Kanazawa to matsumoto ideas?

1 day was planning on alpine route but having second thoughts due to weather and expected very busy and queuing.

Now thinking what other options.

Jigokudani - apparently quite alot of effort for an hour seeing monkeys

I'm sure I saw a coastal route option somewhere?

Get to matsumoto early? Or just go straight back to tokyo for an extra day before we fly home

Already been to tatayama, shirakawa-go, kyoto osaka..
