HI Ed
Welcome to the forum.
What defines expensive fishing? I get a season ticket for the river on a council run beat and it cost me about £90, runs from Feb 11 to Oct 31st, i can go down any day i like except sundays and fish for as long as i like, this has to be a bargain

However the council look after banks, cut some of the grass and generally let the river look after itself, so it doesn't cost them much.
Now if you consider a fishery, which has to be stocked with expensive fish, most are lost to predators rather than anglers, so there is no return on that.
Then we expect tea/coffee, a nice hut for when it rains, perhaps boats which need looking after, there is constant maintenance so it looks nice, so we go back and then it also has to produce the goods when we are there or we get pissed off at having spent money and not caught owt

£14 is less than a round of golf at most golf courses unless you are a member (and that cost £100's at least)
All they have to do is cut the grass, no fish to stock and the only predators are rabbits and moles

.
sorry this might sound like a rant but i think the fisheries up here are actually very good value for money, i'd rather be down the river, but from october to Feb i have no other option if i wish to fish (and only have the option to fish up here because of them) unless you want a trip down for the grayling on the Tay system.
All the trout fisheries in and around Aberdeenshire offer top class fishing, depending on what type of surroundings you like and whether you prefer the bank or the boat, then there is something to suit everyone.
As for if you have Kids, most of the places have the grace to let Kids under 12, fish with a paying adult for free, so do some of the rivers, so i think they play very fair.
Any kid over 12 these days is no longer a kid

Many can outfish the grown ups, but they are in the game because they got the chance to try it without it costing Dad double (well probably not

)
I would suggest that if money is an option get yourself down the river once the season starts and perhaps only fish once a fortnight for the 'bows

Not trying to be cheeky you understand.
Practice is fun, and you can do it in the park with wool instead of flies, you'll find lots of help and advice at any of the fisheries in the area as well and thats always free

Have you tried anywhere yet?
