Grinnell Woods

Washington, Knox County

QUICK TRAIL FACTS

  • Preserve Size: 96 acres
  • Trail Mileage: ~1.7 miles
  • Pets: yes
  • Difficulty: easy to moderate
  • Sights: Little Medomak Brook, mature forest

The Grinnell family, which has created an easement on their land, invite the public to walk along a parcel wedged between a brook and a bog that brings you to a knoll of beautiful old conifers and a lovely spot by a stream that feeds the Medomak River.

The trail begins as an easy, wide track covered with wood chips, bringing you through a forest clear-cut in the last century. It crosses a power line corridor and a little bridge where the brook kisses the bog. You’ll pass a large boulder, I assume it’s an erratic? The most dramatic part of the trail is where it departs the younger forest and heads up a hill through older-growth trees and the light dims. Here the trail narrows and becomes a little less easy.

When you reach the top of the knoll, at about 0.6 miles, you’ll find the roughly 0.5-mile loop trail, Little Medomak Loop, that brings you to the brook. It was flagged with tape in the fall of 2025 and easy to follow.

Directions: The trail is marked with a prominent sign for Grinnell Woods off Route 17 (Augusta Road), about 1.1 miles west of the intersection with Route 220 (Waldoboro Road). There is a large parking lot and trailhead kiosk. The address is 241 Rockland Road.

  1. The lollipop loop at “top” of the trail was not completed at the time of your hike. Work on that section is planned for the end of June 2025. It is a very nice trail and the loop at the top through the old forest will be gorgeous!

  2. The loop by the river is now complete and being used. Also the trail head is 1.1 miles EAST of rt 220 (Waldoboro RD) intersection on Rt 17. Glad you enjoyed the hike and hope you come back….J Grinnell
