Explore the Thames foreshore and discover what it's like to be a mudlark, in association with Thames Explorer Trust.

Join Thames Explorer Trust for a guided tour of the north foreshore by the Millennium Bridge as part of your visit to the Secrets of the Thames exhibition.

Their experienced guides will help you find and identify surface archaeological artefacts revealed by the Thames, uncovering thousands of years of history, like who lived there and how they lived.

Who knows what you'll discover. Smoking pipes, drainpipes, pottery, bones? There's lots of evidence of London's past to be found.

The meeting point is the glass obelisk located beneath the north side of the Millennium Bridge. For further details, please check our 'Need to know' section.

Please wear sensible footwear like wellies, old trainers or walking boots. No sandals, high heels or bare feet.

This event isn't safe for dogs, so it's important that you don't bring your dog to the foreshore, as you will not be allowed to participate.

Tours happen in a mixture of rain and shine, so don't assume that an event is cancelled because of a weather forecast.

In the event that Thames Explorer Trust is forced to cancel, you'll receive a full refund.

On a very few occasions, Thames Explorer Trust have been forced to cancel an event at the point of entering the foreshore. As a rough guide, these are the main weather conditions where we may need to contact you:

  • snow and ice, making the ground treacherous
  • heavy fog, which severely restricts visibility of the group by our staff
  • lightning
  • amber weather warnings
  • yellow weather warnings, as although tours still tend to go ahead, we may need to use a different foreshore

For more information, please see the Thames Explorer's FAQs and terms and conditions.

A Thames Explorer Tour guide will deliver an introductory talk at the meeting point which lasts 30-40 minutes. The meeting point is at the museum and staff will be able to direct you on the day. You should have plenty of time to meet your guide. In case of very late arrival, please talk to museum staff.

Please be aware that the foreshore may be exposed to waterbourne diseases. However, with the correct safety guidance, it's still a safe place to explore.

Please find more on health and safety on the Thames Explorer FAQ and terms and conditions.

Following the PLA’s regulations, if you don't have a permit you're not allowed to remove items from the foreshore.

Both permit holders and non-permit holders need to report objects of interest to the Portable Antiquities Scheme.
