To Carrigain from the South
There is an extremely old route to the Col on the west side of the Captain. From there it is an easy walk over to the pond. I was up there about 4 years ago and the very old original flagging is bleached out cotton twill surveyors tape. But, it has a bit of more recent plastic flagging, quite obscure, but traceable when the leaves are down. It may be a fun whack with leaves on. The route runs high up on the western ridge of the valley through which the old logging roads and log yards run. This valley is accessable from the very end of the Sawyer River road. Park at the Sawyer Pond parking lot at the end of the road and make your way up the very nice logging road which diverges to the right soon after the gate. When you come to the bridge that seems to be to nowhere, stay right and make your way into the valley along the logging roads. When you have gone about as far as the old roads can take you, turn left (west) and bushwhack across the stream and directly toward the western valley wall. About 1/3 to 1/2 the way up the ridge line you should encounter the line of old flagging. Turn right and follow the flagging slowly up toward the Captain. You will reach at point near some big ledges where there will be just a mass of tapes tied to one tree, and you can look across and see that you are above the cliffs on the right of the Captain. The Captain will be only a stones throw (please don't) away from you . From there it really gets fun. The route goes directly up through a narrow flume onto the col. When I was there, the flume was very low on water so the going was not too bad. Once up and out of the flume, you will be in a nice mixture of open woods, and white pine new growth. I was there with only my two labs so looking for flagging was a bit of a pain. Much easier with hiking partners who can say "I see another one". I lost the flagging a lot in that area and wandered around a bit which of course was just what my hiking partners wanted to do any way. Incidentally, this trip started at the Sawyer Pond trailhead off the Kanc, and was quite impromptu.
If you want a partner on this, I just might be game to go back in.
I do know a quicker way in than by following the logging road from the gate, but it difficult to describe. It involves walking up the Hancock Notch\Sawyer River Trail with a short bushwhack on old paths over to nowhere bridge.
