2024 Branch Events

Field trips are open to all, with a small fee of £2 payable by non-members. Annual membership is only £5 for an individual and represents excellent value, so either join in advance or print off a membership form and join on the day.

Please note:
Remember to bring a packed lunch, stout footwear, and waterproof clothing.

You may be at risk from Lyme Disease when you visit the countryside. Lyme Disease is a relatively uncommon infection in the UK but it has recently started to occur more frequently. It is caused by a bacterium carried by ticks. People who walk in the countryside, especially those walking through grass, rough vegetation, or wild areas such as heathland, are more at risk.
For more information visit the Lyme Disease Action website.

Check the website for the latest status and updates on planned field trips.

Young persons under the age of 18 are welcome to attend all meetings. However, as the Yorkshire Branch of the BDS has no member registered under the Children’s Act, their parent or guardian must accompany them. The leader of an event should also be consulted in advance if children wish to attend.
