Bottle Houses are at 6891 Hwy. 11 (North Cape Coastal Dr.). Three fanciful buildings are made of more than 25,000 glass bottles of various shapes and sizes. Visitors can walk through a chapel, a six-gabled house and another structure—all built with bottles. The surrounding grounds feature a Garden Interpretation Center set up in a replica of the Cap Egmont Lighthouse, rock gardens and more than 250 varieties of flowers.
