2 Best Sights in Northeast Coast, Florida

Scientists surmise that, thousands of years ago, an underground cavern collapsed and created this park's most noteworthy geological wonder: a 500-foot-wide, 120-foot-deep sinkhole that's a designated National Natural Landmark. You can pack a lunch to enjoy in one of the park's picnic areas, and hike its nature trails. Guided walks typically take place on Saturday at 10 am. And you can bring Spot on a visit here, too; just keep him on a leash.

In this park, on a barrier island at the northernmost tip of New Smyrna Beach peninsula, 1½ miles of boardwalks leading to beaches and a fishing jetty crisscross sand dunes and delicate vegetation. Botanical signs identify the flora, and there are picnic tables and an information center. It's also one of the few county parks where pets are allowed (on leashes, that is).
