I very much enjoyed my stay at katia&dario' place. they are very helpful, with unbeatable response time. they gave me tons of useful hints; it's a pity that I didn't have enough time to explore all of them.
I went there mainly because I wanted to do the fiumara d'arte circle, which is indeed amazing, and definitely a must-see; it's like a treasure hunt and involves a lot of driving through the mountains; allow at best a full day. the only exception is 'stanza di barca d'oro', which was kind of annoying. after 7km off the main road one is informed that the cave has been sealed in 2000, supposed to remain closed for 100 years - it's called conceptual art. but all other stations are great, some even breathtaking, a few well positioned on mountain tops.
I also recommend to spend some time to explore the cosy centre nearby; there is a ceramic museum, and great outlooks.
