Yes. Animals are most active in the cool hours after sunrise, before the heat sets in and pushes many species into shade for the rest of the day, so an early arrival lines up with when there's the most to see. Leaving before dawn also means most of the drive happens before Nairobi traffic builds, which a private pickup can be timed around.
Yes. The route runs past the Great Rift Valley escarpment, with viewpoints over the valley floor, and through Narok, the last sizeable town before the reserve. Daytrip lets you build stops like these into the journey, so the hours on the road become part of the experience rather than dead time between two points.
The Maasai Mara National Reserve sits roughly 225-275 km (140-170 miles) southwest of Nairobi, depending on which gate you enter through. Plan on about 5.5 to 6.5 hours on the road, since the last 70-75 km (43-47 miles) before the reserve shifts from tarmac to a rougher gravel track. Traffic through Nairobi and conditions on that final stretch can add time either way, so it helps to build flexibility into your schedule.
It is a long day. With 11 to 13 hours of driving alone, going there and back in a single day leaves only a few hours for actual game viewing once you factor in park entry and rest stops. Most travelers get far more out of it by staying at least one night near the reserve. If a single day is all you have, a very early departure is the only way to make the math work, and a comfortable vehicle matters over a haul that long.
Few places pack in more wildlife. The reserve holds dense populations of lion, elephant, cheetah and the rest of the Big Five across open plains that make game viewing exceptional most of the year. Roughly July through October, it's also the stage for the Great Migration, when huge herds of wildebeest and zebra cross the Mara River. Visits to nearby Maasai communities add a cultural layer few other Kenyan destinations offer.
A drive this long is hard enough without a packed matatu or a shuttle making extra stops for other passengers. A private vehicle means your own pace, your own rest breaks, and enough room for luggage and camera gear if you're continuing on to a multi-day safari. You also control the return leg instead of waiting on someone else's departure time.
