Where, how much do you want to spend, how far to travel? There are many out there. Some cool ones can be found at the website for Working with the Artists. Many of the leading photogs of today offer travel tours. I think, although it has been years, that National Geo offers some as well. Also local camera clubs are a good resource for day trips in your local area. There is also a Forum here called Member Meetings... that might post this too as well to get more replies...or if you want a particular kind of tour, try posting in that Forum for those people tend to specialize and might have insight into a tour on that narrow kind of subject matter.
