Scotland sites - off season.

[Tucker303]

Dear All,
Firstly, thanks to all those who post useful things here.
This is my first post and I've found it useful reading all of your comments and ideas.

I live in Glasgow and often go away for the weekend in my Cali during winter.

A friend is visiting from Australia in early March, and i was thinking about a longer trip.

Does anybody have any tips for campsites that are DEFINITELY open in the highlands and islands from March onwards / all year round?

I did find this site:
http://www.scottishcamping.com/

But there's no advanced "search by opening time" function.

I'm thinking Western Isles & Skye or some such....

Cheers!
