This beautiful riverside valley bottom, located below the town at the base of a shimmering waterfall, has two sinkholes, known collectively as Blue Hole. Full of crystal-clear water, they offer refreshing dips. If driving, turn right straight after NCB bank on the main street, then take the first left around a blind corner, then the first right. Park by the second left and take the path down to the river. It's a 3km hike from Christiana's main street; ask locals for directions.
