Blowing Rocks Preserve is one of four campus preserves under TNC Florida’s Center for Conservation Initiatives, advancing conservation through education and training, outreach and volunteerism, science and research, and land stewardship. Learn more.

Visitor Notice:

Many of the rocks on Blowing Rocks’ shoreline are not currently visible because they are buried by sand. Sand has been building up on our beach for the past few months. The Nature Conservancy did not add sand to the beach. Over time, waves will carry the sand back out to sea and the rocks will once again be visible. This is a natural process and we do not have a timeframe of how long this will take. This information will be updated as the shoreline changes.



After six decades of protecting Florida’s great places, TNC considers Blowing Rocks Preserve one of our proudest achievements. This peaceful, barrier island sanctuary is a well-known model for large-scale, native coastal habitat restoration.

The natural features found here are disappearing fast from many Florida islands, and a number of endangered plants and animals call this special place home—including rare loggerhead, green and leatherback sea turtles.

The preserve was named for its rocky Anastasia limestone shoreline—the largest on the Atlantic coast. At high tide when the sea is rough, seas break against the rocks and force plumes of saltwater up to 50 feet skyward. It’s an impressive sight. What exactly are the blowing rocks?




Open seven days a week from 9:00 a.m. to 4:30 p.m. The preserve is closed on Easter Sunday, Thanksgiving Day, Christmas Eve, Christmas Day and New Year's Day.


Enjoy swimming and snorkeling from the protected beach. Observe rare birds, plants and animals on three hiking trails.

  • The beach and ocean conditions at Blowing Rocks Preserve are always changing and might look different each time you visit!

    Typically, summer months bring calm, clear waters that are excellent for swimming and snorkeling. Winter months tend to bring rough seas and larger waves that cause the “blowing” action, when large waves crash up against the rocks. What exactly are the blowing rocks?

    If you want to time your visit to observe this impressive sight, there are two factors to consider:

    1. Is the sea rough or calm?
    2. Is it high tide or low tide?

    Your best chance to observe the “blowing rocks” is to visit on a day with rough seas at high tide. The time of high tide is different each day—check the current tide schedule. Please note that our hours of operation do not change depending on the tides.

    • Bring a reusable drink bottle(s).
    • Pack snacks in reusable containers or bags.
    • Charge your camera so you can capture interesting sights, taking only memories and leaving nature intact.
    • Protect yourself from the sun by wearing a hat, SPF clothing, sunglasses, and/or reef-safe sunscreen. Learn more about reef-safe sunscreen and other ways to #RespectOurReef.
    • Pack in, pack out—if you do have waste, be sure to collect it all to properly dispose of it before leaving or once you have returned home. Bins for recycling and trash are available onsite.
    • Keep a safe distance from wildlife. It can be dangerous for wildlife to be fed, touched, chased, or crowded.
    • Have fun at the beach but be sure to fill any holes and flatten any sandcastles when you’re done to prevent dangers to sea turtles.
    • Before you leave, rinse or brush yourself and your gear off to prevent species from traveling to new habitats.
  • We offer a number of ways for you to get involved with learning opportunities, immersive experiences, and volunteer service activities such as Shoreline Cleanups, Sunrise Sessions, Guided Tours and an annual Winter Lecture Series.

History of Blowing Rocks Preserve

Blowing Rocks Preserve was born in 1969 when the forward-thinking and generous residents of Jupiter Island donated 73 acres of the barrier island to TNC. The donation started when developers petitioned the Town of Jupiter Island to change the land’s zoning from single-family dwellings to high density apartment buildings or hotels due to the scenic rock ledges along the shoreline. Local citizens had an unfavorable view of the plan. The developers’ application was denied and, thanks to the persuasive efforts of Nathaniel Reed and other residents, the developers agreed to abandon their project and sell the land to the residents. The residents then donated the land, creating Blowing Rocks Preserve.

In the early days of the preserve, one of the biggest challenges was shifting the frequent, unregulated public use of the area to a managed preserve environment. This meant limiting vehicle traffic and abandoning the old road that ran atop the beach dune. In the 1980s, the preserve entered a landmark period of native habitat restoration. This pioneering project started in 1985 by removing large Australian pines on the preserve dune. In 1987, a massive restoration effort resulted in removing 500 Australian pines and planting 14 acres of native saltmarsh, mangrove, coastal strand, and tropical hammock on the east side of the preserve.

The massive habitat restoration provided the ideal platform to share TNC’s expertise in restoring and managing coastal systems with other conservation professionals and scientists. As staff planned the restoration for the west side of the preserve, they engaged in another novel undertaking and invited volunteers and community members to assist. The goal of this initiative was to build a greater awareness and sense of responsibility for the environment amongst the local community.

Over the next 15 years, more than 3,000 volunteers and community members contributed 78,000 restoration hours. Part of their work included reconnecting the preserve to the Indian River Lagoon, which had been altered by past dumping of dredge spoil from the Intracoastal Waterway. Volunteers helped install and repair 12 tidal culverts, creating ¾ mile of tidal creeks and four small tidal ponds. They also helped remove 4,000 Australian pines and thousands of Brazilian peppers and other invasive species. This made way for 15,000 native plants grown from seed in the native plant nursery at Blowing Rocks, which we planted onto the preserve grounds.

As an increasing number of volunteers and visitors were visiting Blowing Rocks throughout the 1990s, staff identified the opportunity to provide public outreach and share the importance of the fragile native habitats found at the preserve. TNC placed educational signage along preserve trails and at the beach overlook to highlight native species, including the endangered sea turtles that nest along the ocean shoreline.

One evening, the Reed family (longtime supporters of Blowing Rocks) and philanthropist Rosita Hawley Wright observed nesting sea turtles at the preserve. Mrs. Hawley was so overwhelmed by the experience that she made a lead gift to TNC to construct the Hawley Education Center that now houses staff offices, a public exhibit gallery and the Nathaniel Pryor Reed Classroom. The Hawley Education Center hosts public lectures, workshops and trainings for Conservancy staff members and partner organizations and agencies.
