Mt Hope Station caves

Closed to divers

In the 2005 report the leaseholder of Mt Hope Station did not allow divers. We found no later status (Oct 2026): don't go without the leaseholder's written permission.

The dive

More than twenty sinks, springs and resurgences on one property, some of them connected.

Restrictions that can't be passed, connections that exist only on paper and a shaft to 54 m with a restriction at the bottom. Remote, with no chamber on Santo.
Profile and sections

More than twenty sinks, springs and resurgences on one property, some of them connected. The best known, Three Way Spring, is a still blue hole of 11 by 8.5 m with one inflow and one outflow; the Eel passage beyond it can't be fully passed.

The leaseholder brought the caves to attention in 1994, they were first dived in 1996, and CDAA divers explored them until 2000. Many passages end at a restriction.

Practical: closed to divers since the 2005 report; we found no operator or expedition diving there now.

Depth and profile
Plan for 54 m: that is the depth of the shaft 2ES0023 ('54m Hole'), with a restriction at the bottom. Three Way Spring is 12 m deep.
Configuration
Many restrictions and passages that can't be fully passed: sidemount (estimate); backmount and CCR only in the larger springs.

How to get there

On the land of Mt Hope Station on Santo, only with the leaseholder's permission. One of the shafts (2ES0034) needs an abseil to running water.

Certification requirements, configurations and trimix depths are estimates for planning. Always check them locally and dive within your training. Compiled from web research (Oct 2026): the Vanuatu Tourism Office (diving guides for Vanuatu, Efate and Santo), Diveplanit on Big Blue Vanuatu, Divernet (2023 and 2024), Lonely Planet (2024), TravelOnline, Dive Worldwide, PADI, showcaves.com, Richard Harris's expedition report (2005), noonsite (2023), Diving and Hyperbaric Medicine (2006) and Outremers360 (2024). The dive operators' own websites could not be opened. Only Matevulu Blue Hole has coordinates from a source. The sea sites are guided boat dives into caverns and tunnels; certification and configurations are estimates.
