    Excellent activity with excellent guidance from a very friendly Jorge.

    The caving was a highlight of our whole holiday. Jorge was able to perfectly accommodate all participants' levels. He kept patience and good mood all over the activity. We felt safe at all times, learned a lot and enjoyed Jorge's jokes.

    We will recommend him to anyone interested to do activities in the Valencia area and beyond.
