I was at what would be a super venue last summer.
Glen Valley Adventure Centre in Co. Donegal.
They have a 4x4 course (in supplied bob-tail Land Rovers), clay pigeon shooting, climbing wall, archery etc.
There's also accomadation and a big car park which could be used for overnight.
The owner is a very friendly guy with an ecclectic collection of cars, diggers and tractors.
