The Mountain Trail -
Passing through the Forest Plots, the Mountain Trail enters a beech woodland, which in the spring is covered in bluebells.
The route runs parallel with the Shimna River before crossing it over the Boundary Bridge.
The trail continues along one of the Shimna’s tributaries through mature conifer forest. Good views of Luke’s mountain can be had as the trail reaches the boundary wall before zigzagging back toward the Spinkwee River, crossing at the Hore’s bridge.
For those seeking a longer walk - from the crossroads follow the optional Drinns Trail.
(The Drinns are two distinct hills clearly seen from the main car park. The easterly Drinn is the highest point in the Forest Park at 255m. The Curraghard viewpoint offers a resting spot to view the expansive view of the Northern Mournes, Dundrum Bay, Newcastle and the Irish Sea)
This Black Trail adds a further 2.9 miles by circumnavigating the Drinns running along the boundary wall and past conifer forest to Curraghhard viewpoint and back to the Mountain Trail.
The second half of the Mountain Trail passes through conifer plantations at various stages of maturity before reaching the second crossing point of the Shimna River at the Ivy Bridge.
The return route to the car park proceeds along the old river drive passing Foley’s bridge and the dramatic Shimna Gorge before returning up the Green Rig.

Tollymore Forest Park – Mountain & Drinns Trail
Beautiful walk. Be careful not to miss the turn off for Drinns after the Hore bridge. Tough climb for 20 or 15 minutes but very satisfying to get there. Bit tricky at the very top- beware not to slip on the off trail section- but you soon get back on to the trail. At pace it can be done in roughly 2 hrs,20 but normally takes a bit longer. Great walk.
