I found this site for rating caches for handicapped people. I know I've found caches rated 1/1, which required the services of a Grand Canyon burro to reach.

Hopefully this will help (link added to the links section as well):

Looks like a good resource. Perhaps it warrants a place in the Links section.

Thanks! This is extremely useful. My oldest brother uses a walker and/or wheelchair due to illness and would like very much to get into geocaching but a lot of the terrains labeled with a single star are not wheelchair accessible. I really appreciate this link.

And this site also allows any cacher to rate a cache for handicapped accessibility, not just the cache owner.
