All nationalities need visas before entering Eritrea which can be obtained in advance through various Eritrean Embassies or online. Tourist visas are valid for up to three months and overstaying your welcome is a serious offense, so make sure you have everything about your trip planned to avoid unnecessary delays. There are several types of visas available, including tourist visas, transit visas and same-day express service visas. Travel permits need to be obtained when traveling outside of Asmara so take the time to investigate before you plan a trip.
Health and Safety
Vaccinations are not required for travel to Eritrea, but strongly advised, especially for those who are at high risk of rabies and hepatitis A and B. Take precautions against Rift Valley and Dengue fever as well as meingococcal meningitis. Comprehensive medical and travel insurance is recommended. Note that healthcare facilities are very limited throughout the country, and even more so in rural areas. Modern clinics and health centers can be found in major cities and larger towns, along with chemists and hospitals that deal with emergencies.
It may take you some time to get used to the low oxygen levels at high altitude areas. Should you have any heart ailments or be suffering from high blood pressure related conditions, talk to your doctor before traveling to Eritrea.
Minor annoyances like children who aggressively ask for money will usually leave you alone if you act stern. The streets are safe even at night. Crimes, even petty ones, are not prevalent. You should, however, be careful when crossing streets as bike and road accidents are common. It is also important to check travel restrictions and safety warnings before and during your trip to Eritrea.
