The next day, we headed to Matmata. To get there, we decided to take a shared taxi (louage) - in this case, it was a bit of a miscalculation. On our way in to Djerba, we had crossed on a causeway to the island. However, it didn't make sense to go this way when heading towards Matmata, so we had to take the ferry. Unfortunately, the ferries don't run very often, despite how popular a route it is. We ended up waiting close to two hours before we finally got on a ferry. Turns out, the government-run buses that we could have taken have priority boarding on the boats - and we actually saw several of the buses go ahead of us.
