• What to do on the beach, at night, and around turtle nests
• How to support sustainability beyond the shoreline with simple travel choices 

Quick actions that make the biggest difference: 

• Use designated beach access paths and avoid walking on dunes
• Leave the beach better than you found it before you head out
• During nesting season, reduce bright light after dark near the beach
• Use red-filtered lights for nighttime beach walks Give marked nests space and follow posted guidance

When you visit Hilton Head Island, we invite you to take the Promise to be IslandKind. It’s a simple way to help protect the beaches and wildlife that make our coast feel like home. 

Being IslandKind at the beach means:

• Respect wildlife: Give shorebirds, dolphins, and sea turtles room to do what they do. If you are close enough to change their behavior, you are too close.
• Leave no trace: Treat the beach like a shared backyard. Bring less, pack up what you bring in, and help keep sand and shorelines safe for wildlife.
• Protect sea turtles after dark: Keep light to a minimum so nesting turtles and hatchlings can find their way.
• Share the shoreline: Follow beach signs, keep sound levels considerate, and give others space along the waterline. 

You are part of our community while you’re here, and we’re grateful you’re helping care for Hilton Head Island. 

Below, you’ll find the practical steps that bring these IslandKind choices to life, from dunes and nesting areas to nighttime lighting.

Hilton Head Island draws many visitors every year for beach days, salt-air breezes, and wide-open coastal views. Visitors and locals flock to the beaches, but the shoreline holds a world of life if you take a closer look. Sand dollars, ghost crabs, and shorebirds all share this space. You might spot sanderlings darting at the waterline, or catch a glimpse of a piping plover leaving tiny tracks as it searches for its next meal.

These beaches do not stand alone. They connect with maritime forests and salt marshes, creating a natural network across the Lowcountry. Together, these landscapes help filter water, buffer storms, and create nursery habitat for coastal species.

Sea Turtles and Why the Beach Matters After Dark 

Loggerhead sea turtles, whose ancient lineage stretches back 100 million years, are one of the stars of our beaches. During summer evenings, female loggerheads emerge from the surf and carefully lay their eggs in sandy nests under starlit skies. When those nests hatch, tiny turtles scramble toward the glistening horizon, using natural cues to find the ocean. Bright artificial lighting can disrupt those cues, which is why nighttime choices on the beach and along oceanfront properties matter so much. 

Did you know? Just one in 1,000 baby sea turtles survives to adulthood, which is why Hilton Head Island takes pride in hosting over 300 nests annually, giving these young turtles the best chance to prosper.

Hilton Head Island’s shoreline is shaped by natural forces like tides, storms, and shifting sands. Like many barrier beaches, it also faces pressures that require thoughtful management and community care. The most common challenges include:

Coastal Erosion and Dune Health

Erosion is part of a coastal shoreline’s natural cycle, but rising seas and stronger storms can intensify the impact. Here on Hilton Head Island, we’ve responded to this challenge with efforts such as beach renourishment projects and dune restoration. Dune projects often include native plants like sea oats, which help stabilize sand through root systems that hold dunes in place.

Artificial Light at Night

When beachfront lighting spills onto the sand, sea turtles can become disoriented. During nesting season (May through October), the Island’s Lights Out ordinance is in effect, encouraging beachfront properties to shield or redirect their lights and adopt turtle-friendly amber LEDs.

Human Impact on the Shoreline

Even small habits add up on a busy beach. Litter left behind can harm wildlife. Holes dug in the sand can trap hatchlings. Walking across dunes can damage vegetation that holds the shoreline together. Hilton Head Island’s beach management approach focuses on education and practical support, including waste bins at access points, clear signage, and beach ambassadors who help visitors enjoy the shore responsibly. Local programs and partners also play an important role. Places and initiatives such as the Coastal Discovery Museum and the Sea Turtle Patrol help visitors understand what they are seeing and how to protect it.

Your actions make a meaningful difference in protecting our beaches. Here's how you can help preserve these special shores with a few thoughtful choices during your visit.

Use Dunes and Beach Access Points the Right Way

• Stick to designated beach access paths
• Avoid walking on dunes or dune vegetation
• Remember that dunes help buffer storms and protect the Island

Leave the Beach Better Than You Found ItTake all personal items with you when you leave

• Fill in holes and flatten areas that could trap wildlife
• Smooth out large sand structures near the waterline
• Use trash and recycling bins at beach access points

Follow Nesting Season Guidance, Typically May Through October

During nesting season, your choices after sunset are especially important. 

• Close curtains in oceanfront rooms after dark to reduce light spill
• Keep balcony lighting low or off when possible
• Use a red-filtered light for nighttime beach walks
• Avoid shining light toward the waterline

Give Turtle Nests Space

Marked nests are protected for a reason. Keeping distance helps ease stress on wildlife and protects hatchlings. 

• Stay back from marked nests
• A distance of at least ten feet is a helpful rule
• Do not touch stakes, tape, or signage
• Keep pets and bright lights away from nest areas

Beach protection is part of a bigger picture. The choices you make around transportation, waste, and where you spend time and money can support the Island’s sustainability goals.

Easy Low-Impact Travel Habits on Hilton Head Island

• Bring a reusable water bottle and reusable shopping bags
• Avoid single-use plastics, especially on beach days
• Choose accommodations with environmental commitments
• Explore by bike and use the Island’s extensive cycling paths instead of driving for short trips
• Consider joining a community beach cleanup if one fits your schedule
• Support local businesses that follow sustainable practices

These choices help Hilton Head Island stay beautiful, healthy, and welcoming in the long term.

Protecting our shores does not end when you pack up your beach towel. By making the IslandKind Promise, you can minimize your impact throughout your stay. When you return home, sharing a few simple conservation habits with friends and family who are planning their trips can help extend that care beyond your own visit. 

If you would like to get involved, local environmental organizations often welcome volunteers. The Sea Turtle Patrol and the Coastal Discovery Museum offer opportunities where your time supports the Island’s natural treasures. 

The privilege of enjoying Hilton Head Island’s beaches comes with a gentle responsibility to care for them. When we make mindful choices together, we help ensure that future visitors can enjoy the Lowcountry's abundant natural wonders.
