Since 1937, nearly 420 million people have visited the recreation area. The area has ranked among the top 10 most visited national park units since 1938. The last time the park welcomed 7.9 million people was in 2003. “We welcome the visitors, and we want them to have an enjoyable visit,” said Richardson. “If you’re planning a visit to the park, remember to be safe by wearing a life jacket in the water and recognizing your recreation limits. Our rangers are here to help you map out the best experience for you, so you can find your park.”.
