Kenya
You need to pay the entrance fee for the Aberdare Park here at the headquarter. It’s not possible to pay at the treetops gate. It’s 60USD for non-residents. If you don’t camp inside the park (which is another 20USD ppn) the fee is only valid for the rest of the day. So if you arrive at lunchtime you need to pay still 60USD.
Why? By checking in after you’ve visited a place you let others know this place is still functional. You can also add or correct any information.
Headquarters for Aberdares. This is where you book your campsites.
