How to get to Samburu, Buffalo Springs and Shaba

The tarmac goes further than you have been told

Samburu has a reputation as a hard drive. The road itself does not deserve it. The whole route runs on the A2, which the Kenya National Highways Authority lists as the Great North Road Connection Thika, Kenol, Makutano, Sagana, Marua, Nanyuki, Lewa, Isiolo, Moyale. In practice you leave Nairobi on the Thika Superhighway and pass Thika, Kenol and Makutano, Sagana, Karatina, Marua, Nanyuki, Timau, Isiolo and Archer's Post. At Marua the Nyeri turning branches off, so anyone routed that way leaves the A2 for a stretch. The A2 is Kenya's leg of the Great North Road, the Cape Town to Cairo Trans-African Highway.

The northern section from Isiolo to Moyale is 504 km long, runs through Isiolo, Archer's Post, Merille, Marsabit, Turbi and Moyale, and is surfaced for its full length. The project was designated in 2008, cost 420 million dollars with funding from the African Development Bank, the Kenyan government and China Exim Bank, was built by China Wu Yi as main contractor, and was inaugurated by President Kenyatta in 2017. Wikipedia's article on the A2 dates the completion of the northern section to 2016 and its article on the Isiolo to Moyale road to the 2017 inauguration; both years are on the record.

So the tarmac does not run out on you somewhere in the middle of the day. It runs out at the turning. The A2 carries straight on towards Marsabit, and the side roads that leave it for the reserve gates are graded murram and gravel. For Shaba the main roads are surfaced and well maintained as far as Archer's Post, with the last stretches to the gate on gravel or sand and a turning that is often unsigned. The approach to Buffalo Springs is described as a well-maintained murram road. The exact kilometre point where tarmac becomes murram differs by gate and we could not confirm it for any of them.

Three things to expect on the way. KeNHA closed the A2 between Isiolo and Kirish from 17 April to 15 May 2026, between km 29+140 and km 29+300 near the access road to the School of Military Engineering, to reconstruct a failed section of pavement. That closure is over, and it tells you the surface on that stretch has been failing. On 8 February 2026 KeNHA announced a 147 km dual carriageway between Marua, Nanyuki and Isiolo, funded from the infrastructure fund, with no contractor or timeline made public. That is precisely your road, so plan for roadworks. And the 305 km Kenol to Isiolo highway, the existing single carriageway underneath all of this, is described as being in various stages of disrepair, with a duplication planned since 2019 whose original 2023 completion date passed.

One correction for anyone route-planning from a third-party page: some sources give this route as the A104, B3 and C12. The A104 is the Nairobi, Naivasha and Nakuru axis. Every other source we read gives the A2 consistently, and the A2 is what the signs say.

Distances and times, and why the numbers disagree

The published spread runs from 300 to 355 km. Most of it is explained by three things. First, the endpoint: Samburu's Archer's Gate, Buffalo Springs' Ngare Mara Gate and Kalama Gate are all different destinations, and samburureserve.com is the only source honest enough to say its figure moves with the gate you pick. Second, rounding of the same measurement: Wikipedia's 350 km and mistersafari's 355 km are both 220 miles converted, and 220 miles is 354 km, so those two apparent extremes are one number rounded twice. Third, one genuine outlier: safariasap's 300 km sits with its 4.5 hour drive time, and both are too optimistic to use. The band worth planning against is 320 to 350 km.

Six to seven hours is the realistic figure, and it is the one the two most specific sources give, the Saruni Samburu road directions and valleysafaris. Treat samburureserve's 5.5 to 6 hours as a best case on an empty road. No source we found puts a number on how much the Thika corridor morning rush adds, which is exactly why leaving Nairobi early is worth more than driving fast later.

The two hard sub-distances are useful for the last hour. Isiolo to Archer's Post is 34 km, and Archer's Post to the reserve gate is put at about 13 km.

The gates, and which reserve each one serves

Two corrections are worth carrying with you, because both circulate widely. Ngare Mara Gate belongs to Buffalo Springs and is run by Isiolo County Council, and almost every independent source places it there, so listing it as a Samburu gate sends you to the wrong county's ticket desk. And there is no Ngwesi Gate at Buffalo Springs. Il Ngwesi is a separate community conservancy in Laikipia. If a page offers you a Ngwesi Gate, treat everything else on that page with the same suspicion.

All gates open at 06:00 and close at 18:00, confirmed by several independent sources. Outside those hours you need the warden's permission, which is meant for breakdowns and bad weather rather than late starts. With a six to seven hour drive and a hard 18:00 close, an early Nairobi departure is the whole plan.

On payment, the accounts conflict and we will not pick a winner. The county Finance Acts say only that you pay the county through an authorised channel, and the Isiolo County Finance Bill 2023 adds that an official receipt must be issued for every payment and that you should demand it. Neither document mentions eCitizen, M-Pesa, card machines or a ban on cash, and the travel-trade accounts run all the way from cash in dollars or shillings plus Visa, Mastercard and M-Pesa at the gate, to nothing accepted except electronic payment. What is solid: you are paying a county, you are entitled to an official receipt, and a Kenya Wildlife Service ticket or annual card does nothing at these three reserves. Carry a fallback.

Whether one ticket covers more than one reserve is genuinely unresolved, and it decides whether you pay once or twice. Our entry fees page sets out the three competing positions and the wording in the Acts themselves.

One more open question that affects a day's driving. The bridge over the Ewaso Ng'iro between Samburu and Buffalo Springs was destroyed by the March 2010 flood, rebuilt by the British Army between September and mid-November 2010 and reopened on 25 November 2010, partly washed out again in 2011, which forced a 45 km detour, and repaired and reopened in February 2015. Expert Africa describes visiting the Buffalo Springs side within a game drive by using the reopened bridge near the reserve headquarters, and valleysafaris reports a bridge near Archer's Post linking the two. Kenyasafari.com still says the bridge is washed out and that you must detour via Archer's Post and Kalama, which reads like the 2011 to 2015 situation left standing on a live page. No source after 2015 reports a fresh washout, so the bridge is very probably open, and we found no official confirmation of that for 2025 or 2026. Ask your lodge before you plan a crossing into your day.

Do you need a 4x4?

• Yes for all three reserves, and with high clearance. Expert Africa describes game drives following sandy tracks along riverbanks and dry bushland, which needs a standard 4x4 safari vehicle for the uneven ground, and for Shaba recommends 4WD all year and emphatically in the rains.
• The tracks are graded and sandy, and after rain the routes through the luggas turn into running water. The County Government of Samburu describes its own internal road network as in good to decent condition, with washboard corrugation on the main routes.
• In the dry season a high-clearance 2WD will very probably reach the gate and cope with the main tracks. Inside the reserve, in the sandy luggas and after any shower, you want the 4x4.
• One dissenting source exists and is worth knowing about: a self-drive account from 20 December 2024 calls the roads dirt paths and very easy, without mentioning 4x4 at all. That is the only report implying you can manage without one, and only in the dry.
• Self-driving is allowed and no guide is required. At the gate you can optionally hire a ranger to help you find wildlife.
• Ignore one misleading line in circulation. 4x4africa.com writes that a self-drive safari to Samburu with 4x4 Africa is not allowed past Archer's Post. That is one company's hire policy, recognisable by the words with 4x4 Africa, and it is not a reserve rule. Several hire firms do set Archer's Post as the northernmost point their vehicles may go, so check your own rental agreement.

Safety: what the three advisories actually say

This is a page people make decisions on, so here are all three in full, with their dates, and no attempt to average them into a single verdict.

The Netherlands. Since 9 September 2026 the Dutch advice puts Samburu County and Isiolo County on yellow, the code for pay attention, there are risks. Both counties fall under the rest of Kenya, where yellow applies: travel is possible, with particular safety risks. The advice names the region directly. In translation from the Dutch: 'In the regions of Laikipia, Samburu, Turkana and West Pokot violent conflicts occur between herders and farmers. This also applies to the neighbouring areas of Baringo and the nature parks in the Laikipia region. Do you want to visit these areas? Ask what the latest developments are and what the security situation is. Preferably travel by plane. Do you have to go by road? Then travel with several people or with a local guide.' That text was last changed on 9 September 2026 and was still current when we checked on 18 September 2026. Separately, the Marsabit region is on orange, essential travel only; the A2 continues from Archer's Post towards Marsabit, and Samburu, Buffalo Springs and Shaba lie well south of it, entirely inside yellow. Mandera, Wajir and Garissa, mainland Lamu and Kiwayu island are on red. At yellow, Dutch insurers leave travel policy terms alone; at orange and red many of them change them.

The United Kingdom. The FCDO has no advisory against travel to Samburu County or Isiolo County. Both appear once, in Regional risks, in a list of counties: 'Turkana, West Pokot, Elgeyo-Marakwet, Baringo, Samburu, Laikipia, Meru and Isiolo counties. Security operations continue in parts of these counties due to banditry, cattle rustling and intercommunal violence. While previous dusk-to-dawn curfews have largely been lifted, movement restrictions may still be introduced during security operations, particularly in hotspots such as the Turkana-West Pokot border, Kerio Valley (Elgeyo-Marakwet) and remote areas of Samburu, and Baringo. Follow local security measures and use caution.' Samburu National Reserve, Buffalo Springs, Shaba and Archer's Post are named nowhere in the FCDO advice. The only phrase that touches this county is 'remote areas of Samburu', which refers to remote parts of the county. The FCDO does advise against all travel to Mandera County, parts of Wajir and Garissa counties and Lamu County away from Lamu and Manda islands, and against all but essential travel to Garissa Town, Tana River County north of the Tana as far as Saka, and within 15 km of the east coast between the Tana and the Galana. All of those lie several hundred kilometres east of this route. The page showed no visible last-updated date in the version we retrieved; we read it on 18 September 2026.

The United States. The State Department has Kenya as a whole at Level 2, Exercise Increased Caution, for crime, kidnapping, terrorism, unrest, health and traffic safety. It was reissued on 28 July 2026 with no change to the level; the other risk indicator was added and the summary updated, and the US embassy in Kenya published it on 30 July 2026. Samburu County and Isiolo County are not mentioned anywhere in the advisory, so the countrywide Level 2 is what applies to the destination itself. The Level 4 Do Not Travel areas are the Nairobi neighbourhoods of Eastleigh and Kibera, for crime and kidnapping; Garissa, Wajir, Mandera, Lamu and Tana River counties, with Tsavo National Park excepted, Kilifi north of highway C103 and the coast north of Malindi, for kidnapping and terrorism; West Pokot County and western Turkana County, for crime, where the advisory says 'Armed bandits are active in these areas'; and Marsabit and Turkana counties within 30 miles (50 kilometres) of the Ethiopian border, for unrest, which 'are prone to cross-border incursions from Ethiopia'. No point on the Nairobi, Nanyuki, Isiolo, Archer's Post and Samburu route falls inside a Level 4 area; the nearest is that 50 km strip along the Ethiopian border, hundreds of kilometres north of Archer's Post. The same advisory warns that protesters have attacked vehicles carrying Americans, including safari vehicles, and that road accidents involving safari vehicles are among the leading causes of injury and death among Americans in Kenya, with violent protests most common in Nairobi and western Kenya.

Read all three before you choose. None of them advises against Samburu itself, and all three name the wider region in connection with banditry, cattle rustling and intercommunal violence. The one place they clearly part company is Marsabit: the Netherlands puts the whole region on orange, while the United States restricts Level 4 to the 50 km strip along the Ethiopian border. That difference leaves the route to Samburu untouched and matters if you carry on north towards Marsabit or Moyale. The Dutch advice is the only one of the three that tells you how to arrive, and its preference is the aeroplane; our flights page sets out what that costs and what it gets you. Kenya is also running extra health checks on arrival because of an Ebola outbreak in neighbouring countries.
