This is only place in the Philippines where you can find a desert in the seemingly endless coastal sand dunes of Suba. It is about an hour's walk along the beach from Fort Ilocandia. It is quite an exercise and walking in these sand dunes feels like meditating. The sky feels a little bit closer. It is a an awesome place for reflection. I suggest that you walk during early morning and ensure that it won't rain.
