"As fascinating for children as it is for rock hounds, this geologic reserve is named for its string of massive pink-granite boulders that resemble a train of circus elephants. Estimated to be around 1.5 billion years old, the rocks are prime for climbing, but also feature carvings by miners who worked in the area during the 19th century. The best way to tour the park is via the Braille Trail, which was specially designed for visitors with visual and physical disabilities. Equipped with Braille signage, it winds through the main area of rocks and leads back to the ruins of an old railroad engine house—a remnant of the area’s quarrying history. When you’re done walking around, locate one of the picnic tables scattered strategically under shady trees and treat yourself to a picnic lunch."
