Before you arrive
Access notes
No solo diving; remain within certification and current park limits Confirm current rules, hours, water level, visibility, fees and emergency plan directly before travel. Cave penetration is not recreational open-water diving. Present required certification, register or obtain permission where applicable, use a qualified buddy team, and confirm current flow, visibility, closures and landowner or park rules.
Plan within your training
Conditions and hazards
Cold-water exposure, changing visibility and water level, current or flow, submerged timber/rock, entanglement, wildlife, difficult entry/exit, and separation from the surface. Any overhead or technical route adds loss-of-line, gas, depth, decompression and rescue-limit hazards. Permanent overhead, no direct ascent, darkness, silt-out potential, restrictions, line entanglement, high flow or siphon conditions, complex navigation, gas-management demands and possible decompression obligations.
Independent resource notice
This record is a starting point for independent verification. Access, closures, moorings, weather, currents, depth, visibility, operator availability, and site conditions can change without notice. Confirm current information with the responsible operator, property owner, managing authority, or another qualified local source before planning or attempting a dive.
