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...

17th Nov 2018DoBIH User Survey 2018
Take the survey
If you use the hills database or the Hill Bagging website it would be very helpful if you complete this user survey. It will take about 10-15 minutes.
I know many people dislike surveys but this is the first we've run since 2010. We'll use the results to evaluate how well we're meeting your needs and to drive future development of the database. If you're entirely happy with things as they are, we still want to know.

5th Oct 2018Important I have had a number of reports recently from people who have received troubling emails where the sender claims to have hacked into their email or their computer, and quoting their hill-bagging password as evidence of their claim. I believe the sender has obtained a list of email address and passwords from hill-bagging at some time in the past. This must have been over 2 years ago, because at that time I became more aware of security issues and took steps to encrypt the email addresses on the database and "hash" the passwords (which means the passwords can't be decrypted even if you have the hash key). Also at that time I stopped sending automated emails confirming the username and password when people registered on hill-bagging, because someone pointed out that sending email and password details by plain email was not secure.
I am sorry if you have been the recipient of an unpleasant email. If you registered on hill-bagging more than two years ago I recommend that you change your password on hill-bagging if you have not recently done so, and on any other website/system where you have used the same login credentials.
Regards, Simon
