I hiked over from Whiteface and I liked it much better that way. The views from Whiteface made up for the lack thereof on Passaconaway. The distance between the two peaks in decieving and took me a little under 2 hours on my own. The peak itself is not very well marked and is very disappointing since it is heavily wooded and the only views are from small outlooks on the way up. But the loop to the peak and down is pretty nice. I found it much easier to go down via Dicey's and not via Walden since Walden is very steep and stair like (i.e. not too much fun for me).
I have been told that it's a fun hike in the winter. Definately try and do Whiteface at the same time if you hike it during the spring/summer/fall so you can get some good views in.
Hiked up to the top in a light rain/heavy fog so I hadn't any views. But I would gladly return again and explore the original growth forest. It was very beautiful
I hiked Passaconaway today with White face. Passaconaway has a wooded summit, but makes a nice loop hike with Whiteface. The colors were amazing! Great fall hike!
