Tree Peaks is a boat-only Cairns day-boat site with no shore access.
Tree Peaks - Saxon Reef is a boat-only outer-reef dive east of Cairns with three shallow coral peaks rising from the seabed and concentrating marine life on the structures. The site is colorful in the shallows, with coral-encrusted bommies, ledges, and swim-throughs that make it easy to turn a simple day boat into a multi-level reef dive.

Key Hazards
Safety Notes
Ascend close to your vessel and deploy an SMB, especially because other operators may be present on neighbouring Saxon Reef sites. The site is shallow, but the boat-side traffic is the real planning factor.
Access Restrictions
No shore access is available; day boats and liveaboards depart from Cairns Marina and the transit to Saxon Reef takes about 1 hour 15 minutes.
Legal Notes
Treat the site as part of the Great Barrier Reef Marine Park and follow the relevant zoning and marine-park rules.
Community notes to help plan your visit.
Scuba Diving
Work the three peaks as a multi-level reef dive and spend time on the coral structures rather than pushing straight out to sand.
Freediving
The shallow peaks can work for experienced freedivers in calm conditions, but the site is better known as a boat-based scuba and snorkel stop.
Snorkeling
The shallow bommies and colorful top water make this a strong snorkel option on a calm boat day.
