Hi,

I'll be in USA (for the 1st time) for a conference at Salt lake city (SLC) on 20th of Nov. I'll be flying from Singapore to San Francisco (SFO) and most likely taking Delta air to SLC. After the conference, I intend to visit some places. I've around 10-11 days. I'm thinking of visiting Yosemite, Yellowstone and the Grand canyon national park. Of cos, it's not possible to visit all these places so I wondering which is most convenient and worthy during that season. I've checked and I've the impression that without a car, it seems to be very inconvenient. I'm travelling alone so I'll be using public transport.

Thank you very much.

Tricky one this. I've a feeling Yellowstone could be pretty well shut up for the season by November but you can check here.

Without a car you've got problems. Although you can get to all those locations via public transport once you're there I think it's going to be tough. If it's is possible for you to rent a car I'd head down the I-15 to vegas, Grand Canyon, Bryce Canyon, Zion and if you have time left drive to Canyonlands and Arches.

If you have no option but to use public transport I don't think you're going to have an easy time.

It would definitely be best if you could rent a car. However, if you are going to depend on public transportation....San Francisco probably has the best. There are lots of things to do in the city and outlying areas. You could also arrange for a tour bus to take you to Napa Valley and Yosemite.

howefortunate is right, although I don't know much about Utah. You might consider taking a train to certain locations, but one you're there it will get considerably trickier. That having been said, all those national parks are definitely worth it!

I've never heard of anyone going to these places on public transportation. You can rent a car in the local areas. It's best that you get one, saves you some hassles.
