Well, most ferries stopped accepting foot passengers unfortunately. There are a few P&O sailings still accepting foot passengers.

It’s quite cheap when you take it as a cyclist I think.

Eurostar doesn’t stop at intermediate stations any more.

P&O still take foot passengers on some sailings:

Oh gosh, really? From the P&O website it looks like there are only three journeys a day for foot passengers (still very few, especially during summer).

I hope it is up to date.

Thank you!

I just saw that too, just corrected my post ;)

Slight improvement than, luckily!
