Don't be fooled by the wooden turquoise cages; this humble-looking place is one of the world'smost renowned snake research centres. It specialises in antivenin research, and also acts as an emergency service for snake-bite victims throughout the region. Passionate guides lead excellent 45-minute tours (included in the price); they're highly recommended if you're heading into the bush and want to identify the most deadly serpents. Pricey snake safaris can also be organised.
