10km Tre Cime circuit track that starts and finishes at Rifugio Auronzo.

Because the carpark at Auronzo was full already by the time we got there, the road was blocked off at the bottom carpark. From there we chose to walk up instead of taking the bus, which added 5km each way.

So we ended up walking 21km, took 7 hours overall including the breaks. Big day!
