Basically yes! we started at the strata florida and then headed north and based ourselves around snowdonia national park
Tips wise, spend some time checking out maps, OS is good in my opinion, we did quite a lot of road miles touring around but the roads and scenery are amazing so that was fine. If you're camping wild like we were (apart from the cabin we had use of) try and get to the area you want to camp in early-ish cos theres no guarantee you will find a good spot so you might have to look elsewhere and doing this in the dark is challenging!
We had an area in mind, basically we exhausted the maps of the area we had!
we tried to link byways with scenic road sections and points of interest like lakes or mountains etc, or food/pub stops
If anyone is planning a trip to mid/north wales feel free to contact me, I got a few routes and trails mapped and some awesome camping spots
