Glenariff Forest Park
This 1185 hectare (2928 acre) forest has miles of walking trails including the waterfall walk and scenic trail.
The waterfall walk is particularly lovely with footpaths leading you through steep wooded gorges with a series of beautiful falls to enjoy. There are some steep sections but it is a fairly easy climb and the footpaths are well maintained. There are some wonderful views of the surrounding area to enjoy from the high points.
The park is located in Glenariff County Antrim. There are good facilities with a car park, tea room and gift shop.
The Ulster Way long distance trail passes through the forest so you could pick this up to extend your walking. Heading north will take you to Breen Forest and the lovely Ballypatrick Forest where there are some nice waymarked trails to try.
