Staying Safe

  • Know your limits. Prepare for sun and heat. Wear sunscreen, insect repellent and appropriate clothing/hiking shoes.
  • Drink plenty of water. Your body quickly loses fluids when you’re on the trail. Bring a quart of water per hour of activity.
  • Tell others where you’ll be. If possible, avoid exploring alone. Tell someone where you are going and when you plan to return.
  • Wear a life jacket. The law requires that all children under age 13 wear one with adult supervision while boating.
  • Be careful in the boat. Upon entering or exiting a canoe or kayak, stay low, move slowly, and hold on to both sides of the boat.

Trail Etiquette

  • Trash your trash. Keep the park natural. Pack out all of your trash and Leave No Trace.
  • Leave feeding to nature. Feeding wild animals will make them sick and more likely to harm people.
  • Take only memories and pictures. Please don’t disturb or remove any of the park’s plants, animals or artifacts.
  • Primitive camping is allowed. Check with park HQ for information on areas where you may camp.
  • Horseback riding is allowed on the beach. Please check with park HQ for more information on where you may ride.
  • Keep pets on leashes for their safety, and to protect wildlife. We discourage pets on paddling trails due to alligators.
