A proven approach is using a tracked robot with tracked so-called flippers. This is used for example on the iRobot Packbot or other robots used for RoboCup Rescue a lot. Examples:
Mobility test of iRobot Negotiator @ RoboCup Rescue 2010 - YouTube
Final run in the RoboCup Rescue German Open 2010 - YouTube
Of course, these robots are rather heavy and expensive.

An example of a very mobile robot based on a <100$ RC toy can be seen here:

And then there are of course elegant and lightweight approaches like the BlueBotics Shrimp:

(There are also some vids on YouTube)

..And there are some more small stair climbing robots on YouTube:
Stair Climbing Robot - SM.mp4 - YouTube
Stair climber - cute - YouTube
(There's quite some more LEGO NXT based and similar robots to be found).

You might also want to look at using an RC rock crawler as a base.
