One island that has avoided the groynes blemish (and water breaks) is Bathala. As a result, the sandy beaches are completely exposed to and subject to the whims of Mother Nature. The resort is accustomed to regularly shifting beaches as the tide and wind moves beaches around the island. One of the villas seemed exceptionally close to the water’s edge when we visited and exposed roots of nearby palm trees made evident that the water line hadn’t always been there. The resort explained that such shifting was quite common for Bathala and they monitor the edges carefully, but in general fluctuating circumference stays within acceptable tolerance to not threaten the infrastructure.
Heraclitis famously remarked that "No man ever steps in the same river twice.” At Bathala, one doesn’t visit the same beach twice.
