Southern Water's famous sewer tours have been revealing their Victorian secrets to visitors for more than 50 years.

The award-winning tours run from May until September and are a popular attraction with visitors from across the world.

Tour guides will take you through 400 yards of the 30 miles of sewers, starting at the Palace Pier and emerging through a manhole in the middle of Old Steine Gardens.

All visits must be pre-booked. Find out more about booking a place on one of the tours.
