In addition to El Nido, I was recommended by people I met on the trip to visit the island of Coron. The island is not far from El Nido and the only way to get there is by ferry. The express ferry from El Nido took 3 hours and it was a comfortable journey even though it got a little chilly due to air conditioning in the boat.
My first impression of Coron after arriving, was great. It seems like coming to a completely different world where life goes a little bit slower. In general, things felt much calmer here. The people also seem to be very nice and kind!
