Back in 2002,I took my family to Engelberg (I used to live in Weggis back in the '80's and so know the area very well).
We went over the Jochpass and down to Englsten Lake and I took a photo from the lakeshore to the right hand side,towards the Grindelwald Alps range,as shown on your photo - have a look at the photos - pbase.com/eiger and Switzerland.
It is a lovely area and we must return.On another note,I read somewhere that just below where you took this photo,on the hillside,there is a huge concentration of radioactivty - don't know why....
