Northern Kenya is a beautiful and thoroughly under-rated area.  Whether after the rains, in June or July when it is lush and bursting with life, or at the end of the dry season in October, it has its only particular brand of beauty.  July – August can be pretty cold, so the woolly boots that are made on Borana Ranch come in handy.  December – March are the warmest months and usually the driest.  The scenery is always lovely, and this is a place you visit for more than just the wildlife, however if you are keen to see game, then July – October and January – March are probably the best times.
