maps and handbook:
in the tour start briefing, when the bikes are assigned, you will also receive a tour handbook and maps of the areas crossed by the tour. These will be your navigational tools. You should study these even if you intend to follow the guide at all times.
knowing where you will be going and what to expect, will amplify your enjoyment and you will get so much more out of your tour.
bring both with you at the evening briefing. there will be a short briefing every evening before dinner to talk about what happened that day and to discuss the following days ride.
