The Twinkling Tunnels
The idea of slowly riding through a dark tunnel is kind of creepy, but in New Zealand you can do so with the illuminating from tiny blue pinpricks of light overhead. These lights come from glowworms attached to the ceiling.
The Baobab Boulevard can be found on Madagascar, the isolated African island. The baobab trees are massive, thick trunked specimens that look like they come from fantasy worlds when stuck together.
