Mandritsa and Odrintsi are almost abandoned villages that are like an open air museum – it is wonderful to walk through the sandy streets and watch the houses and people in the gardens.
On Wednesday morning a market with fresh fruits and vegetables and some other stuff like clothes is located in the centre of Ivaylovgrad.
For a nice overview of the city you can walk uphill to Dupkata area, which is also a good place for orchids.
