Social Events and Guided Walks


We include some new sites as well as retaining favourites from past years. As well as their butterfly populations, all the sites are delightful places in their own right with considerable other wildlife interest and often historic or archaeological value as well.

There is no charge for the walks (except the walk on 4th June run by 'All the Moors Butterflies' team). Children and beginners are especially welcome. No dogs please as some of the sites have livestock on them.

Most walks are at the weekend but we have included some mid-week ones as well and aimed for a fair geographical spread. Except where indicated, all walks start promptly at 11.00 am; please take care to arrive in good time.  They are taken at an easy pace and end around 1.00-1.30 pm so a packed lunch may be a good idea.  

Many sites include steep or rough or wet ground so stout shoes, boots or wellies are recommended. Tell the leader if you have health problems that might affect you on the walk.  Please be aware of the growing risk of Lyme Disease and take appropriate precautions.  

If the weather is wet or unseasonably cold and dull, the walk will be cancelled. If you have a query about the walk please phone the Walk Leader.

As well as the walks listed below, the National Trust’s Large Blue site at Collard Hill in the Poldens will be open during the flight period (see the NT website for details).

Butterfly Walks in Somerset and Bristol contains details of 37 walks in the county with maps and details of when best to visit. It includes many that are not part of this year’s guided walks programme and suggest those sites where you are most likely to see habitat specialists. It is obtainable by post from Butterfly Conservation, c/o 12 Alma Street, Taunton, TA1 3AH. Price £8.00 incl p&p. Please make cheques payable to Butterfly Conservation, Somerset and Bristol Branch.
