Suggestions on 3 weeks packrafting?

Hi all,

I am planning to head out for around 3 weeks now in March and the plan would be to packraft / hike. I have quite a bit of expedition experience from earlier (cycled to china from turkey) and so on, but had some physical issues during the last few years that I am recovering from, so the idea with this trip is to head out and check how my body copes and enjoy nature. Meaning I dont want something to physically demanding and maybe not too remote if my body starts shutting down. Not to remote, but still as few people as possible.

Would love to hear some suggestions from people here ? Open to all countries.
