Social Events & Guided Walks

Guided Butterfly Walks 2017

As well as their butterfly populations, the sites in this programme are without exception delightful places in their own right with considerable other wildlife interest and often historic or archaeological value as well. So, even if the occasional walk may not be in the most perfect of summer weather, you will still find plenty to appreciate.

Children and beginners are especially welcome. No dogs please as some of the sites have livestock on them. There is no charge for the walks.

Most walks are at the weekend but we have included some mid-week ones as well and aimed for a fair spread across the county plus one at Cerne Abbas Giant Hill in Dorset. 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 or boots (wellies if it’s been wet) are recommended.

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 or, if no contact details are given, phone John Andrews on 01278 426500. Any unavoidable last-minute changes will be posted on the Branch website

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.
