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…
If you have a FB account then I posted that image to my public pics page here:
For Pontsticill, I can reccomment the Red Cow pub, 5 minute walk from the dam; not posh, but friendly, good beer, and decent food! Dwr Cymru, who are responsible for reservoirs in Wales, do not permit TOAL on their land, but of course nothing prevents you overflying. I agree that this location is better in winter so long as the weather is decent, less crowded and usually more water in the reservoir for that plughole spillway! April should be fine…
The immediate Bala area is pretty much free of FRZs, but keep an eye out for RAF low-flying training with fast jets. In the immediate vicintiy of course Bala Lake deserves a flight, and slightly further afield are the big reservoirs of Llyn Celyn and Lake Vrynwy (please flush, Liverpool needs the water). Subject to the weather, your boots, and how fit you are feeling, Cadair Idris is a short drive away and the scenery up there is full-on phenomenal, as are the views on a clear day.
The Mach Loop is not far away either if you are interested in that sort of thing, but one is asked not to fly drones while the fast jets are about. Mountains everywhere, plenty of places to fly, some proper wilderness in the area southeast of Bala, but the coast north of Barmouth is subject to airfield and military FRZs. The seriously big mountains around Snowdon/Yr Wyddfa are about a half hour drive.
