Planning a vacation to Scotland and need advice

I am currently planning a vacation to Scotland and I am looking for something isolated, and also close to a place with plenty of nightlife.

Yes, I know these are a bit of a contradiction to each other, but I thought I would reach out and see if anyone has any suggestions.

I would like to visit some of the more remote highlands during the day and then find a good selection of bars and pubs at night.

If I had to puck though, I want the isolation. I am going to be on vacation and would rather get away from it all than be in the middle of everything.

Thank you all in advance.
