From Cortina d'Ampezzo, I recommend going to Ortizei and staying there for another 3-4 days.
Ortizei is a beautiful little picturesque town encompassed by gorgeous mountainscape and lush green pastures. No doubt, it's a hiker's paradise.
In Ortizei, check in a hotel, where you'll spend your next 3 to 4 nights, while during the day, explore the following places around the town, such as Passes Pordoi, Sella, Gardena, Seceda, and pea-green valley of Alpe di Siuisi. In Alpe di Siuisi, which can be reached by a state-of-the-art lift right from the town, you may want to stay overnight to shoot both sunrise and sunset.
