The old street near longxing temple (now Ziyang Street, formerly Jiefang Street) is very tasty. You can go for a walk. There are many seaside snacks in Ziyang Street and the west street that crosses it! It's convenient to go to the Great Wall after walking to the finish line. The Great Wall is not entirely new, but it has been renovated in recent two years, and a spectacular staircase has been built at the East Lake. In fact, the wall near Ximen River is quite primitive, especially now that there is a large lawn beside the river, it is very comfortable to go for a walk in the afternoon with good weather (it is best to bring a dog, hehe. )
In a word, the west of Linhai is the old city, which is very traditional. For example, during the Chinese New Year, you can see them cooking sugar water to make fried rice and sugar. As for the temple fair, there is no temple fair in the urban area, but there should be one in the towns below.
There is a resort in Niutoushan Reservoir, and many people should go there during the Chinese New Year. It's cool to go fishing there in summer nights.
