Grayson Highlands State Park Professional Review and Guide
"Virginia's highest state park, Grayson Highlands, lies adjacent to Mount Rogers (5729 feet), Virginia's highest point, and ties together a unique collection of flora and fauna. A highly versatile recreational area, the park is one of the most picturesque spots you'll find in Southwestern Virginia. You're likely to encounter some of the wild ponies that live and roam in the park year-round or catch the blooming of the Catawba rhododendron in the middle of June.
Visitors are encouraged not to feed or spook the ponies, but they are relatively calm and will gladly pose for a photo. The large light pink bloom of the Catawba explode during the hot summer months and are accentuated by their cluster of shiny oval shaped leaves. The aroma alone is worth the trip. Most of the Catawbas are around four feet high, but they can grow in excess of eight feet. Trail Surfaces: Flat sections, smooth up hills, and wet rocky down hills."
