Living in Puerto galera means: traveling to Batangas every now and then. With the bankas leaving from Muelle there is a good connection to Luzon Island and Batangas is the gateway to Manila as well. Hop on a bus and within 3 hours you enter the metropolis. Batangas offers just a little more than Calapan on Mindoro does. SM Mall for example, with a lot more variety on shops.
But also the city center is fun to roam around. I took a walk through the public market. It is a large combination of wet and dry market and a big food court that draws you in with it delicious smells.
Public markets are the best places to buy things, they are well stocked, cheap and you find them everywhere in the Philippines
