Congaree National Park is home to the largest patch of old-growth, bottomland hardwood forest in the country and contains some of the largest trees in the Eastern US. Trees in this place regularly tower over 130 feet and some are over 160 feet tall. The park is a flood plain for the Congaree River and floods many times during the year. When the park is dry, it makes for some excellent, easy hiking, albeit in the company of many mosquitoes. Trees here include the impressive Loblolly pines, oak, bald cypress and many others. The loblolly pines are some of the tallest and can have a circumference of up to 10-15 feet. The bald cypress trees are famous for their knees which stick up from the forest floor.
