Glenshane Forest is a beautiful coniferous woodland located along the Glenshane Pass on the main road between Belfast and Londonderry. The forest features a large area of heather moorland and a beautiful babbling brook that runs right through it, the River Roe. Gorgeous location for a stroll with a fascinating touch of history too if you're heading to Priest's Chair.

The Priest's Chair, also known as the Glenshane Mass Rock is located just north of Bohilbreaga peak near Glenshane Forest and Eagle Rock. The rock got its name from an incident during The Penal Times. A young boy, acting as a lookout, deceived the searching soldiers, also known as The Red Coats, by pointing them in a different direction, protecting the priest and the mass rock.

It's quite an unusual experience stumbling into a pyramid in the middle of an Irish forest! This pyramid was built in the 19th century as a burial chamber for Lord Garvagh and is a lovelly feature to the forest today.
