In case anyone is interested, I'd judge it to be moderately difficult. Moderately steep, very poor traction, a ton of boulders and several ledges in the 2 to 2.5 ft. range to climb. These wouldn't normally be much of an issue but there just wasn't much traction available to get over them - very loose. We were warned by a pack of guys on ATVs not to try it but you know how that goes. About half way down, I was thinking maybe they were right. About a quarter of the way up I was sure they were. At the top I knew I was right.
The Lakes Basin area is really pretty and there are lots of trails that interconnect a dozen or two lakes.
