All trips that are resuming will have a new Covid-19 information section that sets out any changes to the itinerary or inclusions, along with the specific safety measures being introduced on that trip.
For example, have a look at this trip: Introduction to Mountaineering on the Isle of Skye.
If you have any further questions your local host is very happy to answer these via
your booking.
