Mürren or wegen or lauterbrunnen for solo traveller?

First Trip, Solo Female Traveler, Need Hiking advice - I would suggest you contact Denise at the Chalet Fontana in Murren and inquire for a room. Denise is a great source of information for all of your questions. She can guide you to hikes/trails that are suitable for you, and give you up to the minute details including weather.

Murren, Wengen and Lauterbrunnen "Valley" are all very very close and all visible from the other. You really can't go wrong, but I personally would not travel to the Swiss Alps and choose to stay in the "valley" between the massive mountains. Views are all around you so asking for the best views is really a question that can't be answered. The best views are all around you because you'll be right in the middle of them all.

We just returned from that area, we had a car so we stayed in Lauterbrunnen. We hiked from Mannlichen to Kleine Scheidegg, and Glutschap to Murren on the next day. They were both gorgeous hikes, the weather was beautiful for the Murren hike, but a little overcast and grey on the day we were on the Wengen side.

The walk from Glutschap to Murren is very easy going, anyone in walking condition can do that. Mannlichen to Kleine Scheidegg was also easy going. Had it not looked like rain, we'd have walked from Wengen down to Lauterbrunnen instead of taking the train. Both walks had amazing views.

We also walked each morning and evening through Lauterbrunnen valley, along the streams.
I think the view from either Murren or Wengen is similar, just different sides of the same valley.
All paths we took were very clearly marked and certainly not crowded. But there were enough people that you don't feel completely isolated or alone.

Good luck, and enjoy your trip!

To answer the wildflower question, yes, you should see some. They are usually in continuous bloom from late spring until the fall weather changeover, usually in October. The intensity of the colors varies depending on the time and weather.

My favorite is Murren. We loved it so much we went back a second time, and I could go back over and over again and never tire of it. Murren is 5000' up and literally surrounded by the Alps, enveloped by them. The views you get, wherever you are, are mind blowing. You feel like you can reach out and touch them. Very easy to go for walks/hikes on the groomed paths from Murren. Murren is also car free, except for a few "work" vehicles.
Lauterbrunnen is a nice town, but being on the valley floor wedged between two mountains, as Tim said, I found it to be dark, full of cars and you have to look up, very high up, to see the Alps.
We passed through Wengen and it looked nice but seemed more commercial than Murren, and was full of tourists.

I personally think Murren is the most pristine of the villages - Less tourists (that's a good thing for me) and less commercialized.

I agree with Tim on Murren. Just stayed in the apartment of Chalet Fontana. Denise is a delight, so helpful.

I second Murren and staying at Chalet Fontana. Perfect in every way at a reasonable rate. Enjoy.

Absolutely agree about Denise and Chalet Fontana.

She knows the trails, I forget if she won the Woman of the Mountains footrace, or only participated, but she knows her stuff. Her coffee table has plenty of good information, too.

It is unlikely you can get better value for money in the Lauterbrunnen Valley than a stay with her.

I agree with the above comments, though I'll add that it also depends on what you want to do. If you primarily want to enjoy one place, Murren is perhaps the best. Others, however, want to explore lots of different places, so that's why we choose Lauterbrunnen as a hub from where we can get to lots of places. However, as someone said, you can't go wrong with any of the places.
On disagreement, though, and that is with someone who considered walking down from Wengen to Lauterbrunnen.
Walking downhill sounds easy, right? Ha! Try it for an hour straight. Years ago I was 40 something with a 14 year old son with me. We decided to walk downhill from Kleine Scheidegg to Wengen. After an hour we BOTH felt the stress on our shins and ended up very sore.
If you try these walks you can't go wrong: Mannlichen to Kleine Scheidegg, Grutschalp to Murren, First to Bachalpsee and back.

Sarah,

Based on the criteria you mentioned, I'd have to agree with the others that Mürren is probably the best choice. Wengen tends to me more "upscale and pricey" (at least IMO). Lauterbrunnen is a good choice if you plan to explore both sides of the valley, as it's the transportation hub for the area, but staying in Mürren will provide more spectacular views.

One hike that's easy (it must be if I can do it) is to take the Allmend-Hubel Funicular up the hill from Mürren and then hike (walk) down through the alpine meadows, whilst enjoying the sound of cow bells in the afternoon sun. I haven't tried it yet, but the hike from Mürren to Grütschalp is also reported to be quite easy.

You could also walk down the small paved road to Gimmelwald (as featured in Rick's TV shows), and have a "cool one" at the Mountain Hostel or the Pension Gimmelwald.
