Although yellow fever does not occur in Costa Rica, an official yellow fever vaccination certificate may be required depending on your itinerary.
- Requirement: A vaccination certificate is required for travelers aged ≥ 9 months coming from countries with risk of YF transmission (except Argentina and Panama). Note: This does not apply to airport transit stops (no exit through immigration checkpoint) in risk countries.
Depending on your itinerary, your personal risk factors, and the length of your visit, your health care provider may offer you vaccination against hepatitis A, hepatitis B, influenza, measles, mumps, rubella, rabies, or typhoid fever. Routine immunizations, such as those that prevent tetanus/diphtheria or "childhood" diseases, should be reviewed and updated as needed.

No intrinsic risk of attack by terrorist groups exists, but unforeseen attacks are possible.
High risk of violent crime (armed robbery, sexual assault, carjacking, and murder) and petty crime exists throughout the country, especially in coastal areas of Limón Province (from Tortuguero to Puerto Viejo), Puntarenas Province (particularly in Malpais, Montezuma, and from Puntarenas to Dominical), and Guanacaste Province (particularly in Tamarindo); on main highways in Central Valley region; and in San José. Theft of valuables from unattended rental vehicles is common.
Express kidnappings to force cash withdrawals at ATMs may occur throughout the country.
Scams involving the use of distraction techniques to commit robbery (including puncturing tires and posing as a helpful passerby) have been reported.
Protests and demonstrations occur and have the potential to turn violent without warning. Bystanders are at risk of harm from violence or from the response by authorities.
Hazardous water conditions (including currents, tides, and undertows) may occur along the Pacific and Caribbean coasts. Heed posted warnings, and avoid beaches that are not patrolled. Do not swim alone or after dark, and do not walk on any beach after dark.
Passenger boats may be unsafe, including small crafts. Decline water transportation in vessels that appear overloaded or lack personal flotation devices or life jackets.
Basic safety standards for recreational water activities (including scuba diving and rafting) are often not in place. Rent water sports equipment from reputable operators. Scuba dive only with personnel certified by PADI or NAUI, and use equipment only from PADI- or NAUI-certified dive operators.

Travelers should closely follow regulations from local authorities and always maintain a safe distance from wildlife.
High risk of traffic-related injury or death exists. The road-traffic death rate is 12 to 24 per 100,000 population. The rate is less than 10 in most high-income countries. Seek local advice before traveling on roads outside urban areas after dark. Driving at night is not advised.
Traffic flows on the right-hand side of the road. Travelers (including drivers and pedestrians) accustomed to traffic moving on the opposite side should be vigilant when navigating traffic.
Many taxis are unsafe. Use taxis from official ranks or dispatched via smart phone app or radio from a reputable company and ascertain the license or identification number of the dispatched vehicle.
