Public or private?
Public access
Who can visit: Open to the general public, including visitors, during permitted hours and subject to posted rules.
Entry route, fees & access boundaries
- Manager / access authority
- The Nature Conservancy manages the named destination. Ocean beach, lagoon facilities, hotel access and neighboring destinations are not interchangeable entrances.
- Access basis
- This listing covers a publicly managed beach access or park, not a private guest-only beach.
- Where to enter
- The Nature Conservancy and the named official visitor listing support a public visitor destination through designated entrances. Public access is distinct from present opening, protected-area closures and neighboring private parcels.
- Fees & reservations
- The suggested $2-per-person contribution is optional, with cash and credit-card payment; it is not a mandatory admission fee.
- Restrictions & exceptions
- Stay on marked trails. Picnics, grills, drones and collecting natural resources are prohibited by the preserve rules. Pets are not permitted at Blowing Rocks Preserve. Open 9 a.m.–4:30 p.m.; last entry 4:15 p.m. Closed Easter, Thanksgiving, Christmas Eve, Christmas and New Year’s Day. Check current manager notices before travelling.
- What this label covers
- Only the approved named entrance membership; outer boundaries and temporary operating status remain separate.
Beach ownership, the route across land, public shoreline-use rights and access to facilities are separate questions. Rules vary by state and location. Use the identified public entrance or documented permission; neither a nearby resort nor an admission fee by itself establishes that a beach is private. A mapped beach is not permission to cross private property.
Access policy reviewed 2026-10-03. Not a live closure report or a property-boundary survey.
Allowed & prohibited activities
Alcohol is not permitted in the preserve.

Water quality
Official beach bacteria testing · Florida Healthy Beaches
No direct named ocean sampling point is confirmed for this guide. No river or lagoon sample is substituted.
No usable dated laboratory snapshot is mapped to this guide. Use the official report link; no safe-water status is assumed.
A dated result is not available in this saved page.
Official Martin County results ↗ · About Florida Healthy Beaches ↗
What these results mean
Enterococci are bacteria used to indicate possible fecal contamination. Florida describes 0–35 per 100 mL as Good, 36–70 as Moderate, and 71 or more as Poor. These are periodic laboratory samples, not continuous monitoring.
The Beach Database checks the official report daily, but Florida’s sampling schedule is generally weekly or biweekly. The check time and laboratory sample date are different. Samples more than 14 days old are marked older; that reminder is not an official advisory threshold.
A nearby station is identified by name and distance. Its result is context, not a sample taken at this beach. Testing does not rule out all pathogens, harmful algae, sewage spills or other hazards. Follow current posted advisories and closures.
Crowd meter
The manager warns that lots can fill by late morning on weekends and holidays; arrive earlier and check the preserve before setting out.
