Often overlooked compared to its neighbor Cascade, Porter Mountain offers a more rugged and challenging ascent when approached via the Blueberry Mountain Trail from Marcy Field. This route is a true test for those seeking a more adventurous climb, featuring significant elevation gain, rocky scrambles, and some of the most underrated views in the High Peaks.

Special Considerations:
This approach to Porter Mountain is far less traveled than the traditional Cascade route and is significantly more demanding. The trail is often wet, steep, and overgrown in sections, requiring careful footing and strong endurance. The total elevation gain makes it comparable in difficulty to some of the larger High Peaks, such as Giant or Algonquin. Hikers should come prepared with proper gear, adequate water, and a solid understanding of backcountry navigation.
Water Availability:
Limited; a small stream is available at the 1-mile mark
Maximum Grade:
1,200 feet over 0.7 miles leading to Blueberry Mountain
Sunrise or Sunset:
Great for sunrise. Blueberry is a good spot for it
View Type:
Some panoramic views from Blueberry and good views of the Great Range from summit
Keene Valley and Marcy Field
