Kelso Conservation Area: Trail Guide, Escarpment Lookouts, and Reservoir Access

Located along the brow of the Niagara Escarpment in Milton, Kelso Conservation Area is one of the most versatile outdoor parks in the Greater Toronto Area. Operating as Glen Eden ski hill during winter, the park transforms across spring, summer, and fall into a bustling recreation hub featuring limestone cliff-edge hikes, mountain biking networks, and a 16-hectare reservoir.
