Two large, high areas like this, plus a space for the Lar gibbons that is inaccessible to the orangs. Offshow rooms are at the back and also offshow in this photo.
@Gigit Despite its simplicity compared to e.g..'Islands' at Chester, I would still rate this as the best(?) indoor accomodation for Orangs within the British Isles(or whatever technical description includes Jersey!)
@Pertinax Having recently seen them all, I agree. They use all the space and particularly seem to enjoy those 'nests'. The exits to the bridges are high up so they have to climb to get to them.
