pay via mobile payment services.  Just look for the signs on the road as you drive in.  The only problem is now camping without waking up to fresh cinnamon rolls will be such a let down! :)

Cons:

- The campsites in the 900s didn't have a lot privacy.  

- Walking from the 900s to the beach was a bit of a trek.

Visited for the day but plan to return to camp

We were staying at Mauthe but it was packed so we came here instead and we're glad we did. The trails, fishing pier and beach are nice. We got caught in a thunderstorm that we waited out in a little tavern in nearby Dundee, which is pretty much the cutest little town around. We plan to return next year to camp.

Nice private sites

Very nice campground. Sites are decent sized for tenting or small camper. Almost all the sites are surround by trees and small brush so it gives a private feel. Took a ride over to the town of Dundee and checked out Hamburger Haus for some HUGE ice cream cones. Decent biking trail system to beach and bike trail that connects to Maithe Lake. Would give five stars if the showers and bathroom were a little nicer as they are pretty dated looking.

Great Family Campground

This campground is great for family and offers many wooded sites. The lake is rather shallow so best for swimming in early summer or warm fall days. Nicely situated in Kettle

Good campsite if you don’t have dogs

We stayed 700, enough space, good hiking trail, nice beach. But the pet picnic area was pretty disappointing. Just a small opening for a dog jumping in the water. All the nice beach area was not open for a dog. My pup was pretty sad.

Site 907

Our site was a bit less secluded than I’d prefer but still very nice. The loop we were on the lower 900 loop, had quite a few sites that could be combined to be group sites. Two sites completely adjoining or with very little separating them. This loop would be good for an option if the group sites are unavailable. Especially the inner loop sites that back up to each other. We walked some of the other loops and the did not all seem this way, stuff especially in the 700’s loop being a bit more wooded with some nice sites being my favorites, and also some nice sites in the upper 900’s loop that were spaced out nicely. Great hiking nearby, flush toilets, showers, nice little beach, plenty of downed wood around and also available to purchase 5$ a stack, pet friendly except no dogs allowed on the beach. There is a dog friendly picnic area near the water though. Nice get away pretty close to Milwaukee, Chicago, etc...

Huge campgrounds with access to the lake

At the last minute we decided to go camping for the holiday weekend. We called 6 campgrounds close to us on Thursday at noon and this was the only one with availability. Best part about the campgrounds is that the showers have great pressure despite the buildings being old, the camping spaces are typically spacious, and there is lots of felled wood that you can use in your fire pits. The negatives as a dog owner is that dogs are not allowed on most trails or on to the beach.

Close to most folks for a get away. Clean and quiet. Nice fishing and swimming. Great trails. You can reserve or try your luck on getting in especially during summer season.

Frequently Asked Questions

Where is Long Lake Campground located in Wisconsin?

Long Lake Campground is located in the Northern Unit of the Kettle Moraine State Forest in Wisconsin. It's situated near the small town of Dundee and close to Campbellsport. The location is relatively accessible, being only about 2.5 hours from Chicago, making it a convenient getaway destination for both Wisconsin residents and visitors from neighboring states. The campground is positioned alongside Long Lake, surrounded by the beautiful rolling terrain characteristic of the Kettle Moraine region.

How does Long Lake Campground compare to other Kettle Moraine camping options?

Long Lake Campground is generally considered slightly better than the average Wisconsin state campground, offering more amenities and recreational options than some alternatives in the area. Compared to Mauthe Lake Campground (another popular Kettle Moraine option), Long Lake tends to be less crowded while still providing excellent facilities. Long Lake stands out for its quality beach area and swimming opportunities, which aren't consistently available at all Kettle Moraine campgrounds. The wooded sites offer good privacy, and its extensive trail system is particularly noteworthy. When Mauthe Lake gets full, Long Lake serves as an excellent alternative with comparable natural beauty but often a quieter atmosphere.

What recreational activities are available at Long Lake Recreation Area?

Long Lake Recreation Area offers numerous recreational opportunities for visitors. The lake features a clean, sandy beach perfect for swimming, especially in early summer or warm fall days. Fishing is available from piers on the lake. An extensive trail system surrounds the area, including a 7-mile-long biking trail (one way) and multiple hiking paths through the kettle moraine terrain. The area also connects to the broader trail network of the state forest. For those willing to venture slightly off-site, the nearby town of Dundee offers additional attractions, including the Hamburger Haus known for huge ice cream cones.

What amenities and facilities are available at Long Lake Campground?

Long Lake Campground offers clean facilities with flush toilets and shower buildings that provide excellent water pressure. The campground has several loops with numbered sites (including 700s and 900s loops), with many sites nestled among trees and brush for privacy. Most sites can accommodate tents or small campers. Facilities include a sandy beach area for swimming, fishing piers, picnic areas, and a designated pet area (though it's limited in size). The campground is well-maintained with a mix of more open and wooded sites, some of which can be combined for group camping.
