Trail Biking in Door County


Door County is home to dozens of miles of bike-friendly trails that will take you within view of bluffs, cliffsides, forests, shorelines, waterways, and other fantastic scenery.

But the biking trails are more than just sight-seeing tours. They’re high-speed chases that take riders over rocky and branch-ridden terrain, present them with unique geological obstacles, and offer just enough elevation to keep things interesting.

With cycling season upon us, now is the perfect time to get some inspiration for your next trail-biking excursion, whether you’re dreaming up a day trip or planning to spend a whole week exploring by bike.

Trail Biking Guidelines

Staying on trail is your number one concern when biking in the wilderness. Riding off the trail, especially to avoid wet or muddy areas, can cause erosion and damage vegetation. 

In addition, be sure to:

  • Always wear a helmet, proper footwear, and other safety gear.
  • Keep your group, yourself, and others safe by always riding in control and within your group’s limits.
  • Respect other trail users and protect the quality of their experience.
  • Yield to hikers and equestrians and to uphill-traveling cyclists when you are descending.
  • Be prepared to stop and dismount if the trail is narrow or crowded.
  • Review all of the Door County Leave No Trace 7 Principles.

The Ahnapee Trail

Newport State Park

This northeastern park has seven biking trails that can take you along the Lake Michigan shoreline, aside the peaceful inland Europe Lake, past quiet bays and coves, through dense forest, and in view of islands. Newport’s trails are some of the rockiest, uneven, and challenging in the region, so be prepared for a workout.

Try the 7-mile Europe Bay/Hotz Trail for a longer ride or the Rowley’s Bay Loop Trail for something a little calmer.
