If you like hiking, Walk Highlands is a stellar resource. Pick a region, sort by difficulty, get a step-by-step guide with photos and a map. Don't push your limits unless you're very experienced; our hills aren't big, but the weather can turn fast and in some regions (especially Skye, which is popular with tourists) the ground can be treacherous.

Edinburgh is a great city with a lot of history and fantastic architecture. Glasgow is the better base for trips into the Highlands and has more modern artistic stuff going on. If you're looking at Skye, you may want to consider Lewis & Harris instead, as it's a similar experience with far fewer people.

If you're near the Fife area, the boat trip out to the Isle of May is a great day out. Short ride from Anstruther to an island that is a seabird reserve these days, puffins and cormorants everywhere. Also get a fish & chips in Anstruther on the way back, it's some of the best going.

Depending on when you're going, the crannog centre by Loch Tay is worth a trip. They're currently rebuilding after a fire destroyed the original. It was/will be a reconstruction of a type of iron age home built over the water of the loch. If you're going up that way already, also stop by Iain Burnett's and get a chocolate tasting flight; he sells chocolate to the likes of the royals and I can believe it with how it tastes. The whole Loch Tay area has some fantastic hill climbs too. I did Ben Lawers last autumn, had a lovely day out.
