Always wanted to swim out to pic related nice and early, beat the crowds, and vibe. Now you can't do that, because instagram whores ruin everything, and I have no interest in hopping on an overcrowded boat for an in and out experience without ever setting foot on the sand. Any similar caves/places in the Algarve/nearby regions? I'm a competent swimmer and kayaker, so I'm not put off by a fitness/mobility requirement.
