Your guide will be waiting for you once you have passed through the port security area at Muelle Alfonso XIII, holding a sign with the lead traveler's name so you can easily identify them.
The tour will finish at the local food market, where you can choose to stay and enjoy some more local specialties at your own pace.
If you prefer, your guide will be happy to accompany you back to the port after the tour. You can decide which option you prefer on the day of the tour.
