Blue Beach (Navy name)
Fishing, snorkeling, paddle boarding, kayaking
Bathroom at #4 and another one on the main road before it turns to gravel
No sand, only rounded stones and broken coral.
The water is usually crystal clear and beautiful.
La Chiva is a long set of southside beaches accessed off of Route 997. Enter the Vieques National Wildlife Refuge at Garcia Gate and drive straight until the road changes to gravel, then drive some more. Eventually, the road will fork to the right and you will see the numbered signs on the right, starting with #1. These are entrance points for parking and access to the beaches. Find one that suits you and enjoy.
La Chiva #1 is a small rocky cove with beautiful clear water. Not really a beach per se (there is no sand only broken coral and large pebbles), but a quiet cove for snorkeling or maybe paddleboarding.
There is no shade here so plan accordingly for that.
