O'Reilly Lake Resort

O'Reilly Lake Resort in Mountain Grove, Ontario, offers 9 RV sites, eight cabin and cottage units, and 17 tent sites on a spring-fed lake, with 30-amp water-and-electric service and rigs accepted to 50 feet. A single 30-amp water-and-electric category joins a water park, beach, boat rentals, jumping pillow, and recreation center. Nine back-in sites carry water and electric on 30-amp, sized to 50 feet, with picnic tables. Two things to plan around: the sites carry water and electric rather than sewer, and service is 30-amp, so bring an adapter if your rig runs heavier. One consistent category means no guesswork. Eight cabins and cottages and 17 tent sites make this substantially a cabin and tent property. A general store, laundry, restrooms, showers, propane exchange, and firewood handle the practical side. A water park and beach anchor the summer, with boat rentals opening the lake for boating, paddle boats, paddle boarding, canoeing, kayaking, swimming, and fishing. A jumping pillow, recreation center, sports courts, volleyball, horseshoes, walking trails, hiking, biking, mountain biking, and a playground fill the rest, with live music, picnicking, and genuinely dark skies for stargazing. The address is 1091 O'Reilly Lake Lane in the Township of Central Frontenac, where the Canadian Shield's ancient granite and the spring-fed lakes of the Frontenac Axis make classic Ontario cottage country. Frontenac Provincial Park and Bon Echo are within reach, with Kingston about an hour south. Summer is the short, intense Ontario season. Reserve well ahead for July and August.
