You can camp at the bothy at Melgarve and/or,last year I noticed several quite nice spots between Melgarve and Garva Bridge and it was only the prospect of access to beer and proper food at the Monadhliath (has a new name but I can't remember what it is) Hotel that kept me going..
People often camp at Garva Bridge and I did once, then I found the toilet area........ just up (koff) stream (gip)(retch). I wouldn't camp there again.

Monarch Hotel might be the one Mike.

I've camped by Melgarve Bothy in the past - works for me.

The main reason is you can take a car,motor bike,cycle,with kit
for a month, right up to the door. I was there one weekend when
a wedding party of about forty, had it for the whole weekend.
Large tents the lot. As much food and drink you could eat.
The downside was vomit and crap everywhere." Some" did make
an attempt to clear it up and take away. Cheers.

I had a similar experience a few years ago. I arrived there from Glen Roy about 6pm, to find a young man unloading a crate of beer and a whole box of wine bottles from the boot of his car. He was perfectly civil, but declared his intention of drowning his sorrows all night following (I think) some relationship problem. My sympathies didn't quite extend to being a shoulder to cry on, let alone a clearer-up: the aim was solitude.

A lovely sunny June evening, so I kept walking, and eventually camped a few miles out of Fort Augustus after 10.30 at night!
