Bog Brook Trailhead (2.5 miles blue blazes) - is on the Halldale Road next to Bog Brook Marsh. The trail can also be accessed from the Whitten Hill parking lot and using the Whitten Hill Trail. The trail traverses a wide range of woods, glades and wetlands. Animal tracks and beaver activity are common. On a north facing slope are mature hemlocks that generations of woodcutters have spared. 

Eric Bruun Trail (0.4 mile blue blazes) - named for the former landowner and modern-day hermit, the trail begins in a mixed northern hardwood forest with a scattering of large white pines. It continues through an extensive hemlock forest with an open understory. 

Big Pines Trail (0.5 miles red blazes) - named for several large pine trees along the route this flat, easy trail ends near a quiet marsh and a nearby small stand of stately pines. Hikers can follow the Bog Brook Trail back to the Bog Brook trailhead for an easy one mile loop. 

Arnold Trail (0.3 mile yellow blazes) - named for the landowner, artist Anne Arnold, this flat, easy trail winds through an stand of hemlocks stretching nearly its entire length to where it intersects Bog Brook trail. 

Hemlock Hollow Trail (east section 0.8 mile blue blazes) - this trail crosses Halldale Road; on the east side of the road, the trail skirts the edge of a deep ravine, eventually crossing the uppermost section of the Sheepscot in a quiet, mature mixed forest. The stream here is excellent rearing habitat for Brook trout and Atlantic salmon. The eastern section of the trail ends at the junction with the Hogback Connector Trail. 

Hogback Connector Trail (1.5 miles blue blazes) - links SWLA trails with 11 miles of trails on Hogback and Frye Mountains maintained by the Georges River Land Trust. Where the “Hog” Connector leaves Bog Brook Trail it is .8 mile to the junction with Hemlock Hollow Trail. The trail then turns southeast and travels 0.7 mile up Hogback Mountain to the Hogback Loop Trail. 

Hogback Loop Trail (1.8 miles blue blazes) - the Hogback Loop trail winds through a variety of multi-aged forest types. A rocky outcrop on the east side of Hogback that offers fabulous views all the way to Penobscot Bay. This trail and the section of Hogback Connector that ascends Hogback Mountain are closed during deer hunting season except on Sundays.
