Meet the site
By name and location it is expected to be an area of large coral bommies or rock outcrops on the sand in the same 6–14 m depth band as the rest of Lighthouse Bay.
Lighthouse Bay reefs share a common character: limestone ridges, outcrops and cracks isolated in a sand desert, which act as a magnet for fish, turtles, sea snakes and reef sharks. Divers here can expect the same mix, and the site shares the bay's shelter from the prevailing south-westerly swell.
Confirm with Exmouth operators whether The Boulders is still in regular use and its exact location.
Planning notes: Open Water certification is recommended and the site is rated beginner. Expect to spend most of the dive around 10 m, with a maximum of about 14 m. Access is by boat only, and site selection depends on wind, swell and tide on the day. Best season: April–November (whale sharks March–July, humpbacks July–October, mantas year-round). Traffic: moderate (occasional charters/club dives).
Research this site before booking Stored site notes may be historical. These questions highlight gaps without turning old instructions into a current dive plan.
The Boulders (Lighthouse Bay) is recorded as Reef in Ningaloo – Exmouth. The listed access is boat (day trip). Confirm the actual meeting point, route and permission to visit; a map pin does not establish any of these.
Topics flagged by the stored research
These are questions prompted by the existing notes, not a verified or complete hazard assessment.
- Current and timing
- Ask how the operator assesses the current window for the actual route. Historical tide notes are not a departure instruction.
- Other water users
- Ask about vessel activity, exclusion areas and the agreed surface arrangements.
Historical access notes exist for this record, but have not been independently verified for current use. Request current directions from the operator or site manager rather than following an old entry description.
