I always stay at Las Pocitas Mancora. I think it is the best, but others like the Mancora beach bungalows hotel. Its up to you. I live in Piura. It is close to Puerto Palos, and my family own the Arenas Mancora Hotel. That is why I have so much experience. Hotel Los Corales is OK, but i would go a bit further away and check out Punta Sal where they have the hotel sunset. Mancora hotels is the best site you could possible hope for. Make sure you tell all you friends about it and keep up to date.
