Part of the new Castlewellan Walking Trails launched in November 2014, this trail is signposted from the Lakeside car park – follow the green waymarkers. This is also the Green / Easy mountain bike trail.
This relatively flat trail leads around Castlewellan Lake, a natural lake extended by the Annesley family early in the 19th centuary. With excellent views across the lake and the surrounding woodland the trail passes close to the Ice House and the iconic Castle built in 1856.
This is an ‘Easy’ walk suitable for most people in good health including those with limited mobility and some buggies. Surfaces are even and consistent throughout. The gradient is relatively flat.
This walk is situated in a working forest environment and may be subject to diversion and closure from time to time.
Up to date information is available on the Forest Service web site

Castlewellan Forest Park – Lakeside Walk
Stayed at the castle weekend past there and each night we would take the walk around the lake. It is brilliant a good enough distance for your heart to pump and the views of the lake itself and the mountains on background is really hard to beat anywhere else 👍
Just back from a weekend in Castlewellan Forest park campsite. Lake side walk was lovely, peace and quiet and at night a bbq and camp fire. Liked it so much we booked in for the next few weekends.
