If you had someone to show you, probably sooner, but you don't necessarily have to master it to catch depending on how wide the streams are. If you only need to get 30 or 40 ft into the river to get to where the fish are then working out a lot of line isn't an issue. You can make up a yarn rod and give it a try to get the 10 o'clock - 2 o'clock idea (I bet there are some sort of youtube tutorials...) and if you can get your hands on an outfit with line, leader, tippet (I use 4lb or 6 lb mono) go out to some open space and practice with some yarn on the end so you can see it. Be advised, small children will make fun of you if they see you fishing where there are obviously no fish, and some of them can be cruel. Whether fly fishing is a good option is best answered by the boss at the holiday camp, but if not you have nothing to lose by chucking something in, that loch is deep enough there could be anything in there, monsters.. Let us know how it goes.
