Took a shot last summer and 'castle' was partly obscured by trees. Although not a real castle it's still a beautiful building. The University is lucky to have it within their grounds.
Does anyone have an idea what the track running west from Logie Kirk to Bridge of Allan, along the back of the university is like? It's marked as a cycle route on the Ordnance Survey, but I passed the entrance this morning and it looked really muddy - which is fine for mountain bikes, but rather less so for road bikes.
