I've been going to the beaches at Sea Isle since I was a baby. The beaches are really nice and hardly get crowded. This might be because you have to purchase a "tag" to enter the beach. The town however gets really crowded during the summer and you might drive around a while looking for a parking spot that doesn't have a yellow painted line! The town has a nightlife, which is usually focused around the college crowd. Things can get rowdy at times, but generally its a small beach town with a little action!
