If you want to get out of Edinburgh for a day or two and see some other parts of Scotland, I recommend this company which runs mini-van tours. We took a 6 day tour of the highlands and Island of Skye and it was great. Sixteen people max with a Scottish driver/guide who was amazing. And the best part was that the group didn’t all stay together at night. They booked you into your choice of accommodations and many meals you were on your own.
You probably don’t want to do a longer country tour but even a one tour trip out of the city is worth it:
