Hi Brian,
Thanks for the pic, that is indeed Gotthard G.C. at Realp with the 2nd Green behind, the 3rd Tee on the hill, the 3rd Fairway to the left. The 4th Fairway in the foreground leading directly to the 4th Green below.
Your photo is taken looking down the hill from the 4th Tee and is slightly misleading as it doesn’t reveal the true inclination of the slope which at this point is roughly 1:5. or 20%. and gradually reduces.
I’ve attached an old pic of “yours truly” on my only visit in the late 90’s (you can tell from the white shoes and the Taylor Made Titanium Driver) , having a swipe from the then 4th Tee in Realp. In the background one can get an impression of the elevation and steepness to the valley below.
If one slides over to the right of your pic you can just see a bunker of the 5th Green, which is at the top of the slope. The 5th tee is near a bright green net at the bottom. This is the hole I was referring to, the "South Wall" 5th.
The inclination at this part of the slope is much steeper, quite hard work to walk up at this altitude (about 5’200 feet above sea level).
It appears they have shortened the hole significantly since I played there. If my memory serves me right the original Back Tee was tucked near the bottom of the hill where it was very steep and the hole was much longer. However due to the steepness of the initial slope, maybe 1:3 a driver off the Tee was unthinkable and the Green virtually unreachable, thus in my memory this was a Par 4, albeit a short one, as was was implied on the course card.
They’ve sensibly shortened it further up the hill and to the side to make a 140 yards Par 3 and have constructed a raised platform for the Tee to make the hole more playable.
This photo lifted from their website shows the new Tee.
The swiss golfers, who love their “Bergwanderung” have no qualms humping it up and down hills, as you can see on your pic there are plenty of golfers out on the course.
