Camping is available in two specific areas around campus. The Premium RV camping area is situated on the quickest part of the track between Turns 11-12 and comes with all the essential hook-ups to ensure your comfort. There's also camping in Lot N, which is just a short walk from the Gate 3 entrance, close to Turns 3-4.
