Lucky you Ruthiebabes - sure you will love it. This is the third year we will have been back - we have 2 weeks booked for June (last holiday before we have to go in the school holidays as DSs are 4 and 3) We are in that location too (ie nr St Jean D'Angely)
Can't really help re restaurants as we just tended to stop and eat when and where we could! As for days out, here are some off the top of my head!
Zoodysse is a nature reserve/zoo where you can safely see roe deer,wild boar, wolves and many other European animals in their natural habitat in a forest setting. Great on a hot day to walk around and always been lovely and quiet when we have been there - www.zoodyssee.org
Surgères is a market town with a beautiful Château in parkland. Market on Tuesdays, Thursdays and Saturdays.
La Rochelle - Good for eating ? and shopping! The Aquarium is great but go early esp if its a rainy day!
Royan ? DH loves all the maritime stuff here including old rope making buildings, restored boats etc etc.
Good beaches include Chatelaillon- Plage, Fouras & Royan.
Cognac ? lovely town to look around. Do one of the Cognac Houses tours - included in the Hennessey tour is a boat trip across the river and Remy Martin includes a train ride for children.
Marais Poitevin is an area crisscrossed by an system of canals - quite nice to see. Boat trip available from Coulon.
Saintes ? nice town with lots of museums, amphitheatre and abbey.
Ile de Ré is one of our favourite places to visit. We like St. Martin for pottering/shopping/eating! Nice little harbour for the kids to watch boats too. Lots of places to hire bikes from.
Ile d'Oleron also has nice beaches.
La Palmyre Zoo - even if you don?t normally like zoos, this one is great.
This is a really good guide book that has helped us find out things to do:
