Yeah it was actually cold up there in mid july with mid 80s at base elevation. I had to put my hoodie on! The town of lake placid is beautiful. I enjoy it in the winter more than the summer, but in the fall it is truly special!
Here is a list of the 46 high peaks along with their elevations and how long it takes to hike them. Highest is Marcy at 5344'.
