Castlewellan Forest Park: Lake, Arboretum and Mitchell's Lake Circuit

Start at the public lakeside car park in Castlewellan Forest Park, reached through the signed park entrance off Main Street. This circuit combines the level lake walk with the longer Annesley Garden woodland loop towards Mitchell’s Lake. Follow the south shore past the Ice House, round the western end of Castlewellan Lake, then return along its north shore.

Back at the eastern end, take Lime Avenue uphill beside the arboretum and Annesley Walled Garden. Continue on the pink waymarked woodland trail towards Duck Pond and Mitchell’s Lake, circle the smaller lake, then descend on the western forest path to the lakeside parking area. Keep to the walking trail at mountain bike crossings and follow local waymarkers. The private castle conference centre is outside this route.

Allow about 2 hours 45 minutes for the roughly 7.5 km circuit. The lake section uses broad compacted paths; the upper woodland loop adds sustained climbs and descents, uneven ground and loose material. Wear grippy walking shoes, especially after rain. This is a working forest, so obey any temporary closure or diversion signs and watch for forestry traffic, cyclists and horses.

Car parking charges apply. Toilets are at the Grange area; check current catering availability during the ongoing Grange restoration. In October the park opens 9am to 6pm and the walled garden 9am to 4pm, so allow time to leave before gates close. Dogs must be controlled, with leads in the walled garden. Garden entry is an optional visit rather than extra distance included in this route.
