We were really disappointed with Welchman Hall Gully. It takes about half an hour to wander through it, and unless you have a real interest in tropical trees, it is probably not going to be of much interest to you. We mainly went to see the monkeys, but as we were not there at feeding times, we only glimpsed a couple of them from a distance. We sad more monkeys in the grounds of our hotel than we did here. Would not recommend it.
