The good weather continues. Was a beautiful Sunday in late November, and we decided on the eastern flank of Dunderberg which affords a good vertical ascent as well as several good views. We climbed along the R-D Trail, and passed the Dunderberg Spiral Railway tunnels and then took the hoist path as it is followed by the R-D Trail. Throughout this trail the hike passes and goes along parts of the spiral railway remnants. The Dunderberg Spiral Railway was an ambitious project in the early 20th century which involved building a large hotel atop Dunderberg Mountain, and creating a railway that snakes itself up the mountain. This project was abandoned in the middle, leaving many remnants of its existence throughout this part of the hike.

We took several of the good views, including the Indian Point Nuclear Power Plant, the City of Peekskill, and the Bear Mountain Bridge between Bear Mountain and Anthony's Nose. After a swamp before ascending Bald Mountain, we opted to take one of the railway paths back down to the T-T Trail and then head back from there. We cut across and took the T-T Trail back to our car.
