Scotland Camping/Hiking Guides?

Hello all,

I'm looking at planning a backpacking trip to Scotland in July. My hope was that I could find some sort of multiday hike/camp through the Highlands. I haven't found anything that is as hardcore as I'm looking for. Hike all day, set up camp, hike all day. 3-4 days max.

I would be going solo so it would be nice to find a group of like minded people to do this with. Let me know if anyone knows how to get into something like this.
