Wyman Mountain is an absolute winner!
I have not yet had an opportunity to climb Buck, Bear and Saunders, but have been up Wyman twice.
The first trip we started from Lindsay Brook, and made our way up the long NE ridge of Wyman. This was beautiful, and reminiscent of other hikes in that area with large sections of open rock and great views. The summit of Wyman ha spectacular open views. We descended directly down steep slabs in to West Mill Brook, and completed a loop.
The second time was in and out via West Mill. It's the "short" route. That day, we had rain and pea soup fog, zero views, and it was still a great day out.
If you are taking the West Mill approach, you can find Wyman Brook fairly easily. There is a fairly well used camping area along the N shore of West Mill Brook, near where Wyman Brook departs. It's a fairly direct trip up Wyman from there.
