You don't have to pre-book activities until you join your tour. While on tour, your VagaGuide will advise you when you need to book an optional extra.
β οΈ IMPORTANT: The only exception is the Skellig Michael Island landing option. This optional extra is only available on the 12 Day Vagabond Giant Irish Adventure Tour. It requires prior booking at least 45 days before you arrive in Ireland.
For all other optional activities, your VagaGuide tour guide will discuss what's available on Day 1 of your tour. They will gauge interest from the group for each experience and keep you informed as you tour about when you need to book and which activities require cash.
You can also check what optional activities are available on your itinerary.
