Mt Longonot National Park in Naivasha, Nakuru County has been closed due to concerns of poor sanitation.
There have been an acute water shortage, said a report from public health officials.
In a notice, Mai Mahiu Public health officer George Mwangi, said the national park should stop receiving visitors until issues of water and sanitation are attended to.
"The department has noticed you are causing a nuisance by failing to provide sanitation to the satisfaction of the public health act," part of the notice read.
The notice disclosed that the Kenya Wildlife Service (KWS) has failed to provide water for public toilets. It also revealed that the only pit latrine in the park is currently filled up.
"You are required, with immediate effect, to provide water in the toilets, keep them clean and cease from using the already filled up latrine," the notice read.
"This is very shameful especially because the park makes a lot of money each day. The blame lies squarely with KWS headquarters who are very eager to receive collection from the park but fail to pay suppliers," a worker who declined to be named told a local paper.
KWS spokesman Paul Gathitu said he will issue a statement on the matter after consultations.
