Often overlooked number 5 is right there when you first walk up to the Lowers. It's a very short route from the lowest point of the Lowers up to the first large ledge. There are several bolts there and some anchors on top. It can be led, top roped, bouldered or even aided depending on what you want to do. (I'm not sure about aiding it but the Craggers Atlas gives it an A1).
It's actually a pretty fun boulder problem with a reachy start and some good crack holds and jugs. It's laid back a bit so it's mostly power unlike most routes at the Lowers. It's worth a try if you are there. There is a route directly above it called Five Alpha which I believe is a full on aid route.
It's at the lowest point of the Lowers when you first walk up and well, there is a real small 5, a small 5, and a big 5 painted on the rock so you shouldn't miss it.
Lots of bolts and anchors. If you boulder it a single pad should do. A spotter would be good since you will fall backwards if you come off at the top.
