We were warned that the car park would be full by around 8.30am, so we left Cortina just after 6am, got to the carpark at 6.45am and at that time there were 120 car places left according to the sign next to the booth where you pay the 30 Euro parking fee. Best to be prepared with which trail you want to do and how long you want to walk, as there are many options. Most of the trails are not marked with the usual wooden signs, so best to take a map or have a navigational device that doesn't rely on 5G Cellular. We met a guy who went 4 kms out of his way, as he missed the turn. We did the classic Tre Cime, 10 km loop which took just under 4 hours, with a long break for coffee and cake at Langalm Chalet, which is about 2/3 of the way around the loop. Track is good in parts, but lots of rocks, loose stones and on 29th June there was still a lot of snow next to the track so muddy in places. The trail is exposed, there's a long uphill steep climb at about the 90 minute mark. Bring plenty of water & snacks and wear layers, it was 14C to start but soon warmed up to 22C. When we got back to the carpark around 10.30am there was a queue of cars waiting to get in.

VERY BUSY as expected in July. We arrived just before 8am and had to wait around 30 minutes at the toll gate, €30. BUT it was so worth it. We did the easy route. 10km, which took around 4 hours with a few stops for water and snacks. There were busy parts along the way, although most of the path was fairly quiet. There are much quieter walks in the park if you don’t want to do the standard Tre Cime loop.

Beautiful scenery of the drei zinnen / tre cime. The road to the top is great and the tre cime itself also. The trail is well maintained, but overcrowded. My advise is to depart as early as possible to start the hike before the crowd comes. We spend to night at the top in our RV, so we were there before the crowd. In our case we went up at 16:00h and had nu issue at all.
