Although the castle may be mysterious, it is not worth the visit. In order to be able to see the castle, you have to trespass on private land--yes, there are cameras--for only a short glimpse. If the castle were open to the public or if there were more information about it, then the stop would be more worthwhile.
The Puckerbutt Pepper Company is a small store located in downtown Fort Mill. It sells merchandise, mustard, hot sauce, and other delicious treats filled with some of the hottest peppers in the world. If you're feeling brave, you can try the flavors before bringing them home. If the spice is too much, just remember that the restaurant down the street sells delicious milkshakes!
Visiting the Butterfly Rainforest was an awe-filled experience. From the walls covered in preserved butterflies from across the world to the greenhouse that contains thousands of beautiful live butterflies, this is an extraordinary place to see for all ages. Aside from the butterfly greenhouse, the Florida Museum of Natural History also houses butterfly incubators, lepidoptery labs, and a constantly-changing exhibit area. When my husband and I visited, it housed Clyde Peeling's Reptiland which had frogs, toads, snakes, and fun facts about each. Overall, it took us about 2 hours to enjoy the entire museum. Definitely check it out if you have the chance!
Plan to spend at LEAST 2 hours if you visit this site! Sprawled across a few blocks are MLK's home, museum, tomb, and center for nonviolent resistance. There are a hundred plaques to read and a lot of rich history to learn. Although MLK is the main attraction, there are also galleries devoted to Rosa Parks and Ghandi. If you are in the area, I strongly advise you to visit these historical sites.
The New River Gorge is a gorgeous place to stop, learn some history, check out some gorgeous views and stretch your legs. I would not recommend this place as a day trip but, as a stop on a larger escapade, it is truly fun and magnificent!
The Audubon Nature Center is an exceptional addition to any road trip. The interactive displays, rescued animals, and knowledgeable staff set the Audubon Nature Center apart from the many other environmental information centers. Always, always visit if you can!
