For insurance and quality reasons, there's a maximum number of people that can be taken on a walking tour of Chester.  See below for more details.

The maximum number of people on any group walking tour is 25, although this may need to be reduced, depending on special needs / requirements. 

For ghost tours, I recommend a maximum of 15 people (for best effect), although up to 25 is possible.

If you have more than 25 people in your group, I will endeavour to provide additional qualified guides (please contact me for more details).
