McCarthy Beach State Park spans two lakes near Tower, Minnesota, offering camping sites situated on a narrow peninsula between Sturgeon and Side lakes. The shallow sandy beach at Sturgeon Lake extends approximately 50 feet from shore before deepening, making it popular for families with young swimmers. Most campsites at the park are nestled within stands of mature pine trees.
What to do
Trail exploration: The McCarthy Beach State Park lakeside trail offers scenic walking opportunities among mature pines. As camper Lindsay N. noted, "The lakeside trail was very pretty!" The trail system connects directly to campsites, allowing immediate access to nature.
Water activities: Paddlers can launch directly from the campground at McCarthy Beach State Park. One camper shared, "We had easy water access for our kayak off the campground loop. And it was easy enough to carry the kayak across to the other lake to explore out there." The dual-lake access creates flexibility for wind conditions.
Stargazing: The northern Minnesota night sky delivers exceptional viewing opportunities. Christina W. reported McCarthy Beach State Park is "the best place that I have seen the northern lights." The remote location minimizes light pollution, especially during clear autumn nights.
What campers like
Secluded atmosphere: Button Box Lake Campground provides a technology-free experience in a remote setting. According to Jim F., "First off, and most appealing to me is the fact that there is no cell service. All 12 campsites are first come first serve and you can't jump a line by going on a website to reserve a spot."
Wildlife viewing: The forests around McCarthy Beach State Park support diverse wildlife including loons. Christine T. observed, "Nothing says Minnesota like the call of the Loon and that's what greeted me upon arrival at my site!" Early mornings and evenings provide prime wildlife viewing times.
Beach quality: The swimming area at McCarthy Beach State Park consistently receives high marks. "The sand was so nice and the area was very well kept up! So many tables and spots to sit," wrote camper Megan G. The sand bar extends considerably into the lake, creating expansive shallow water areas.
What you should know
Water conditions: Potential water quality issues can affect campground operations. As Janet R. mentioned about McCarthy Beach State Park, "There is currently a water issue--testing has found contamination in the campground wells, so there isn't potable water and you have to get drinking water from other locations in the area." Check current conditions before arrival.
Site privacy levels: McCarthy Beach State Park campground has variable site spacing. "Electric loop was tight and some sites had minimal privacy. The non electric sites were much more private," explained Camp S. Sites at the loop ends typically offer more separation from neighbors.
Seasonal operations: Button Box Lake Campground operates only from May through September. The campground features rustic amenities with no water or electric hookups, though hand pumps provide drinking water access.
Tips for camping with families
Beach suitability: The shallow water depth at McCarthy Beach State Park makes it particularly child-friendly. Janet R. explains, "The beach is amazing with crystal clear water, shallow depths for kids and family swimming, great picnic spots all along the expansive shoreline." The gradual depth progression allows parents to supervise children more easily.
Group site advantages: Families traveling together should consider the group site at McCarthy Beach State Park. "The Group campsite, which is located in between the beach and the boat access on Sturgeon Lake, is probably the best camping option in the park, with its own indoor shelter and tent sites for groups up to 40," notes Janet R.
Nature programming: McCarthy Beach State Park offers scheduled outdoor activities. Janet R. observed, "There are also naturalist programs, and regular outdoor performances by local music ensembles too, so overall there is lots to do in a relaxing and fun outdoorsy location." Programs typically run weekend afternoons during peak season.
Tips from RVers
Site characteristics: Button Box Lake Campground accommodates smaller RVs but requires careful navigation. Jim F. advises, "All the sites are back in no pull through sites, generally level however there's a few that are on an angle." The campground's remote location requires self-sufficiency with no hookups available.
Distance to services: RVers staying at Button Box Lake should prepare for limited access to supplies. The campground is "located north of Grand Rapids Minnesota about 60 miles or 35 miles from Nashwauk Minnesota which is the closest gas station, grocery store or post office," according to Jim F. Bring all necessary supplies and plan fuel consumption accordingly.
Seasonal facilities: McCarthy Beach State Park has updated restroom buildings that remain operational during the camping season. According to Camp S., "We really appreciated the new restroom facilities." Winter camping is permitted but with reduced services and facilities.
