From the first hint of Spring through the end of summer, activity on Thompson Lake truly comes alive. This is considered peak season in the lakes region of Maine and outdoor activities abound. Sights commonly seen on Thompson lake include groups of sailboats crisscrossing the lake captained by children learning to sail at one of the two camps on the lake, boats pulling a waterskier or someone out for a joy ride on a tube, canoers and kayakers exploring the shore, vacationers basking in the sun on docks or swim up floats, jetskiers skipping across the water, fisherman trolling the water, loons diving under the water, pontoon boats with groups of people enjoying a tour of the lake, and swimmers diving off of docks.
Skiing is also a popular winter attraction. Shawnee Peak Ski Resort, Mount Abram Ski Resort, and Sunday River Ski Resort are all nearby and all offer fantastic downhill skiing opportunities.
