Watling’s Blue Hole
An all-saltwater inland hole
About Watling’s Blue Hole
Most inland blue holes mix fresh and salt water, but Watling’s Blue Hole on south-west San Salvador is entirely salt water, so there must be an underground connection to the ocean.
Why it's on our list
- All salt water
- Inland
- South-west San Salvador
Opening hours, prices and seasonal openings change, so please check with Watling’s Blue Hole before you go.
