The walk to the restaurant at Schynigge Platte is less than 5 minutes and paved. If she can’t do that amount of walking I’d suggest Wengen is really not a good location, as it would require at least that amount of uphill/downhill walking to get to and from lodging/train station. Starting point is Wengen railway station. From there you walk along the mainroad. At the Hotel Palace turn right and then left again. At "Ledi" you already have a wonderful view of the Lauterbrunnen valley. Continue along the wide path to "am Hubel". The last stretch takes us to the Hunneflue viewpoint after about 50 metres. Info for the panoramic hike from Grütschalp to Mürren. Lauterbrunnen loop hike: On top of the cliffs. From the Trummelbach waterfall to the cliff top. Back to Wengen and Lauterbrunnen. Information and map for the hike Trummelbach-Wengen-Lauterbrunnen. Walking tour from Lauterbrunnen to Stechelberg. Wengen and Murren are both car free villages and are slightly smaller than Lauterbrunnen. Murren is the highest of the 3. You can look across the valley and down a little and see Wengen. Staying in Lauterbrunnen you can have a great view of Staubbach falls which can be nice. Once you come out of the woods above Roseys Café the trail into Wengen is paved. Your other choice for getting up from the valley floor would be to walk all the way from Steckelberg into Lauterbrunnen (easy flat walking) and take the main trail from Lauterbrunnen up to Wengen. Uphill about 1 1/2 hrs. The journey time between Lauterbrunnen–Mürren Mountain Railway and Wengen–Männlichen aerial cableway is around 1h 28m and covers a distance of around 8 km. This includes an average layover time of around 57 min. Services are operated by Swiss Railways (SBB/CFF/FFS), Wengernalpbahn and Wengen-Männlichen. Typically 245 services run weekly 3. There are dozens of easy hikes with fabulous views (including a walk down Lauterbrunnen Valley where you will see at least 10 waterfalls) and many attractions in the Wengen area. You should plan to base your activities there since you are so wisely staying there. I have a 20+ page document of things to do, transport advice, etc in the Wengen #1. take the cable car up to Männlichen, enjoy the views over Wengen and Lauterbrunnen Valley and from there you can hike that lovely path to Kleine Scheidegg, and catch the train up to Jungfraujoch. You can either take the train back to Wengen after Jungfraujoch or choose to hike back down from Kleine Scheidegg, which is an amazing easy YrW8Gn.
