Guatemala has active volcanoes, some prone to heightened activity. Before climbing any of the volcanoes, you should check and follow the advice of local authorities and monitor the situation. Local authorities have taken extra security measures due to the increased activity of Fuego volcano.
Guatemala has one of the highest violent crime rates in Latin America. Take care in all parts of the country, including Guatemala City. You should carry personal ID when travelling (certified copies are fine).
Avoid travelling on public buses (repainted US school buses). Private inter-city coach services are safer, but not immune from attack. See Local travel.
Large demonstrations occur throughout Guatemala, often with little or no notice. There may be disruptions to traffic and public transport. You should avoid all demonstrations. See Political situation.
Remember to take out comprehensive travel and medical insurance before you travel.
