Thanks Mr Giuseppe for the tips about Santallago. If you want to spend a day in open air for a picnic or barbecue Santallago is for you.
It is located 1 h far away from B&B Sunrise. The Park is near Monte Serra offers a large green space where you can relax and picnic area or if you want you can use the barbecue tools with wood.
The place is rustic and there is restaurant. it seems it takes 6 € each car to enter.
