Water Taxi from Caminha to A Guarda

Several companies now offer the crossing from Caminha to A Guarda, and the ride takes around 20 minutes. The schedule varies with the tide, so you'll need to check locally or call ahead -- your accommodation in Caminha will almost certainly have the timetable posted, along with a link to make a reservation. Bikes are accepted.

The crossing itself is pleasant, especially in the morning when the estuary is calm. You're moving from Portugal to Spain, so adjust your watch forward one hour when you land. If you're waking at the same time as the day before, expect it to be darker than usual.
