Hetch Hetchy to Vernon Lake Loop in Mid July

My wife and I want to do a last minute trip and thought Hetch Hetchy to Vernon Lake loop my be a good one.  I have only been to the Hetch Hetchy region twice long ago.  Once in June - Mosquitos were horrible!  Once in August few rattlesnakes but overall not bad.

I don't think permits will be too much of an issue.

Anyone been in this area mid July?

If there is a link to another thread, please provide.  Did not see one.

Thanks,

Jeff
