Looking for a nature outing that’s actually fun for the whole family? Just a short 30-minute drive from Milwaukee, Retzer Nature Center in Waukesha is home to the Discovery Trail—a newly renovated, kid-friendly hiking and play area that makes outdoor time both fun and educational.
It’s one of our favorite easy hikes for kids near Milwaukee, and best of all—it’s free to park and explore.
What is the Discovery Trail?
The Discovery Trail is a revitalized version of Retzer’s original Adventure Trail, now expanded with accessibility in mind. The trail was redesigned with help from the Waukesha Rotary Club Foundation, Friends of Retzer Nature Center, and Community Development Block Grants, and it’s packed with features for all ages and abilities.
What You’ll Find on the Discovery Trail:
- Smooth, accessible paths (stroller and wheelchair-friendly)
- A series of “Exploration Stations” with hands-on nature learning and STEM-focused fun
- Sensory-based play areas designed for open-ended exploration
- A giant eagle’s nest perfect for climbing and imaginative play
- Insect, wood, and animal track exploration stations
- A boulder scramble and free play habitat area
- Quiet corners to observe native plants and pollinators
💡 Tip: There are picnic tables along the way, so it’s easy to stop for a snack or rest.
Hike the Green Loop and Boardwalk Trail
After exploring the Discovery Trail, head past it to the Green Loop and Boardwalk Trail. It’s a peaceful hike through a wooded forest, complete with a babbling brook, frogs, turtles, and shaded views.
- The boardwalk is in excellent condition and fully accessible for strollers and wheelchairs.
