Camping is available within the park, with a mix of serviced and unserviced sites that accommodate tents, trailers, and RVs.

Day-use visitors also make frequent use of the park’s picnic areas and shoreline access, particularly during the warmer months.
Thunder Lake plays a central role in the park experience, supporting swimming, paddling, and fishing activities. Canoes and small boats are commonly used on the lake, and anglers can expect to find species typical of northwestern Ontario waters, including walleye and northern pike. With open views across the water and minimal light pollution after dark, the park is also known as a quiet place to unwind in the evening, especially for travellers breaking up a long drive.

Facilities & Recreation
Aaron Provincial Park is well set up for both day trips and longer camping stays, with facilities that make it easy to relax and enjoy time outdoors. The main campground includes a modern comfort station with flush toilets, hot showers, laundry facilities, and accessible features designed to support visitors with mobility needs. Drinking water taps are spread throughout the park, and additional vault toilets are available in other areas for convenience.
Water activities are a big draw at the park, thanks to Thunder Lake. Visitors can launch boats near the fish cleaning hut or explore the lake by canoe or kayak. Rentals are available at the park office, making it easy to get out on the water without bringing your own equipment. On windy days, conditions on the open lake can change quickly, so keeping an eye on the weather is a good idea.
Swimming is available at two sandy beaches located on opposite sides of Thunder Lake. Both beaches offer shallow entry points and nearby amenities such as picnic tables, parking, and washroom access. Families will also find a playground and open grassy areas nearby, giving kids plenty of space to burn off energy between swims.
For those who prefer to stay on land, the park offers a couple of short hiking trails that highlight different aspects of the landscape. The Aspen Trail provides a walk through boreal forest, while the Eastern White Cedar Trail offers a glimpse into the park’s natural history. Fishing is another popular activity, with several species found in the surrounding waters. A well-equipped fish cleaning station with running water and lighting is located close to the boat launch.
Campers have access to practical services that make longer stays more comfortable, including an RV and trailer dumping station, firewood available for purchase, and a small park store located in the park office. The store carries basic supplies, ice, and souvenirs. Pets are welcome throughout the park as long as they are kept on a leash, so visitors can bring their dogs along to enjoy the trails and campground.
