Trail Lake Park located on Ravenna Road is now open. The Portage Park District acquired the property on the southern boundary of Herrick Fen State Nature Preserve. The park property provides an important buffer and a future trail connection to the fen and includes a 30-acre lake, mature forest, former agricultural fields, wetlands, and a remnant of the early 1800s railroad corridor.

The first phase of construction at the park includes:

• 50-car parking lot on Ravenna Road
• Information kiosk, benches, tables
• Handicapped-accessible 1.6-mile multipurpose trail around the lake and secondary natural surface trails for hiking, biking, skiing, and nature education
• Vault Restrooms
• Access to the lake for fishing and paddling

There are plans to add a picnic shelter and trail access to Herrick Fen
