Blowing Rocks Preserve's Turtle Season Isn't Winding Down. A Record Year Means It's Running Late.
"The Anastasia limestone that makes our beach so beautiful can create a challenge for turtles." Preserve manager Cristin Krasco has said as much about Blowing Rocks Preserve, and by late August most years, that challenge has mostly worked itself out. The rock ledges that draw photographers every winter for their geyser-like blowholes have, by now, usually released most of the season's hatchlings out to sea. This year, the crevices are still busy.
Florida's sea turtle nesting season runs from roughly the start of March through the end of October, and by the numbers reported through the Florida Fish and Wildlife Research Institute, 2026 is shaping up to be one of the heaviest on record. Loggerhead nests statewide hit 94,667 by June 30, the highest end-of-June count logged in the past five years. Leatherback nests reached an unprecedented 2,152, a potential record if confirmed. That data matters to anyone who walks past Blowing Rocks Preserve on a regular basis, because a season that heavy on the front end produces a longer, heavier hatch-out on the back end, and this stretch of Jupiter Island shoreline carries more of that traffic than most people realize. More than 600 turtles lay eggs along the preserve's mile of beach in a typical summer. When the statewide count runs long, so does the local one.
The preserve exists at all because Jupiter Island residents intervened directly in its fate. In the 1960s, developers petitioned the town to rezone this stretch of barrier island from single-family use to high-density apartments or hotels, drawn by the same dramatic rock ledges that make the beach worth protecting. Local residents pushed back, and with conservationist Nathaniel Reed helping lead the effort, the developers abandoned the project and sold the land instead. Residents bought it and donated all 73 acres to The Nature Conservancy in 1969.
That history is why the limestone is still there, and why it still complicates every hatch. The Anastasia Formation running through the preserve is the largest limestone outcropping on Florida's Atlantic coast, and its erosion pattern leaves behind exactly the kind of crevices and solution holes that trap hatchlings mid-crawl. TNC staff and volunteers have patrolled the beach every morning during nesting season since the early 1980s, acting as informal lifeguards for turtles that get stuck before reaching the water. In a typical year, that patrol helps more than 100 hatchlings complete the trip. A record nesting year does not change the terrain. It just means more mornings this fall where staff are working nests loose from the rock rather than watching them clear on their own.
The preserve's operating rules do not bend for any of this, which is worth knowing before a fall visit rather than after driving out. Hours run 9 a.m. to 4:30 p.m., seven days a week, with last entry around 4:15 p.m., regardless of tide conditions or nesting activity. That means the preserve is closed well before dusk, when hatchlings actually emerge and crawl, and any after-hours patrol work happening on the beach is TNC staff and permitted volunteers only, not something open to a public visit.
A handful of other rules stay constant no matter the season:
What is different this fall is how long the roped-off nest sections stick around. Small marked areas flagged by volunteers are a normal part of any Blowing Rocks visit between March and October, but with more nests laid later into the summer, expect more of the ocean-facing beach to carry those markers into September and even October, past the point when a typical year has already cleared out.
Blowing Rocks Preserve is really two experiences divided by South Beach Road. On the ocean side, the Beach Trail runs a tenth of a mile through shaded maritime hammock to the main staircase, and the Dune Trail continues four-tenths of a mile atop the beach dune with a second staircase along the way. This is where the marked nests concentrate, and where a fall walk means working around flagged sections rather than having the shoreline to yourself.
Across the road, the Indian River Lagoon side stays largely unaffected. A 300-foot elevated Mangrove Boardwalk, wheelchair accessible, leads to an overlook of the lagoon, and the Lagoon Trail loops another four-tenths of a mile through salt marsh and coastal strand. A shorter Pollinator Garden Scenic Walk rounds out the network near the Hawley Education Center. For anyone who wants a walk without navigating roped-off sand this time of year, the lagoon side is the practical answer, and it sits a few hundred feet from the beach side rather than requiring a separate trip.
The Hawley Education Center itself has a specific origin worth knowing. It's named for Rosita Hawley Wright, a philanthropist who, along with the Reed family, witnessed nesting sea turtles at the preserve one evening and was moved enough by the experience to fund the center's construction. Today it houses the "Tides of Life" exhibit and the Nathaniel Pryor Reed Classroom, and it remains the starting point for the preserve's guided nature walks.
That last detail is where a visitor should double-check before planning around it. The preserve's own communications this year list guided walks on different days depending on the source, and rather than commit to a specific day here, the more reliable move is calling the preserve directly before showing up expecting one. Visitors can also contribute directly to the season's data, logging sightings through iNaturalist, adding photos to the preserve's Chronolog Station, or pitching in on cleanup through the Beach Bucket Station. In a year with more nests to track, that kind of small, direct participation carries more weight than usual.
Most descriptions of Blowing Rocks Preserve treat it as a fixed attraction, the same rocks, the same tides, the same photo opportunity every year. What the 2026 season shows is that the preserve is not static at all. A statewide nesting surge changes what's actually happening on this specific mile of shoreline, week to week, well past the point most visitors assume the season has quieted down. For anyone living on Jupiter Island, that means the preserve down the road is worth checking in on through the fall, not just circling back to once the calendar says the season is over.
If you're weighing what long-term life on this stretch of the island actually looks like, month to month rather than just in the brochure version, Illustrated Holmes spends enough time on this coastline to talk through it directly.
