The best place for a picnic when the weather's nice, we love sitting by the lake and chilling. Not too many people on weekdays. See dancing Japanese "Elvises" at the entrance on every Sunday!
Great for picnics and walking. There's also a lot of joggers, so if you're into a little exercise, it's a great place for that too. Best to go in may or October.
Bring a blanket so you can have a nice picnic during plum season. They don't have a lot of picnic tables.
