Hi Helen
I don't know that particular site but in 2006 we spent 2 very pleasant weeks at Camping Cavallino which is in the same area.
The Jesolo Peninsula stretches between the Adriatic Sea and the Venice Lagoon to the North of Venice. The Adriatic side is lined with campsites, including Cavillino, which stretch along the sandy beach which slopes very gradually into the warm Adriatic.
There is not a lot to see on the Peninsula, in my experience, but it is an ideal place for visiting Venice as a regular ferry departs from Punto Sabione (sp?) at the southern end of the Peninsula.
If you look on ukcampsite.co.uk you can read my review for Camping Cavallino, including our tips for visiting Venice, on the campsite search section. There are other reviews for other sites in that area too.
I hope this helps.
Tim
