Activities for 4 days in Takayama and around

Hi there,
I want to spend around 4 days in the greater Takayama area end of January, coming from Tokyo by bus. My plan is to stay in:

1) Okuhida Onsen (1 night)
--> Just looking forward to the onsens in town, but are there any other acitivies like hiking, snowshoeing etc. that are possible and accessible without a car? Any guided tours that could be booked?

2) Takayama (2 nights)
--> One relaxed day in Takayama
--> Visit Shirakawago (from Takayama, would have been interested to stay in a farmhouse, but when I last checked, everything was already booked out).

Do you have any additional tips on activities or places to see during this season around Takayama?

Thanks!

In the middle of winter… I LF you have the time I would do Ainokura instead of Shirakawa. But can be aPIA to get there w/o a car.
Otherwise in Takayama ther is Hida folk village. I probably wouldn’t do both a real village and the folk village

I would stay an extra night in Hirayu onsen and soak in the water for hours on end.

Thanks!
I did not have Ainokura on my list, but this seems to be a nice alternative instead of Shirakawago. Bus connections look decent enough. But yes, I also did consider just staying the Okuhida region for another nigt.

There are other places, but you really need a car. For example, the Hida Great Limestone Cave, or the Utsue 48 Falls. Not exactly the time of year I'd love to go to the falls, but it's an option.

Shirakawago is a lovely place to visit but very busy and with an underlying feeling these days as a cultural Disneyland. I'd definitely suggest visiting Shirakawago but then (if you can) travel a bit further and stay up at Ainokura. We always stay at a place called Goyoman in Ainokura - a really nice family run Gassho-Zukuri run by a lovely family.
