To the South of Lyon, the "Island of the Round Table" in the middle of the Rhône offers a fantastic escape from the city. While the East side is exposed to a lot of noise from motorway traffic, the inside and West shore are gorgeous, and the southernmost end is a nature preserve.
The river flows by at a steady pace, making it a good spot for a reaction ferry similar to the ones in Basel. Fair play to the locals, they thought that too!
Bridges now do the job - though the suspension bridge from Vernaison isn't doing too well. Built in 1959, it needs replacing and until then, traffic is limited on it so as not to overload it. This hasn't been helped by the North side of the island being an industrial estate.
In the centre of the island, one finds a ruined farm, the Ferme aux Loups. One thing @teamroquette likes to do is geocaching, and so we looked for some, but the most elusive geocache of all was the namesake of the island. There are pictures of a round table associated with the island on Google Maps, but we missed it. That said, one Google review also mentions that they couldn't find it, so who knows.
We did find these interesting and somewhat imposing water level meters though. Lay on them to measure yourself... and get the wrong answer!
The Swiss city of Basel lies on the border with France and Germany, and, as it's Switzerland, it hasn't changed hands or been attacked much (though the French did use Basel as target practice for a new cannon from their fort at Huningue once). It has a well-preserved historic centre, and, with the Rhine's current being consistently strong, it has a rare form of transportation.
This little ferry has no motor. It is tethered to a wire that crosses the river, and a lever at one end of the tether on the boat is all that's needed to turn the boat into the current which does the rest.
It's incredibly simple and easy! For a more engaging version of the story, here's a video by The Tim Traveller.
While I rode the boat with my sister, I continued upstream alone to another crossing, a bridge which doubles up as a dam for hydro-electric power stations on either side - or Kraftwerk as it's known in German.
Unlike in Basel, the Rhine at this point is an international border: Germany on the right-hand side, and Switzerland on the left-hand side. But with Germany and Switzerland being signatories of the Schengen agreement, this is what the border looks like:
The Rhine sees some impressive barges navigate roughly between Schaffhausen and Rotterdam, so there is a rather impressive lock next to this dam and the Kraftwerken. This is the view downstream from the top of the lock, with what I suspect was a border post on the right? I don't know, but I seem to remember that black and white stripes had some significance.
