Silvia is a 1 hour bus ride (curvy roads) from Popayan. It features an authentic market full of locals and very few tourists. Clothing, electronics, houseware, freshly butchered meat, fruits, etc. are sold there. At the market one can find Guanbano Indians dressed in their traditional outfits unpacking wares from traditional chiva buses.
Silvia also has a nice plaza with many churches throughout the town. Even on the busiest market day one can easily escape to find calmness. Hiking up to the church on the hill offers a spectacular view.
There is one ATM in town, for non-Colombian cards there is a charge of ~COP10,000/transaction this is in addition to what your home country bank may charge.
