For about 45 minutes boat ride, you can experience swimming at the Marietas Islands- a sanctuary of the Blue-footed boobies!
My daughter and I went swimming at the Islas Marietas. Besides us, there is also one family in the island swimming with us.
The only huddle we had going there was the presence of strong waves hitting the rocks and getting to the two small beaches. I was watching my daughter so she won't get swept away by the strong waves!
This beach is not really recommended for swimming. It is more recommended for diving and snorkelling.
I compared the beaches of Punta de Mita to the beaches at the "Hoteles" in Puerto Vallarta, the sand in Punta de Mita is much softer and whiter.
Also, the beach is cleaner with fewer people and tourists. The water is mint green instead of brownish color!
In Puerto Vallarta, there are three rivers that flow to the ocean so that when it rains in the afternoon, all that siltation coming from the hills and mountains go down to the river and return flows to the ocean. The result? The ocean gets dirtier! You can see flowing branches, foliage, etc. going down to the ocean.
There is actually a surf club in Punta De Mita- just in case you are interested. Here's the information in the picture.
