Hiking Solo in swiss or french aps

The French and Swiss Alps constitute several distinct regions, and different subchains. Asking if the Swiss or French Alps are easier to hike is like asking if the Appalachians are easier to hike in New York or Pennsylvania. That being said, walking along well established trails in the Alps is more a matter of physical conditioning than skill. The trails are usually obvious and well-marked in all but the most obscure areas. Once you ascend above the Alpine level (ie, few to no trees), it's very hard to get lost. And during the hiking season, you're rarely alone for very long. Unless you count my dog, the majority of the long hikes I've taken in the Alps have been solo. The easiest high Alpine hikes I've seen are above the resort town of Flumserberg in eastern Switzerland. You can ride a gondola near to the top, and once you get off, there's several kilometers of well marked and nearly flat trails. You will even see families pushing along strollers. If you want a little more of a challenge, you can skip the ski gondola and hike up the mountain, or you can ascend further, where conditions get a little more rocky and steep. Recommend going in September. It's still warm enough to prevent new snow accumulation, but not so warm that you have to worry about heat stress. Early October can also be a good time, but by mid month, conditions start to deteriorate fast.

It is really hard to get lost in Switzerland. They have 40,000 miles of trails with well maintained signs. In French or German:

We have done hut to hut hiking in both the Swiss and Italian Alps. It is nearly impossible to get lost as everything is usually very well marked and the distances are typically not that far. I wouldn't even think twice about going by myself - you will not be alone, nothing really feels too remote (I'm used to the Sierra Nevada mts. and the alps seem incredibly civilized compared to them!), and there are places to eat and drink. The thing that I love about hiking in the alps is that you can ride a gondola up, eliminating the difficult part of the elevation gain. If you spend your nights in mountain huts you can get meet wonderful people from all over the world, eat locally prepared food, and sleep under thick European comforters for $25 - $50 per night depending on the hut. I also love that sheep and cows are seen and heard (tinkling bells in the distance) and are friendly faces along the trails. No need really to take a guided tour in my opinion unless you want to do that for the first few days to get acclimated and then go off on your own.
Have fun!

Rina,
I like day hikes and am usually OK with going it alone, but stuff does happen like just slipping and twisting an ankle when distracted by a gorgeous view, so I try to be practical. At the end of this month I plan to take solo half-day hikes in the Jungfrau area and the Engadin/Bernina Pass area. The way I do it is to pick popular hikes where I expect a good bit of foot traffica compromise from the total nature experience I would like, but I will try for early starts. I also pick several relatively shorter routes over one longer route so if I have any type of problem I am closer to help, so half-day instead of full-day and don't stay out late. I also will have copies of topo maps with my route marked and (if I can find it), verbal descriptions of the route and its turns. With the aerial maps from Google earth, I have also found some hiking sites that map the route on a photo, so I am taking those as well to help visualize my route. After that, I just properly outfit with extra socks, rain gear, water, food, first aid kit, etc. Overdoing it, but makes me comfortable. I've never gotten seriously lost, just slightly off trail. I've only once felt a little uncomfortable in that I only saw one man on a trail near Mittenwald in 3 hours and he got ahead of me. I have read that some ski/hike towns and hotels in Tyrol Austria offer free daily guided hikes, but I haven't been there.
