First of all, thank you so much for getting back at me - yesterday I was working all day, and I had no chance to answer back. It's my first time planning a trip like this, on an unknown terrain/weatherwise by myself. I have no problem traveling on my own - had my share on europe cities all around, but it's time to move out of my confort zone :)
I'm prepared for the cold and snow (at least mentally I am!) - and I've been checking the map link you shared (and those timetables help a lot), I'm guessing not all hiking paths are open due to the snow, although I wouldn't adventure alone in the middle of forest terrain (not yet I guess).
This time I won't go for snowboarding (sigh) I would like to just walk around and enjoy the views, taking pictures (one of my passions) and getting a feeling of what mountain life would be, even for a short period. I'm not really used to snow or walking on it (in my country it's really rare) but I've been in czech republic for one year and I survived so...let's do this! I am now very inclined to make my base in Wengen (although I'm not finding that much hostels - I'll stay in a hotel then). From Wengen to Lauterbrunnen it would be 20min by train if I want to go to the other side of the slope (Murren Gimmelwald and Schilthorn) and being at Wengen, I'm closer to getting at First and Mannlichen (through Grindelwald Kleine Scheidegg). So the day I arrive to Interlaken, I plan to getting there early, I can walk around a bit and then go up, check in in Wengen and then go up to Grindelwald take the cable car to Kleine Scheidegg and First (is the First Cliff walk Tissot open at this date?) then go to Mannlichen and come down (I just don't know which part is possible to walk down due to snow or steepness - im used to run and walk a lot, but still).
On the other day, waking up fresh and rested I'd go to Lauterbrunnen Murren Gimmelwald and Schilthorn, what do you think? I'd like to see the Bachalp lake and Brienz, I don't know if or where do I input those ones on the itinerary :p
On the third day I'd pack and go to Bern through Luzern, spend some hours there and maybe go to Mt Pilatus (even with the backpack i know) and at the end of the day I'd arrive in Bern, meeting my friend, which will alow me to rest and being guided on saturday through the city.
So for now, it looks something like this:
Day 1: Arrival at Geneve Airport at 9am. Going by train to La Tour de Peilz through Geneve and Lausanne (hopping down in each one to walk around 2 hours each).
Day 2: Wake up early and go to Rochers de Naye, come down and go to Montreux and Challet du Chillon. Walk till La Tour and visit Vevey. My friend told me it's possible to try snowshoeing close to her place - if possible, I'm gonna do that :)
Day 3. Early bird goes by Golden Pass to Interlaken and walk by the lakes. Check in in Wengen. Goes to Grindelwald, Kleine Scheidegg and First. Mannlichen and then back down. (Hardi Kulm?)
Day 4: Other side of the slope, Lauterbrunnen Murren Gimmelwald Schilthorn. Brienz? Back to Wengen
Day 5: Check out and go to Luzerne, sightseeing and go to Mt Pilatus. Go to Bern and meet my friend at the end of the day
Day 6:Sightseeing in Bern (i'm trusting vitor for this day to show me around)
Day 7: Hop on a bus to Lyon and spend the night there
Day 8:Getting my flight back home.
Am I wasting too much time at some place or am I rushing aorund too many places that I'll stress out? I prefer to do things peacefully so if I have to filter, for my sanity cause, I will..
Also, if it's rainy/cloudy can you suggest alternatives at low altitudes? I'm not planning hard hikes (1-2.5 hours (straight,by day I can walk 4-5hours depending on the terrain/weather) is okay if the path is not super isolated or steep).
As I'll have the Swiss Travel Pass, I'm hoping it covers almost all the trips up and down, from tuesday to saturday
Thank you guys for being so helpful!
