Colombian municipality of the department of Norte de Santander
Pamplona is a small city in Norte de Santander, Eastern Andino, near the Colombian border with Venezuela.
Pamplona is a college town with many museums and bars and a cool climate. It is a common stopover on the way to Venezuela to avoid the heat and chaos of Cúcuta, however it's a solid 2 hours from Cúcuta so you'll have to leave early if you want to cross the border early the same day.
Regular bus service from Bucaramanga and Cúcuta.
There are lots of cheap eats along Calle Real. If you like empanadas, pizza and generally greasy food, you'll do fine here.
There is a vegetable market a block up from the main square.
There are several hotels in the COP$10,000-15,000 range along Calle 9.
Internet cafes are plentiful, but wifi is scarce. Like many places in Colombia, most coffeeshops and restaurants will advertise Wi-Fi and then claim it's not working after you've already ordered and paid. There appear to be a couple cafes with wifi on Calle Real, though they have strange hours.
