Virginia is for lovers is what many locals are fond of saying in Virginia. Relive history here by attending a Civil War Reenactment, or visit the Museum of the Confederacy, home to the first White House of the Confederacy. For theme park enthusiasts, Virginia is also home to Busch Gardens in Williamsburg.
Personally I've never been to Massanutten but it looks like the average temp at that time is mid 80s. I'm not sure where you're from either but I wouldn't pack a jacket :)
The weather is sometimes cool, sometimes absolutely gorgeous. Massanutten is a pretty spot. Lots of color in October when the leaves change. This year has been gorgeous weather.
I've been to Massanutten in the late Summer, It is very warm then. There are a lot of things to see while you are there that aren't too far to drive. Nearby is Luray Caverns and Natural Bridge. I recommend these scenic sites. There are also wineries all over too.
