The Grumeti River flows West to East across the Serengeti National Park, before flowing into Lake Victoria; the Upper Grumeti refers to the section of the river that cuts across North Serengeti.
Two different types of woodlands can be found here: a lush gallery forest directly on the river banks while acacia woodlands flourish throughout the valleys and hills.
The lush habitat along the Grumeti River includes unique species, such as fig, mahogany, date palm and tamarind trees.
Opposite the gallery forest, large herds of hippos can be spotted bobbing and splashing in the dark waters that they leave at night  when they move to graze vegetation on the banks; while on the branches of the trees you can spot the Vervet monkey, large herds of baboons and, with a little more luck, you can spot the white and black colobus monkeys; although this wonderful species is more commonly seen along the Lower Grumeti River.
Fish eagles, turacos, kingfishers and many brightly coloured birds can be spotted on the treetops.
The acacia woodlands are covered with different acacia tree species, such as whistling thorn, paper-bark, green thorn and flood-plain acacia.
The hills and valleys to the North of the Grumeti river are carpeted with woodlands that provide shelter and food for many animals, especially giraffes who can be viewed here in large number; these wonderful herbivorous exclusively feed on tiny leaves of acacia trees and are able to eat it without getting stung with their thorns.
This area of the Serengeti is also home to elephants, topi antelopes, buffalos and large groups of impalas.
There is no lack of predators here, especially lions, leopards and cheetahs, while hyenas are not as widespread as in other areas of the Serengeti.
One of the best game drives in the Northern Serengeti is known as the Grumeti Game Loop; it is a U-shaped route diverging from the main road at Lobo and heading Northwest towards the Grumeti River and paralleling the Grumeti rivers for several kilometers before heading back Southeast to the main road at Lobo; it can take two hours to complete the game loop track, without considering possible stops.
In this area the Great Migration passes twice in the year: the first when it moves to the Northern grasslands in June and July, the second when it moves down towards the pastures of South Serengeti from September to November.
