I'll be spending 2 full days and 2 half days in Geneva towards the end of July. What are some of the sites that are must sees and are there any web sites where i can get info on what to do there?

rayoflight,
Geneva itself has a wonderful web site full of useful information and suggestions.
You might want to have a look at it.

I'd consider a cruise on the lake and a stroll through the old town as absolute musts.
Not sure, what you're interested in? Museums, shopping...
You will most likely find some brochures for visitors with useful recommendations at your hotel as well.

Hopefully, the weather remains as gorgeous as it is right now.
I hope you have a hotel with A/C, because it has been the hottest June ever so far in Switzerland. Temps around 95F...
August 1 is the Swiss National Day. Most probably, there will be fireworks on the lake. Just in case, you should still be in Geneva.

Have fun!

Lots to do and see. Take the boat to Montreaux and or Yvoire - both beautiful towns. If you like to hike, take a trip up to the Saleve Mountain; can either hike up it (takes about an hour) or take the telerpherique. Bring a picnic and a bottle of wine and admire the view of Lake Geneva and the Alps. Amazing! Ursula is right, it has been a scorcher so far this year. But no humidity, so that is a plus if you are coming from the States.

Just read on the Fete de Geneve (one of this summer's highlights) site that the fireworks will take place on July 31 at 11 PM. Not to be missed, if you're still there.

For trips on the lake, see www.cgn.ch. The company's fleet includes paddle steamers and the ships have good restaurants.

Previously posted here, and now 15 months old, this restaurant review from the NYTimes is worthwhil reading.

As always, registration is required to read it, but it is free.

If you are there on a Saturday ... go to the morning open air market at Vevey town square. In late July/early August the Marche de Folklorique should also be going on same place - where you purchase an empty glass upon arrival and get it refilled to your pleasure until Noon (red, rose, white from varying local vineyards) while you shop for bakery, flowers, meats, cheeses, fruits, vegetables, clothes. An hour outside Geneva then a 5 min. walk from the train station.

While you're there be sure to stop at the myriad sidewalk cafes for an ice cream or ice cream sundae - started my everlasting love of European (well, Italian and Swiss) ice cream. Wish I could remember the name of the restaurant in the old town area where I had the best swiss fondue (all to myself as my traveling companion did not like cheese - can you imagine?) First time I ever saw a dog in a restaurant, laying under the table (this was my first trip to Europe).
