Kamikochi/Okuhida 1 day (Matsumoto - Toyama)

Just wondering how practical it is planning a one day straight run in late April from Matsumoto to Toyama, stopping by Kamikochi to do its loop and then Okuhida Onsen's Yakedake for a dip of at least a few hours.

The thing I'm worried about most is the whole Kamikochi - Yakedake bus, and then Yakedake - Takayama bus, can't find the schedules for those so no idea if it's even doable at all. Thanks for any help.

Hi,
I think you can make one day trip from Matsumoto to Toyama(Toyama-City,right?).
But it would be bit busy.

Regarding Onsen(hotspring),do you think of Okuhida Garden Hotel Yakedake ?

If so,you need to chage the bus at Hirayu-Onsen from Kamikochi,and it seems to be bit far from the nearest bus stop.
Pick-up service by the hotel is only for overnight guest.
Then I recommend Hiaryu-no-Mori instead,very close to Hirayu bus terminal.

brief plan for example:
Matsumoto 8:00 (train and bus) Kamikochi 9:45
Kamikochi 13:00 (Nohi bus) Hirayu 13:25
Hirayu 15:30 (Nohi bus) Takayama 16:30
Takayama 17:15(Wide-View Hida,JR Express train) Toyama 19:30

other options:
Skip onsen soaking and have time to stroll around Takayama instead.

Or stay at Hirayu-Onsen/Okuhida Garden Hotel/other onsen Ryokan around Okuhida area for a night.

Hope it helps.

Woah, thanks for all the detailed info, big help! :)
