Mole is by fay the best place in Ghana to spot wildlife, especially the savannah elephants. Tours are available on short notice through the central visitor's centre.
Guides are very, very knowledgable and do their best to show as much animals as possible. But, it's a safari, so no guarantees!!
The park's lodge has a various range of rooms that differ in luxury, ranging from chalets with a small balcony and AC to (rather large) rooms with fans. We were in the latter and didn't miss the AC as you can ventilate the room really well trough the windows. However, we were staying in the relatively cool period in July/August.
You can easily fill three or four days here doing the different tours: by jeep, on foot, night-safari.
