I can send you the exact spots I wild camped if it helps you.
That be good mate if you can , the more advice and tips i can get the better i will be prepared lol.T:
Thought I'd post them on here so everyone can use them if they wanted to.
The 1st night
I parked behind the co-op in Golspie, free parking, public toilets (make sure you have some 50p's as it doesn't give change) and the co-op right near in case you need to buy any last minute provisions.
coordinates for here are 57.973801, -3.975153
2nd Night
I parked up on a lovely bit of grass just off the road with amazing views from the van.
coordinates for here are 58°31'54.9"N 4°47'27.7"W
3rd Night
This was the place where I filmed the time lapse video of the sunrise, if you get up early enough its amazing to watch the sun come up here, lovely little wild camping spot.
coordinates for here are 57°32'09.8"N 5°42'06.9"W
4th Night
This is off the course of the NC500 down on Skye, but it's an amazing little wild camping spot, plenty of wildlife about.
coordinates for here are 57°07'55.0"N 5°58'19.1"W
I will echo what JC1 has said, I love wild camping, aside from the cheapness of it you get to choose your view, my Mrs would consider it for one night max and then it's back to campsites so I can only do it on my own.
