Most travelers who cross northern Kenya on the A2 highway never know they have driven through a national reserve. Losai National Reserve covers 1,806 square kilometers of volcanic hills and dry plains between Merille and Laisamis. It sits almost exactly halfway between Marsabit town and the Samburu circuit. The reserve has no lodge gate, no ticket booth on the highway, and almost no tourist traffic. For travelers who already know Samburu and want to see what sits beyond it, Losai is the missing link.
Touring Insights built this guide to cover where Losai sits, what lives there, and how to reach it. It also compares Losai to the two better-known protected areas around it. Every number below is a real distance, fee, or size, not a marketing estimate.
Where Losai National Reserve Sits Between Marsabit and Samburu
Losai was gazetted in 1976 in the Losai Mountains, immediately southwest of Marsabit National Reserve. The reserve straddles the modern boundary between Marsabit and Samburu counties. It sits roughly 175 km north of Mount Kenya as the crow flies. The A2 highway, Kenya’s main route to Ethiopia, cuts through Losai’s eastern section between the small trading centers of Merille and Laisamis.
That road frontage is deceptive. Drivers passing through see flat, scrubby ground close to the tarmac. The reserve’s interior sits further off, reached by turning toward the Losai Mountains themselves. It is a different landscape of rocky ridges, lava plains, and seasonal rivers lined with acacia woodland. There is no fence and no formal gate like Samburu’s Archers Post entrance. Access runs through Marsabit County’s local administration. Most visitors arrange entry through a guide based in Marsabit town or South Horr rather than showing up unannounced.
What Makes This an Off-Grid Wildlife Corridor
Losai connects two ecosystems that would otherwise be cut off from each other. Elephants and other wide-ranging species move between the Marsabit highlands and the Samburu-Isiolo lowlands, partly through this corridor. That movement peaks in dry years, when animals follow seasonal water. Conservation groups working in northern Kenya treat Losai as a linkage zone, not a standalone wildlife destination. That status is exactly why it stays off most safari itineraries.
That corridor role means sightings are less predictable than in a fenced, managed park. You are not touring a stocked wildlife theater here. Instead, you are visiting a working piece of a much larger ecosystem, where animals pass through rather than gather at a permanent water source. Guides who know the terrain read fresh tracks and recent local reports. There is no radio network of other vehicles to lean on, since there usually are none.
Wildlife You Can Actually See in Losai
Losai protects elephant, greater and lesser kudu, lion, gerenuk, and Grant’s gazelle. Smaller numbers of Grevy’s zebra and leopard also pass through. Black rhino were part of the original 1976 protection mandate. Sightings today are rare to nonexistent, though, and should not be promised to guests. Reptile life is notable too, with cobras and pythons recorded in the rocky sections.
Bird life is strong along the seasonal river woodlands, especially for travelers coming from the more open Samburu plains. The vegetation shifts from riverine acacia to bare volcanic rock over just a few kilometers in places. That shift concentrates species in narrow bands instead of spreading them across open country.
Getting There: Roads, Distances and Drive Times
There is no shortcut into Losai. The standard route runs from Nairobi north on the A2 through Isiolo and Archers Post, continues past Merille to Marsabit town, then backtracks into the reserve. A 4×4 with high clearance is not optional here. Two-wheel-drive vehicles cannot manage the interior tracks, even in dry weather.
| Route Segment | Distance | Typical Drive Time | Road Surface |
|---|---|---|---|
| Nairobi to Isiolo | ~273 km | 4-5 hours | Paved (A2) |
| Isiolo to Archers Post (Samburu gate area) | ~34 km | 30-45 min | Paved |
| Isiolo to Marsabit town | ~258 km | 4-5 hours | Paved (A2, upgraded 2013-2017) |
| Nairobi to Marsabit town | ~530-560 km | 7-8 hours | Paved (A2) |
| Marsabit town into Losai interior | ~50 km | 2-3 hours | Unpaved, rocky 4×4 track, dry season only |
Rains can close the interior track entirely, sometimes for days. Build a buffer day into any itinerary that includes Losai. Confirm current conditions with a Marsabit-based operator before committing a full day to the drive.
Losai vs Samburu vs Marsabit National Park
Travelers planning a northern Kenya route often ask how Losai stacks up against the two reserves it sits between. Samburu National Reserve is the established safari draw, with lodges, a defined gate, and predictable game viewing. Marsabit National Park protects the forested crater lakes around Mount Marsabit, including Lake Paradise. Losai has neither, and that gap is the point for the right traveler.
| Reserve | Size | Non-Resident Entry Fee (indicative) | Access | Infrastructure |
|---|---|---|---|---|
| Losai National Reserve | 1,806 km2 | Not centrally posted; confirm with Marsabit County office | 4×4 only, unpaved interior track | No lodges, no formal gate |
| Samburu National Reserve | 165 km2 | ~$85 per adult/24hr | Paved to Archers Post gate, murram inside | Multiple lodges and tented camps |
| Marsabit National Park | 1,554 km2 | ~$30 per adult (Lake Paradise access) | Paved A2 to Marsabit town, then park roads | KWS-managed, limited camping |
Losai is more than ten times the size of Samburu but carries a fraction of the visitor traffic and none of the fixed costs. Size and solitude against comfort and certainty: that trade-off is the entire pitch for a traveler who has already done a conventional Kenya circuit.
Best Time to Visit Losai National Reserve
The dry windows of June to October and January to February give the best chance of a passable interior track. Wildlife also concentrates near remaining water in those months. The long rains, typically March through May, and the shorter rains around November, can wash out the Marsabit-to-Losai track completely. Local road conditions change faster than any published safari calendar. A same-week check with a Marsabit contact matters more here than in better-maintained parks.
Where to Stay Near Losai
Losai has no lodges inside its boundary. Marsabit town sits about 50 km from the reserve’s accessible interior and has the most reliable guesthouses, plus a small selection of budget lodges. South Horr, closer to the Samburu side of the corridor, offers simpler accommodation aimed at travelers heading toward Lake Turkana. Neither option matches the tented camp standard of Samburu or the Mara. Travelers expecting that level of comfort should treat Losai as a day or overnight detour, not a multi-night base.
Explorer Notes
Ask your Marsabit-based guide for the current state of the 50 km interior track before you leave town. Locals get same-day updates from other drivers that never make it onto any website. A track rated “passable” on Monday can be impassable after a Tuesday storm in the hills.
Fuel up fully in Isiolo or Marsabit town. There are no fuel stations inside Losai or along most of the interior track, and the nearest reliable pump after Marsabit is a long way north toward Moyale.
Pack more water than you think you need. The rocky interior track can add hours to a trip that looks short on a map, and there is no shade infrastructure or rest stop once you leave the highway.
If Losai is a stop on a longer northern circuit, pair it with Marsabit National Park’s Lake Paradise crater lakes. Do not try to combine it with a full Samburu game-drive schedule on the same day. The driving alone makes that combination exhausting.

Frequently Asked Questions
Is Losai National Reserve open to the public? Yes, but there is no formal visitor center or ticket gate. Entry is typically arranged through a Marsabit-based guide or tour operator who handles county permissions.
Do I need a 4×4 to visit Losai? Yes. The interior track from Marsabit town is rocky and unpaved, and two-wheel-drive vehicles cannot manage it even in dry weather.
How far is Losai National Reserve from Samburu National Reserve? There is no single paved route connecting the two directly. Most travelers link them by returning to the A2 corridor through Isiolo, or by taking the rougher Baragoi-South Horr road on the western side. That western option adds significant drive time.
Can I see the Big Five in Losai? Not reliably. Elephant and lion are present, but black rhino sightings are effectively nonexistent today. There is no leopard or buffalo population comparable to Samburu or the Mara.
Is Losai safe to visit? The reserve itself carries no unusual safety concerns beyond standard remote-travel precautions. The bigger risk is logistical: getting stuck on an unmaintained track far from help. Travel with an experienced local guide and a second vehicle if possible.
