In the grounds of the National Museum, the Snake Park has some impressive snake species, including the puff adder, black mamba, Egyptian cobra, African rock python and Gaboon viper (with 4cm-long fangs, the longest in the world). There are also local fish species, lizards, turtles and some sad-looking crocodiles. Watch for the elephant fossil on the way down from the museum.
Note the Gaboon viper's venom description: 'A good-natured snake that rarely bites. However, a bite would be a major medical emergency'.
