The Castlewellan Touring-in-the-Trees site is a woodland camping and caravanning facility set within Castlewellan Forest Park, a 450-hectare park in County Down, Northern Ireland, lying north of the Mourne Mountains.

The site originally operated under the Northern Ireland Forest Service before transferring to Newry, Mourne and Down District Council on 1 January 2025. The park setting features tall, mature trees alongside a lake, with views of the castle.

Pitches include both tarmac and grass options, and the wider park supports a range of outdoor activities including walking, cycling, horse riding, fishing, canoeing, and orienteering.

Toilet and shower facilities, including wheelchair-accessible options, are available on site.
