Significant safety concerns; travel only if you have a clear reason to go. Political freedoms are limited and travellers should be mindful of local sensitivities.
Regional breakdown
The picture in Kenya changes sharply by region. Nairobi, Mombasa, the Rift Valley, and the main safari parks like Maasai Mara, Amboseli, and Tsavo sit outside the strictest warnings. Most visits cluster here. The official advisories both treat these areas as standard caution rather than no-go zones. The northeast is the hardest line. The official advisory guidance warns against all travel to Mandera County, most of Garissa County, parts of Wajir County, and most of Lamu County. The trigger is spillover from armed groups based in Somalia. Lamu Island and Manda Island are carved out of that warning, so the historic old town remains reachable by air. Garissa Town and a strip of Tana River County north to Saka sit one step down, with official advisory guidance warning against all but essential travel. The official advisory guidance flags a wider net at its top Level 4. That covers the Somalia border counties, Kilifi north of Malindi, parts of West Pokot and Turkana. And a 30-mile band along the Ethiopian border in Marsabit and Turkana. Washington also tags the Nairobi neighbourhoods of Eastleigh and Kibera at Level 3, citing crime rather than terrorism.
Recent advisory changes
The official advisory guidance last updated its Kenya page on 27 March 2026. The refresh added a note about an ongoing security operation in Laikipia, Meru, and Isiolo counties. The core map of no-go zones along the Somalia border and the Lamu mainland did not change. The official advisory guidance still leans on the same terrorism rationale it has used for several years. And reminds travellers that ignoring the advice can void travel insurance. The official advisory guidance keeps Kenya at Level 2, Exercise Increased Caution, with the most recent reissue dated 17 March 2025. There is no ordered departure for US government staff and no evacuation guidance for private citizens. The official advisory guidance continues to single out armed carjacking, mugging, home invasion. And kidnapping as risks that can show up anywhere in the country, alongside the regional terrorism warnings. The two governments line up on the border zones but split on Nairobi: London treats the capital as standard caution. While Washington pulls out Eastleigh and Kibera for tighter warnings.
What travellers should know
Most trips to Kenya focus on Nairobi, the coast around Diani and Mombasa, and the safari circuit. None of those sit inside the top UK or US warning zones. The practical job is matching your route to the map. Anyone heading to Lamu should fly in rather than drive the coast road through Tana River. Trips to the far north or northeast need a hard look at both the official advisories pages first. And a check with a tour operator who works the area. Crime is the day-to-day issue rather than terrorism for most visitors. Both governments flag carjacking, phone snatching, and home break-ins. Watch out for ATM use after dark, walking with bags in Nairobi central business district, and matatu travel late at night. Road conditions and driver behaviour cause more harm to tourists than political risk. Travel insurance that covers Kenya is worth checking line by line, since UK policies often exclude trips taken against official advisory guidance advice. Register with your embassy if you plan to visit the border counties, and keep a copy of your passport separate from the original.
