Welcome to the online version of the
Database of British and Irish Hills (DoBIH)

There are many recognised lists of hills and mountains in Britain and Ireland - all the well-known lists and a good many of the less popular ones are covered here.  Click on the required list name on the adjacent map, or use the mountain search facility.

You can use this website to log your own progress against these lists - simply register a Username and Password (free), and follow the instructions on the registry page.

Please note that inclusion of a hill on this site does not necessarily mean it is accessible.  In particular, some hill summits are on land where there is no public right of way nor open access.  Permission should be sought from the landowner where access to a hill is through private land.

You can view a log of recent changes to the DoBIH - some of these changes are applied to this website before they are generally released on DoBIH.  Refer to the Database Notes section of the DoBIH website (www.hills-database.co.uk) for version release notes and other changes to the database.

The survey reports from the DoBIH survey team are available here for download.  A number of people have asked if they could contribute to the running of this website or the DoBIH.  I would like to direct such generosity towards the DoBIH Fund which goes towards the development of the database and purchasing and operating survey equipment - please use the button below...
