Travel a mere 20 minutes outside Baltimore, and you'll find a truly unique place: Quarry Lake at Greenspring. Although it's scenic on its own, it's an even more intriguing destination when you look at all its facets. Yes, it's Maryland's deepest lake — but it's also a mixed-use space with shops, restaurants, and picturesque trails offering one of the most tranquil nature experiences in the area. It's been two decades since the first business opened, and the center has expanded from there.
