Hertfordshire & Middlesex Branch
Saving butterflies, moths and our environment
Whether a member of Butterfly Conservation or not, you are welcome to join us at any of our free butterfly walks or moth events.
We have been reviewing our booking system again and some events will require advance booking through an online booking provider such as Eventbrite, although some walk leaders are happy to have no advance booking.
Sadly the Big City Butterfly Project has ended but we hope to include several walks in the project area this year
BUTTERFLY WALKS ARE FOR EVERYONE! You most emphatically do NOT have to be an expert to come on a butterfly walk. Butterfly walks can be enjoyed by anyone with any level of knowledge (or none). Photographers, children (with adult supervision), first-time participants, you are ALL welcome. Butterfly Conservation does not ask for any donation or payment to attend their walks; however some of the walks included in this programme when organised by another organisations may request a donation and/or a fee.
Neighbouring branches also have a wide-ranging programme of walks; some are quite close to our branch borders. The full list of Butterfly Conservation events can be viewed on the national website - here

Children
Children are welcome at our events, but if under 16 they must be accompanied by at least one adult for two children. It is the responsibility of the accompanying adult(s) to ensure that the event is within the children's ability.
Dogs
Dogs are normally welcome on walks but must be kept under control. Any exceptions are shown in the individual event details.
Bad weather
Leaders of Branch-led walks will be at the meeting point whatever the weather, but may cancel the event if conditions are unsuitable. Any exceptions are shown in the individual event details. Other organisations and BC branches have different policies. Please contact the named leader for the walk before travelling if you have any concerns.
Lyme Disease
We recommend that all attendees understand the symptoms of Lyme Disease and take the relevant precautions. For more information visit the branch website -

Special needs
Unfortunately, most walks will not be suitable for wheelchair users and pushchairs. Please contact the named leader in advance if you have any concerns about accessibility.

We have tried to include the What3word link for each event. To download the App visit: https://what3words.com/products/what3words-app
Public Transport
We aim to give as much information as possible, although unfortunately some of the Hertfordshire events are not easily accessible by public transport. Train times should be checked, as timetables change and engineering works take place on Saturdays and Sundays. In 2024 industrial action may also affect travel arrangements. We recommend using public transport for all events in London.
