Before you go
Questions, answered
How venomous are the animals we might see?
Very. Every guest attends Serpentine’s safety briefings. We maintain spacing, use spotters, and never free-handle venomous species.
What fitness level do I need?
Humid 8–12 km days with elevation, sometimes at night. If you overheat easily or have mobility limits, ask for a screening call first.
Can I fly a drone?
Only where national park rules and Serpentine permits allow. Default assumption is no until cleared.
How do I book?
This departure is hosted with Serpentine Expeditions; deposit and contracts flow through their systems.
