Lion's Den Gorge Nature Preserve represents one of the last stretches of undeveloped bluff land along the Lake Michigan shoreline, from Mequon up to Port Washington.

Over 1/2 mile of 90- to 100-foot bluffs look out onto Lake Michigan, offering tremendous viewing opportunities for residents and visitors.Lion's Den Gorge Nature Preserve is also adjacent to a 44-acre wetland complex owned by United States Fish and Wildlife Service (USFWS) for enhancing populations of migratory birds and other wildlife.

This park offers tremendous views. Stroll across bridges over the gorge or down the gorge stairways to walk along the Lake Michigan shoreline. This 73-acre park offers plenty of hiking trails, boardwalks through the wetlands, picnic areas and a new shelter in 2023, scenic views, and restrooms.
