The Pool & Grotto unofficially opened on 7/17/04 with the general manager jumping in feet first. The official grand opening occurred at the 2004 End of Summer Party. The Pool is approximately 20' X 32' with the deepest point being 5'. The Grotto is 10' X 10' with bench seating on three sides. A spectacular waterfall cascades over the entrance to the Grotto and a 'faster than it looks' slide starts on top and comes around the side. Seven large palm trees and other tropical plants surround the Pool & Grotto.
The Cabana at The Pool & Grotto opened at the 2005 Summer Kick Off Party. The Cabana offers a private area for VIP guests of McPherson Beach to enjoy. The Cabana has direct access to the Pool & Grotto, features a sofa and bed for relaxing, and provides a scenic view of the entire beach.
The spring of 2017 saw an additional expansion of the The Pool & Grotto area. An outdoor shower, hot tub, fire pit seating area, and a new patio for lounging were added.
