Izu food, nature, off-beat, culture?

Our family of 4 (kids 11 and 14) have two days of Ito-based car hire to slowly enjoy the Izu Peninsula in early October.

We welcome suggestion of highlights that we could experience - even a rough itinerary if you are feeling generous!

We're interested in local food specialities, nature-based activities (such as rotemburo, Kawazu 7 waterfalls, Jogasaki coast), anything just off-beat (like the Inquisitive Girls and Boys Museum) or unique cultural activities, sights, or experiences.

All suggestions welcome! Thanks in advance

Izu Shaboten (zoo) is fantastic, they look after the animals well and you can get in with some. Also great views of the bowl mountain and ocean. Treat yourself to a cactus burger and cactus icecream, both very pleasant (not much cactus in them, really).

Shuzenji is a nice town (wasabi icecream, fantastic, also deep fried fish skeletons as bar snacks in one place, surprisingly good). But not much for the kids to do maybe.

A lot of fresh fish there, we stayed at Taisekan for a few days which I would recommend for value and food though the town (Ajiro) was comatose quiet.

I don�ft know Izu peninsula too well. But do agree with Shuzenji and would also try for an onsen on the coast. I have wonderful memories of one in Imaihama.

I also remember going to a wasabi plantation somewhere between Shimoda and Shuzenji.

I don�ft remember when you go, but if it is late Feb/early March the first sakura in Kawazu are flowering.
