Sailing along the beach, wind in my hair, sun on my face, watching the dolphins on a parallel race along the shore has got to be one of the more sublime memories I have of riding a bike in Hilton Head. It is closely followed by the sheer fun of mentally playing 18 - 27 holes of golf, while racing madly around the cart paths of the course at Ship Yard Plantation. Hilton Head Island is also covered with bike paths, also utilized by rollerbladers and walkers. It's fun for people of all ages and abilities. I have always rented from Pedals (great personalized service, new bikes that are well maintained), but there are many rental places on the island. It's a great way to see the gators and the rest of the wildlife.
