Excellent field to drop in for a bacon butty. There is no peri track or parallel taxyway, so if landing westerly you have to backtrack the active runway, which is a tad unusual (there is a 'layby' at the westerly end so you can wait for a gap in inbounds before backtracking).
When I first visited, it was just a grass strip in the valley bottom (Trehellig Farm, IIRC). Now much more upmarket, hence known as 'Welshpool International'
