They also have three trails: a Life of Dunes, Life of Marsh, and a Forest Trail. At the Seashore Museum they will give you little booklets on each of these trails and the trails are so nice my husband was able to push me in my wheelchair on them.
But, the most fantastic part is seeing the wild ponies, which just wander the whole island. We saw them on a dozen different occasions, including just wandering by our campsite! Although you cannot touch them, they are wonderful to see, living wild and free.
