If you are in Zuerich, Uetliberg is a good option I cna say. Almost near to the top you have aplace to camp and put up a tent and it is safe there I feel.

Many thanks!

(Un)fortunately we are based in Geneva.

But why not, we could try this option as well if I don't have other ideas. It could possibly be even higher than 800-900m.

You could probably pitch your tent at the top of the Jura. Just find a secluded place and maybe don't do it at 2 in the afternoon. once it's dark I doubt it's a problem. Otherwise there must be loads and loads of nice places to pitch the tent, but sure, you might not want to be on the rocks in Chamonix above 3000m!

Enjoy!

I used to to do camping on the Saleve when I was younger, there's some nice and calm places. Just think to let the place in same state you found it (as if no one was there...)

and be careful with ticks, ghosts and extraterrestrials and also the devil as he has a cave up there....

Thanks for your reply but not sure I'll go there after your "serious" post :) What if it's true after all?

ticks and devil are true.  Ghosts and ET are for your stories before sleep  ;)

Don't worry about the ghosts: there are so many vipers in Salève that they won't dare to come to show their lack of faces....

A good time to do it is also during the Perseids meteor shower to optimise camping + 'scenicness', however these are in August so am not sure if you would like to wait that long. Here is a link to a past such activity:

yeah, if you're interested by astronomy, it's a good place

Speaking of asrtonomy and camping  . . . 

BELGES AU CLAIR DE LUNE

Deux Belges installent leur tente dans une clairière et se couchent pour dormir.

Quelques heures plus tard, l'un d'eux réveille l'autre et lui dit :

- Regarde dans le ciel et dis-moi ce que tu vois.

- Des millions d'étoiles !

- Et qu'est-ce que ça veut dire, selon toi ?

Le Belge réfléchit à la question un instant et dit :

- Ben, astronomiquement parlant, cela veut dire qu'il y a des millions de galaxies et des milliards de planètes dans le vaste espace.

Astrologiquement, cela me dit que Saturne est en Verseau.

Pour l'heure, je dirais qu'il est quatre heures du matin.

Théologiquement parlant, il est évident que Dieu est tout puissant et que nous sommes petits et faibles.

Météorologiquement, il semblerait qu'il fasse beau demain.

Après s'être fait dévisager par l'autre Belge pendant quelques minutes, il reprend :

- Quoi, qu'est-ce que j'ai dit de mal ?

- Pauvre con va ! Si tu vois le ciel, ça veut simplement dire qu'on s'est fait voler la tente...

Take the bus to Solalex. From Solalex, hike up the obvious track, passing two nice resturants, continue up straight ahead (Left a bit) and camp just about anywhere. The next day, walk down the other side of the pass. via debordance. You end up near Sion.

It's not a long or hard walk, but miles from anywhere. Nice place to camp, good views etc...
