Looks like a nice place! Althoug perhaps it lacks a bit of grass and I guess taking a swim in the lake is forbidden?
How was Tarot? I've just learnt about their tour, I might go in Paris.
The place is amazing, the best festival area I've seen. There's enough grass and a nice sandy beach, and swimming in the sea is allowed too (you can watch a band performing on one of the stages while swimming around ). From time to time a huge ferry would pass by just 100m from the shore - it was quite surreal to see them towering above the stage.
Tarot were pretty terrible, the least entertaining band I saw at Ruisrock. The sound was alright, but the performance was pretty tired and lifeless...
