Ulu Camii, then Koza Han and the covered bazaar; İskender for lunch and tea in the Koza Han courtyard.
Day 2
Green Bursa
The Green Mosque and Green Tomb, the Museum of Turkish and Islamic Arts, Emir Sultan Mosque and Irgandı Bridge.
Day 3
Up the mountain
The gondola to Uludağ: snow play at Sarıalan or a first ski lesson in the hotels zone. Stay the night if you can.
Day 4
Snow day
A full day on the slopes, or sledging and snowmen for small children; back to the city in time for dinner.
Day 5
Village and springs
Cumalıkızık in the morning, the Muradiye tombs after lunch and a thermal bath in Çekirge.
Honest thought: Uludağ’s snow and weather change quickly. Check the gondola status and the snow before you go up, keep one flexible day, and avoid the busiest weekends if you can.
