One of the best places this summer is Laiya in San Juan, Batangas. From Manila you can take the Star Tollway via Lipa or Rosario and try the local version of “lomi” and the small bread in town. Upon reaching the town of San Juan, visit its public market and buy some seafood of your choice.
From the public market, go straight to Brgy. Humabon (approximately 30 minutes away from the market) were the nice stretch of beach is located.
I stayed at Agudo beach resort near La Luz, a small resort. The place is simple and secured, water is clean, resort staff are very accommodating and people in the beach are friendly.
Most importantly the place is not crowded and lots of “sari-sari” store are conveniently located at the back of the resort , selling reasonably price goods.
