Rotorua, New Zealand - This city on the North Island of New Zealand is incredibly smelly due to high levels of geothermal activity.

Seal Island, South Africa - They play, chatter, and do their business on the rocks around the island, making it a very smelly place.

La Brea Tar Pits, Los Angeles - The tar pits are located along LA’s miracle mile and offer visitors the opportunity to take a trip to the prehistoric past.
