Part of the fun of geology is making visits to sites of interest, where the geology, industrial archaeology, or both can be seen in-the-flesh as it were.

To help people get the most out of such visits TVRIGS has compiled a number of outings (geotrails) for visitors to download and help with getting into the countryside, walking and experiencing for themselves some of the district’s geological wonders.

IMPORTANT: Please see safety note at the foot of this page before going on any of the outings.

Safety on visits to geological sites shown in these documents remains entirely the responsibility of the visitor(s). Sites may include high, unfenced drops – such as sea-cliffs and quarry faces – so please remain aware at all times.

Dogs should be kept on a lead.

Follow the Countryside code, Take your litter home with you and respect the countryside.

When visiting the foreshore (for example below sea-cliffs near Hummersea) do not depart during strong northerly or easterly winds as tides fall more slowly and rise more quickly.

Check the tide times here beforehand, and begin your visit no later than 2 hours before low water.

Whilst on the scar remain aware of the time of day and state of the tide at all times.

Approach no closer than 10m to the foot of the cliff and wear a safety helmet.

Let someone know where you are going and what time you expect to return.

Disclaimer: Tees Valley RIGS Group cannot be held responsible for accident or injury suffered during visits to localities shown on these web pages.
