Build a small, steerable Lego vehicle. (I'm not talking about Mindstorms, just ordinary motorized Lego.) Add some cheap video cameras (like those X10 cameras). Glue it together or tighten it up with zip-ties. Attach a very long extension wire for power/control (and video?).

Lower it over the edge of an interesting cliff or tall building and watch the video. If it ends up on a ledge, you can drive around and explore the ledge. When you're tired of that, drive it off the edge and keep going down. If it gets stuck, just hoist it up by the cable and move it over a little bit. If it gets really stuck, or damaged, or bits fall off, well, it wasn't that expensive to build, and perhaps it will amuse some climber who happens to find it years hence.

(Of course, you can rappel yourself down, but that requires skill and equipment and training and safety precautions and permission.)

       Very nice, a poor man's Rover. There are some too-small lava caves I'd dearly love to send it into, just on the chance there's a big cave on the other side of the little opening. I've often wished for something that would crawl and swim down the throat of some of the big springs in my bit of the Cascade Mountains, just to see what's in there. But that would take a more expensive rig-up.   

       I like this idea quite a lot. Nice one, egnor.

       Could it have a little motorized claw so you could collect samples?

       This is the first keen HB MacGuyver for which I have every necessary component at hand. Except the cliff.

       You could also use it for laying cables under your floorboards.
