Area can get quite popular as Brecon Mountain Railway runs nearby. Also, water sports are popular on the reservoir itself.
The originator declared that this location was not in a flight restriction zone at the time of being flown. It remains the responsibility of any pilot to check for any changes before flying the same location.
I’m going to guess you meant Bala. That’s North West Wales and whilst I love the area I don’t know it well, certainly not for drone flying. But quite a few drone shots / vids I’ve seen from Angelssey for starters.
I will add that there are lots of lakes, etc up that way and sunset / sunrises could be stunning.
Llyn Ogwen is one I’ve been to with my camera hoping for a sunrise - easy access from the road - as it lies east / west. The sunrise didn’t happen but instead I strolled up to Llyn Idwal via the footpath to the left of the info / cafe in the car park. Took about 30m and I was totally on my own for ages…
