Pitt Spring We visited Pitt Spring where Econfina Creek is fed by a natural spring, creating a natural swimming pool of the purest, clearest water imaginable.The colours of the white sand and blue-green water were far more reminiscentof a Caribbean beach than anything I had imagined fresh water could be. At the heart of the pool is a small cave from which the springwater floods, ata constant temperature of 72ºF year round.
