My wife has agreed to a weekend camping trip for the family (2 children) for June 16-18. Our children are 10 year old daughter (camped & backpacked several times) and 5 year old son (will be his first trip). We are camping in a well established campground to make it easy on my wife and son. We are interested in a day hike that may involve scenic view, waterfalls, swimming holes, or any combination thereof.

We are looking into Grandfather Mtn State Park, but are there any other suggestions that may be a short (30 minute or less) drive from the campground?

Thanks!
