Winter Trail Advisory

In the event of snow, note that we only plow the parking lot at our headquarters at Four Mills Nature Reserve--as soon as staff are able to safely get there. All other parking lots are not plowed and trails are not shoveled. Use your best judgement when visiting and stay safe.

Bike Trails

Although the majority of our trails are not built for and do not allow bike riding, there are several suitable biking trails close by: 

 

Ft. Washington State Park, part of the Montgomery County Parks system, maintains a 2-mile stretch of the GRT that is paved and allows biking

 

The Crossways Trail connection in Blue Bell is paved and allows biking  

 

Wissahickon Trails'  Dodsworth Run has paved trails accessible to bikes

 

The Forbidden Drive Trail is a 7-mile, bike accessible, trail along the Wissahickon; it also connects with other trails built specifically for mountain biking  

 

The 202 Parkway Trail connects three towns – Montgomery, Warrington, and Doylestown – on its 8.4 mile route paralleling the scenic byway

 

And if you want to really get out of town by bike, check out the Circuit Trails, a 5 county, two state trail network in Greater Philadelphia.
