Here is a nice set of pictures of Chulillia and why it is something special. There is hiking, fishing, spectacular views, an old castle with a great history, and they have a barrio called Santa Barbara so you cannot go wrong. Amazing gorges and hiking is right there as well as some first class fishing. On some days you can find rappels scaling the steep walls. There is an amazing castle overlooking the town and was once the main fortress. The views from, what the locals call, suicide window, is amazing as it overlooks the whole river gorge. I have hiked into the hills many times and enjoyed picking berries along the way and sharing tales with the fishermen taking their catch out of the fast flowing river.
