my mate mario and i just travelled through colombia last week. we took the following route: quito - pasto - cali - ibagué - bogotá - bucaramanga - cúcuta - venezuela.
although the people, the landscape and the roads are simply awesome, the situation is NOT. during our time there another 30 people were kidnapped on the panamericana, an ex-minister afterwards executed.
the head of security of unicef colombia said he would have forbidden us to travel through his country if we had been employed by them instead of being volunteers.
if you decide to do the trip regardless, start travelling at 6am or earlier and be off the road by 4pm. keep a low profile and do not leave the main roads.
if you need any more specifics, just mail me!
