Ralph's Cave

The second entrance of the Dan's Cave System on Abaco, known for the translucent formations of its 'Glass Factory'. It lies in the South Abaco Blue Holes Conservation Area and is dived only with an approved guide.

Ralph's Cave is an inland blue hole on Great Abaco that was joined underwater to Dan's Cave, so the two now form a single system. Divernet describes an area called the Glass Factory, where thin translucent formations glow when lit from behind, along with crystal pools, a flowstone cascade resembling a frozen waterfall and formations tinted pink or red by Saharan dust.

The cave also preserves remains from when it was dry, including a bat skeleton reported to have lain there for more than 10,000 years. Like Dan's Cave, it is one of the principal sites of the South Abaco Blue Holes Conservation Area and is visited only on guided dives.

Highly decorated inland cave with fragile translucent formations; fresh water over salt water as in other Abaco inland caves.
