Hidden Valley Campground is one of eight campgrounds within Presqu'ile Provincial Park near Brighton, Ontario. It offers approximately 30–31 non-electrical sites, each with a picnic table and fire pit standard to Ontario Provincial Parks.

A comfort station with flush toilets and showers is located on the west side of the campground. Situated among the furthest campgrounds from the Lake Ontario waterfront, Hidden Valley is considered one of the quieter areas of the park.

The campground operates seasonally, opening around the May long weekend and closing after Labour Day.
