Need advice Kyoto->Tokyo

Hey guys,

I hope this is the right place to ask. My parents rented a camper van for 3 weeks and unfortunately a lot of unexpected things happened during the trip. They now have about one week left and need to make their way from Kyoto to Tokyo.

They would love to do some moderate/easy hiking and visit smaller cities, villages, or places that are less crowded and more relaxed. Do you have any recommendations for nice areas worth visiting on that route?

And one more question: since they are traveling by camper and want to stay at campsites, they’ve had trouble finding onsens or camping places with showers. Does anyone know where they should look for those or if there are any good apps/websites for finding them?

Thanks a lot for any tips 🙂
