There are three gates to the reserve, all of them accessible from by-roads off the B4 main road leading to Baringo. The main gate is Loboi Gate, at the lake's north end. The detour eastward from the B4 is 4 km south of Marigat. A paved road, the E461, heads for Loboi and the gate after a 21 km stretch.

The two remaining gates are southward, taking the east turn off B4 at Mogotio, 59 km south of Marigat. This road covers some 20 km up to Mugurin. One kilometer ahead, the road splits into two. The left track heads on for some 20 km until a right turn-off which leads you to Maji Moto Gate, close to the hot springs. On the other hand, the track at the right, badly damaged and quite steep at some stretches, covers 14 km before reaching Emsos Gate, the southernmost gate, at the reserve's forest area.

Finally, there is also a scenic route to reach Emsos Gate from Nakuru, climbing from the Rift Valley bed up the eastern escarpment to drop back down again to Bogoria. A good part of this way is only accessible to 4WD vehicles. Leaving Nakuru along the A104 to Nairobi, take the tarred B5 road northeastward to Nyahururu. Along the way there are several detours heading northward for Bogoria, taking as reference points the towns of Subukia and Solai. If you are not self-driving, you can take a bus or matatu for the paved stretch, but afterwards you will have to walk for some two days.
