We went twice in one week. The visitor center is a nice first stop. Lighthouse is at the upper (northern) beach with picnic tables (gnats drove us away from lunch there, however, early March). You can find some shells, but had better luck last year. Saw some people on horseback. Not crowded at all; plenty of room! I explored only a small bit of trails; looks great if you want to hike or bike. The road into the park is also beautiful.
