Security in Palawan is at a fairly high level. The locals are characterized by good-naturedness and harmlessness. However, even in this paradisiacal corner of the globe, you should not let your guard down, as pickpocketing in public places is a common occurrence.
Don't forget to take precautions on the beaches. It is ideal in Palawan to swim and walk on the beach in crocs, as there may be poisonous sea urchins or sharp barnacles in the water.
