Dive with a local operator for site selection, navigation, and surface support, especially on wrecks and channel-current days.
Use a surface marker buoy on ascents and stay clear of the ferry route and busy traffic corridors.
Expect variable visibility. Agree on close buddy positioning and consider torches even on daytime wreck dives.
For deep wrecks like Principe de Asturias, only dive with appropriate training, redundant gas planning, and conservative go/no-go decisions based on sea state and current.
Snorkelers and freedivers should use a float and flag and avoid exposed points when there is swell.

For any suspected decompression illness or serious injury, seek medical evaluation immediately and call local emergency services.
Ilhabela has local medical services for assessment and stabilization, but advanced care may require transfer to the mainland (Sao Sebastiao, Caraguatatuba, or Sao Paulo depending on case severity).
If you carry dive accident insurance (for example DAN), contact their emergency hotline as soon as practical after calling local services, so they can help coordinate care and transport.

The Sao Sebastiao Channel is a working waterway. Use surface marker buoys, obey dive-flag rules, and avoid freediving or snorkeling in traffic lanes without dedicated support.

Summer downpours can reduce visibility in a matter of hours. Keep dive plans flexible, accept site changes, and consider macro-focused dives when the water is green.

These tiny insects are infamous in Ilhabela, especially near vegetation and at dusk. Bring strong repellent, light long sleeves, and treat bites early to avoid irritation.

In cooler months, weather can flip quickly with cold fronts. Plan backup land activities and do not overpack your schedule with non-refundable boat trips.

Ilha das Cabras is a municipal submarine ecological sanctuary protected from hunting and underwater fishing. Treat it as no-take: do not collect, do not feed wildlife, and maintain excellent buoyancy to avoid contact with the bottom.
In Parque Estadual de Ilhabela, stay on marked trails, respect access limits (for example the Castelhanos road rules), and pack out everything you bring in.
Use reef-safe sunscreen, secure all gear to prevent marine debris, and avoid chasing turtles or dolphins for photos.
If you add a trip to other protected areas in the region (such as Alcatrazes), only go with authorized operators and follow all briefing rules on distance, anchoring, and group control.
