Visiting Nature Preserves



Delaware is home to 34 state-dedicated Nature Preserves, totaling approximately 7,000 acres of land. From the steep slopes of the White Clay Creek Valley Nature Preserve to the sandy shoreline of Beach Plum Island, there are exceptional natural features and unique areas to enjoy.

When You Visit

Not all nature preserves are open to the public, but you should visit those that are. Remember that these are special places that need to be visited in a manner that protects their natural and cultural attributes that qualify them as nature preserves. Therefore, here are a few guidelines for enjoying these areas:

  • Stay on the designated trails or public use areas.
  • Nature Preserves are “carry in, carry out” areas. Please take your trash with you.
  • Pets are not allowed in all nature preserves. If they are allowed, all pets must be on a leash that is six feet or less in length and their waste must be picked up and taken with you.
  • You should view wildlife from a distance. It’s safer for you and for the wildlife.
  • Do not pick up or collect any natural or cultural resource (plant material, feathers, rocks, soil, wildlife, fungus, insects, cultural artifacts). In other words, take only photos and leave only footprints.
  • Help prevent the spread of invasive species. Make sure your clothes and shoes are clear of mud and any potential seeds.  Check for and remove any mud, seeds, and unwanted insects (including adults, eggs, and larvae).
