I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission not required.
It can be a bit of a trek to the viaduct - I followed this guide:
Following the guide, you park in Catrine and walk along the Ayr River Way. There are a couple of fairly steep ups and downs to negotiate. They’ve had steps built (some of those are well over a foot high) but were a little slippery with the fallen leaves.
It’s possible to drive closer by turning off the A76, but it’s a farm road with no actual parking. It’s single track, but fairly wide and I did see a couple of people park up on the verge to take dogs for walks. I’ll stick a second parking marker in where I saw them, but I’d rather park in the Catrine car park and do the extra bit of walking.
TOAL was a little tricky because of trees. I walked a little way along from the viaduct until I found a break in the canopy and then hand launched/landed from there.
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 19/10/2024. It remains the responsibility of any pilot to check for any changes before flying at the same location.
