Lake George, while very scenic and very clean, is long and narrow compared to Winnipesaukee. There are a couple of rocky areas to watch out for and overall it was interesting and we felt like we had seen the whole lake in a short time.
When we went I could only find two launch ramps but that was years ago, sometime about 2002. Even so, I paid $60 to launch and park for one day. It gave me the feeling that they discourage outsiders!
Many years before that (1975) I trailered a 22 foot boat to Lake George and camped on an island at a state owned site. At that time you could pay for a site that came with a wooden platform for your tent and a fireplace. We were on an island with only two other campsites. You couldn't see the others unless you went looking for them so it was not crowded at all.
I just found this site. It was really inexpensive at the time we went.

I don't know if you were planning on taking a boat or renting one but I also found this Lake George Boating Guide:
