Hi Julie,
So far, I have managed to visit Chulumani, Irupavi, Chiqaloma and Coroico.
These are all in the Yungas region, which is much warmer and would be a nice getaway from the cold city, but at some point, you will have to pass through or near the World's Most Dangerous road.
It has beautiful scenery with countless waterfalls,and many tourist go biking along the road. The Yungas provide a good opportunity for adrenaline lovers and hikers.
