If you're looking for something a bit longer then the smaller strips on the west coast of Scotland are a must.
Coll, Collonsay, Oban, Glenforsa & Plockton are all gems.
Depending upon what you are flying you might also wish to consider Bute and Gigha.
The are also the bigger airfields such as Islay & Tiree.
Spring is usually the best time for the weather.
