Burke's Beach is located off William Hilton parkway (278 Bus.) at Burke's Beach Road. The parking is very limited (13 metered spaces) but there is additional parking on the road or in nearby Chaplin Park where there are bathrooms and showers. Life guards for this area are seasonal during the spring and summer months. If there is surfing to be done on Hilton Head here is the spot for it.
Dreissen Beach Park
Dreissen Beach is also off William Hilton Parkway, at Bradley Beach Road. It has plenty of parking, rest rooms, sand showers and vending machines. It has a playground and a few picnic tables, one with a grill nearby. The boardwalk to the beach is quite long and requires healthy legs. If you park here, note the number of your parking space, go to the machine at the restroom facility to pay. There are 207 spaces which are 25¢ for thirty minutes but you can pay for a longer term. This beach is equipped with mats that make it wheelchair accessible.
Folly Field Beach
Folly Field beach is located on Starfish Road, a right turn off of Folly Field Road. Parking is somewhat limited (51 metered spaces at 25¢ per 15 minute period), but restrooms, sand showers and water fountains are available. This beach is also equipped with the mats that make it wheelchair accessible
Islander's Beach Club
As the name implies, this beach is intended primarily for locals. Parking is available only for those who purchase annual permits, which are limited to Hilton Head Island property owners. There is nothing other than that to keep visitors from enjoying this beach park - you can always have someone drop you off or go by bike. Amenities here include restrooms, changing rooms, a playground, soft drink machine, sand showers and a few picnic tables and are wheelchair accessible. It's located off Folly Field Road at Sparkleberry Lane (actual address is 94 Folly Field Road).
Fish Haul Creek Park
This is not usually considered a beach park because the beach is on Port Royal Sound, but this is Hilton Head's most pristine park, largely left to nature, with gigantic oak trees decorated with Spanish Moss. It has restrooms, a small pavilion with two picnic tables and a pier out into the tidal marsh. You can walk to a beach on the Port Royal Sound (about 0.3 miles from the parking lot), where clamming is popular. Truly wonderful for nature lovers especially birders, it's almost at the end of Beach City Road.
