A difficult hike but worth all the effort needed to get up to Tre Calli. The journey up is not too bad asides from getting to the trailhead from Bomerano, and the last ascent to the summit. The views from Tre Calli are absolutely phenomenal. If you continue onwards to Capo Muro it’s about another 20-25 minutes. From there you can continue to the third summit Catello. We did not do the third summit as it was hot, we didn’t have the time and that is also the most difficult part as it’s a very steep uphill ascent.
