Grafton Parks, Kilns and the Interurban Trail

A Lake Michigan gorge, riverfront lime kilns, quiet nature trails, a dog park, and the paved Interurban Trail through town.

Published June 15, 2026

For a small town, Grafton parks pack in a lot: a Lake Michigan gorge with a beach at the bottom of a wooded staircase, a riverfront park built around 19th-century lime kilns, quieter nature trails along the Milwaukee River, a dedicated dog park, and the paved Interurban Trail running right through the middle of it all. Here is what each one offers, how hard the walking is, and how to string them into a morning or a full day outdoors.

Lion's Den Gorge Nature Preserve

Lion's Den Gorge is the star, and for good reason. It is a 73-acre Ozaukee County natural area on the shore of Lake Michigan, a few minutes east of downtown, with a main loop of a little over two miles that runs through cedar forest to a wooden staircase down the bluff to a stony beach. It is free, open sunrise to sunset in every season, and doable with kids, with a paved lot, restrooms and picnic areas at the trailhead. A salmon-spawning stream and wetland boardwalks add to the walk, and fall colour and spring wildflowers are the standout times to visit. It rewards more than a quick stop, and the full bluff trails, the staircase and the beach at Lion's Den Gorge are worth reading before you go.

Lime Kiln Park

Closer to downtown, Lime Kiln Park follows the Milwaukee River past the stone remains of the old lime kilns that gave it its name. The kilns date to the 19th century, when limestone quarried nearby was burned here to make the lime used in mortar and plaster, and the surviving stone structures give the park a character an ordinary green space does not have. It is an easy, scenic stroll, open 6am to 10pm, with a playground, a frisbee golf course, ball fields, pavilions and picnic spots along the riverbank, and it hosts community events through the warmer months. It pairs naturally with Lion's Den: the gorge for the lake and the workout, Lime Kiln for a gentler riverside walk and a picnic afterward.

Pleasant Valley Nature Park

For quieter walking away from the lake crowds, Pleasant Valley Nature Park offers natural-surface trails through woods and open space along the Milwaukee River. It is the low-key option when you want a walk without a destination or a crowd, and it comes into its own in winter, when the trails are groomed for snowshoeing and fat-tire biking, a genuinely different way to use a park most towns would simply close for the season. Because it draws far fewer visitors than the gorge, it is a reliable spot for a peaceful hour even on a busy summer weekend. The trails are not always clearly marked, so it rewards a bit of wandering.

Muttland Meadows

Dog owners have their own spot in Muttland Meadows, a dedicated off-leash dog park with 24-hour access, where your dog can run in open fields and wooded areas while you stretch your legs. It has sturdy, spacious entry stalls and is kept clean with bins and scoopers throughout, the kind of well-run amenity that reflects a committed group of local dog owners behind it. It is easy to fold into a day that also includes a leashed walk somewhere quieter, so the dog gets both a run and a stroll.

The Interurban Trail

Tying much of the town together is the Ozaukee Interurban Trail, a paved rail-trail that follows the route of the old electric interurban line that once carried passengers through the county, and now runs right through Grafton. It is flat and smooth, good for biking, walking, running or a stroller, and it connects Grafton with neighbouring towns up and down the county, including Cedarburg just to the northwest and Port Washington on the lake. You can pick it up in town and ride as far as you like, which makes it the easiest way to see Grafton under your own power, a low-effort outing on its own and a genuine transport link between towns for anyone on a bike. It also strings several of the parks together, so you can ride from one to the next rather than driving between them.

Village parks and playgrounds

Beyond the marquee names, the Village of Grafton runs around twenty parks and open spaces across town, so there is usually a playground or a picnic table within a few minutes of wherever you are staying. Centennial Park is the standout for families, with a large all-inclusive playground built for children of all abilities, open shelters for rent, ball diamonds and a half-mile path. River Bend Park adds a free summer splash pad for the little ones. For a full family plan around these, the guide to the pool, the splash pad and the best playgrounds pulls the pool, the splash pad and the playgrounds together.

Making a day of it

A good outdoor day in Grafton starts early at Lion's Den for the loop and the beach before the crowds, then eases into a riverside picnic at Lime Kiln, with the Interurban Trail available any time you want a flat ride or walk. Add Muttland Meadows if the dog is along, and Pleasant Valley if you want one more quiet trail. It all slots easily into the wider run of everything else there is to see and do in town.
