Las Gatas

During our first visit to Zihua, about 20 years ago, we took the water taxi over to Las Gatas. Walking along the beach, there was someone at each restaurant trying to get us to come in. We finally arrived at Otilia's, at the far end, and out came Franco, the waiter, and asked if we wanted to sit down. Being totally clueless about protocol, I asked whether we were expected to pay rent for use of the furniture. "Only if you want to" replied Franco. That really cracked us up and we've been going there ever since.
There are, indeed, some rocks in the sand, but it's the lest likely place to get crowded. We don't go there on weekends. If you want to snorkel, swim to the bay side of the reef; you'll see more.
