Trails at / from Kroka

Kroka’s campus is open to the public and we invite the local community to use our trail for non motorized use in all seasons. In 2018 we completed construction of a Trailhead Parking Lot at the West end of campus, establishing public access to Kroka’s trails. Kroka’s 120-acre campus is endowed with several unique natural features including a large beaver pond and marsh network, 30’ granite cliffs, glacial erratics, and pockets of spruce-fir forest. Trails extend beyond the property into the Grassy Brook Wilderness, a large area of private conservation land. The wide open Grassy Brook corridor is home to otters, beaver, moose, coyote, fisher, and bears as well as birds of prey, eagles, barred owl, great blue herons, and other marshland birds. 

Our trail network has been built by Kroka students and is a work in progress, with more trail sections added each year. Presently, the following trails are open for public access:

Beaver Pond Loop – ¾ mile blue-and-white blazed loop trail beginning and ending at Kroka’s Trailhead Parking. The loop crosses Kroka’s campus and connects the Beaver Pond and Porcupine Cliffs. 

Grassy Brook Trail – 1.5 mile white-blazed out-and-back trail from Kroka’s Trailhead Parking to the Grassy Brook Campsite. Completed in 2018.  

Duck Hole Trail – 1 mile white-blazed out-and-back trail extending from the Grassy Brook Campsite to Duck Hole. Completed in 2021. Duck Hole boasts a “whaleback rock” that rises 30 feet from the water and is easily scalable for a view! Trail construction from Duck Hole to Baine Road is ongoing. 

Village Loop Trail –  5 mile blue-blazed loop trail originating from downtown Marlow at the trail kiosk off of Rte 10. The trail was constructed in 2016 and connects many existing trails managed by local snowmobile clubs and the Monadnock Conservancy. 

Trailhead access is from the parking lot along Route 123. Foot traffic only. Please stay on marked trails, and report any maintenance issues to
