Not a camper, but I've heard good things about The Glen Brittle Camp Site, certainly location wise much nicer than the camp site at The Slig.
And if you need some pub grub just ride up the glen, turn left and pop into The Old Inn.
Bing maps is handy by the way - click on the OS map option and zoom in.

DJ bear in mind a polarizer robs you of two stops of light. Also full effect at 90 degrees to the sun, no effect at 0 degrees, and yeah you need some good sunlight. Handy for taking reflections out of water, turning the sky a natural deep blue etc. Fiddle about with it and you'll get the idea.
Most of these snaps were taken with a little Panasonic G1 bought when it was discontinued. I used the kit lens for a while, then got their fancy 12-35 f2.8 And the other year I grabbed a heavily discounted Panasonic G3 just after they announced the G4 model.
Basically it's an SLR without the pentaprism and mirror. Has a 4/3rds sized sensor, so a physically decent sized sensor for a wee camera. Ideal compromise for walking etc I figured.

My old G1 with 14-45, Canon 5D with 24-70f2.8 and GH3 with 12-35f2.8 (equivalent to the Canon 24-70)
