I hiked the loop in a clockwise direction from its trailhead at the Trout Brook Farm Campground, familiar to me from my hike of Trout Brook Mountain two days prior. The ponds, in that east to west sequence, are Littlefield Pond, Billfish Pond, Round Pond, High Pond, and Long Pond, accessed through a series of side trails. Billfish and Long each have canoe rentals (through the ranger at Trout Brook Farm campsite).
At the beginning of the trail up Trout Brook Mountain, the emerald colors of hobblebush contrast with the darker forest, particular as it transitions to evergreen. The trail winds through this forest and climbs rocky ledges dressed in soft green moss, with excellent northward views toward Trout Brook, Grand Lake Matagamon and the north woods.
