I did the Whiteface/Passaconway loop today. It was quite enjoyable. The Blueberry Ledges trail is neat because it travels through some nice clearings (one had a 5' snowman in it!) and it is gradual until the last mile or so. There is a tricky icy ledge near the South Summit right now. Kinda fun to navigate, actually. The views South off of Whiteface are awesome. I could see all kinds of lakes, including Winnipesaukee.
The trip across the ridge was pleasant with lots of openings to view the Sleepers, Osceolas and Tripyramids.
Passaconway is a highly underrated mountain. There is a wooded summit, but the view from just below the summit (as well as just past the summit) is spectacular. You can see over half of the White Mountain 4000'ers from there. I could count 25, but if I had binoculars, I might have been able to pick out Bond, Bondcliff, South Twin and North Twin from a clump of snowcapped peaks behind Carrigain and the Hancocks. The Dicey's Mill trail was beautiful and I would do it again in a heartbeat. The trip is worth the view and then some!
