Colombia

Colombia's mountainous terrain makes domestic flying the fastest and often cheapest way to cover long distances -- Avianca and several budget carriers connect Bogotá with every major city, and flying is standard even for trips that look short on a map, since Andean roads wind through mountain passes rather than running direct.

Long-distance buses are extensive and comfortable on major routes, but genuinely slow given the terrain -- a bus ride that covers 300km by road can easily take 8-10 hours. Within cities, Bogotá's TransMilenio bus rapid transit system and app-based rideshares are the standard way to get around.

Getting to smaller colonial towns like Barichara usually means a shared van or private transfer from the nearest larger city rather than public transit directly.

Colombia's safety has improved dramatically since the 2016 peace agreement, and the country's major tourist circuits -- Bogotá, Cartagena, the Coffee Region, and Santander's colonial towns -- are visited by millions of travelers each year without incident. That said, real regional variation still exists, and a few practical precautions go further here than in many other South American destinations.

• "Paseo millonario" (millionaire's ride) -- a scheme where a fake or complicit taxi driver forces a victim to withdraw cash from multiple ATMs -- is a real, if now less common, risk in Bogotá; use app-based taxis (or a hotel-arranged car) rather than hailing one on the street, especially at night.
• 
  
• Scopolamine ("burundanga"), a drug sometimes slipped into drinks or offered on a soaked piece of paper, can incapacitate a victim -- never accept drinks, cigarettes, or paper from strangers, a rare but genuinely serious risk unique to Colombia and a few neighboring countries.
• 
  
• Rural and border areas, particularly parts of the country near the Venezuelan and Ecuadorian borders and some remote jungle regions, can still see armed-group activity or drug-trafficking-related risk well off the standard tourist circuit -- check current government travel advisories before venturing beyond well-established routes.
• 
  
• Petty theft and pickpocketing follow the same pattern as most major Latin American cities -- keep valuables out of sight on public transport and in crowded areas of Bogotá and Cartagena's Old Town.
• 
  
• Altitude is a real, non-criminal consideration -- Bogotá sits at roughly 2,640 meters (8,660 feet), high enough that some visitors feel genuine altitude effects (headaches, breathlessness) for the first day or two.
• 
  
• Emergency number: 123 works nationwide and connects to police, fire, or medical services.
