if you ever end up in the north of portugal i highly recomend that you spend a night, especially if you re camping,in the area of gerez. other then the valley of douro, the national park was definetly the most picturesque places i visited. even though we got lost and it took us the whole day to get there by car i would have repeated the whole trip again. the wild horses, a bath in the cold water of the waterfall, and the friendly park guard who asked us nicely to pack up our tent from the picnic area.
