We visited a few years ago but it was blazing hot with high humidity :-( Despite that, we were very impressed and always planned to return at a future point when the weather was more agreeable! The animals were well-cared for, the staff was friendly and knowledgeable and the trails/exhibits were wonderful. We couldn't even explore it all because it was too hot for us! So happy to say that we are vacationing in NH next week and cannot wait to return as the weather looks more reasonable for outdoor adventures!
