Altberg (HB/ZH-015) offers a wodden tower Verein Aussichtsturm Altberg - Aussicht with nice views and a restaurant as well.
Another option is Lägern (HB/ZH-010) with a viewing platform facing South (-> Alps) (although the restaurant on top is closed due to renovation).
FM calling QRG is 145.500 MHz and I have no idea how busy the 2m band nowadays is. I’m only QRV on HF.
How do you travel around Zurich? Car or public transport?
I’m living at the foot of HB/ZH-10 and on the other side of the valley is HB/ZH-015.

I would say with a bit of patience and a decent whip antenna on your HT, four QSOs should be possible on a weekday. There are some chasers in the area who always seem to be QRV, also on 2m. A SOTAwatch spot will help. And there are always random (non-SOTA) people monitoring 145.500; not sure how many would respond to a CQ call in English though.
On a weekend, you should have no trouble at all and might even experience a mini pile-up, especially when the weather is good and lots of S2S are around.
I visited HB9 land last year (Interlaken/Thun area then time in Geneva), so a little way from Zurich, but found 2m to be fairly quiet up in the mountains. You may have better luck in Zurich, especially as you are quite close to the D and F borders, so aren’t reliant necessarily on local stations to chase you.
I monitored and called CQ every day at various times on the standard calling frequency of 145.500FM (standard for us in Europe anyway ) and managed 3 contacts in a two week holiday, two of which were French, just one HB station. As an American you may have better luck, as most Europeans probably choose to ignore Brit’s at the moment ha ha! I did find my calls in French and German helped elicit responses; certainly one French station spoke very little English, but my schoolboy French allowed me to converse for a good few minutes - at least, I think he understood me…
I also had some really useful help and HB9 advice from Paul @HB9DST so you may want to contact him for more up to date info.
As Manuel says above, if you are patient and perhaps post a couple of alerts/spots where you can, you should be able to activate, if not qualify your planned summit. I found mobile phone coverage was pretty good, even up 2000m summits, so you should be able to post self spots to help the chasers find you. I imagine a weekend activation would be easier and may result in the odd S2S.
Good luck & let us all know how you get on.
Paul/HB9DST guided Joyce/K0JJW and me to a wonderful activation of Selun (HB/SG-049) yesterday. Paul was on HF while Joyce and I made a bunch of contacts on 2m fm (mostly HB9 plus a few DM and one OE). Three S2S, so it was a good day.
I’ll try to write up a trip report at some point.
