Castlewellan Forest Park

Castlewellan Forest Park covers 450 hectares of land lying north of the Mourne Mountains.

About the forest

The extensive area of woodland in this forest park is managed as a commercial forest together with other plantations in the area.

The variety of tree species is one of the most attractive features of the woodlands at Castlewellan.

Tree disease

There is an outbreak of the larch tree disease, Phytophthora ramorum. About 100 hectares of affected trees will be removed to help prevent the spread of the disease.

Much of the necessary tree felling has been completed and the forest remains open to the public. There is some restricted access to certain areas and paths within the forest to allow for safe access by timber haulage lorries. Visitors must pay attention to all health and safety signs and other signs displayed in the forest.

Before visiting, you should be familiar with biosecurity guidelines which help prevent spreading this disease. Find out more at the following nidirect page.


Castlewellan Forest Park caters for many outdoor activities including walking, caravanning and camping, horse riding and orienteering.

Special events can be arranged by permit. Guided walks are also available on application. Such activities may include sporting events or educational visits. To arrange a special event or activity, contact the recreation manager at Castlewellan Forest Park.

There are a number of scenic trails in Castlewellan Forest Park.

Lake Path and Leisure Cycling Route

(Blue trail - two and a half miles)

This path follows the shore of Castlewellan Lake providing good views of Slievenaslaat and Castlewellan Castle. Points of interest along this path are the Ice House, various sculpted features and the Autumn Wood. The Leisure Cycling Route follows this path.

Cypress Pond Trail

(Red trail - three and three quarter miles)

The first part of the trail follows the former stagecoach route, known locally as the Crow Road, where striking views of the northern Mourne Mountains can be glimpsed before reaching Castlewellan Lake.

There are delightful lake views heading to the Cypress Pond and the National Arboretum where a visit to the Annesley Garden is worthwhile. The return route to the car park offers expansive views of the lake, castle and the historic open parkland.

Slievenaslaat Trail

(Black trail - five miles)

Leading off the blue path, the black trail enters the mainly coniferous plantation where remnants of the Moorish Tower can be viewed. There are openings in the forest with impressive views of the farmland on and around Slievenaboley, Legananny Mountains and Slieve Croob.

Further east there are vistas where the lake can be viewed as the trail reaches its highest point by Slievenaslaat and the Mountain Lake. The return trail passes by the Winter and Annesley Gardens, open parkland, the lake and castle.

Parts of these trails are used for horse riding.

Shorter informal walks are possible around the garden area of the park.

Castlewellan Arboretum and Annesley Garden

The walled Annesley Garden, dating from 1740, provides a central focal point for the National Arboretum. This magnificent collection of trees and shrubs, set in beautiful surroundings, also incorporates fountains, ponds, ornamental greenhouses and broad sweeping vistas.
