2-day walk/hike idea in Dordogne?
 

I live in the Haute Vienne but I have a friend coming to visit in February and we would like to do a two-day hike somewhere nice. I can only leave my farm for one night so the idea is to drive somewhere early morning within about 3 hours from 87330, walk for the day and stay overnight, then walk the next day, then drive home.
Anyone have an idea of where to go? I was thinking Dordogne area. Not sure if it has to be a loop so we can get back to our car or if we can do a one-way and hitchhike back.
Prefer a nice mix of nature and interesting old villages. 25kms or so per day.
