Yes. The price of the tour does not include flights and we do not provide a flight booking service.
We sell individual self-guided trips. This means that you are not travelling with a group and there are no fixed departure dates. You are free to start whenever you like (subject to availability), and you can travel to the starting point by whatever means you like. This also gives you the flexibility to find the cheapest flights/train tickets. Google Flights is an excellent resource for comparing flights to any destination.
Please note that we always recommend that you wait until you receive your final confirmation email from us before booking your flights.
