The first impression was quite bad. Right after getting out of the car, we were surrounded by tons of mosquitos. We still went ahead, though, since we read somewhere that the view from the top was worth it. While walking, it was not so bad, but any stopping meant lots of mosquitoes all around us. Strangely enough, we did not find too many bites. The locals also said that usually there are a lot of black flies in the area but that this year was good, thanks to a cool spring.
I think this is a moderate hike since it is quite steep. But you can comfortably get to the top of this 1.7-mile trail in about an hour.
There's a publicly accessible fire tower at the top that you can get a great view of Lake Winnipesaukee and Lake Squam. There's also a picnic table available.
Compared to our other hike around the lake to Mount Major, I am not sure which one I would recommend more, since both were worth it. Mount Major was virtually mosquito-free compared to Red Hill.
