Coming September 22, 2017. It’s almost fall, and it’s time to think about planning a leaf-peeping trip! Check out the 3-day trip REI Outessa Retreat at the Waterville Valley Resort. Located in the White Mountain National Forest, there will be no shortage of color in this eastern New Hampshire area known for its bright fall foliage. Designed just for women, enjoy tons of outdoor activities like hiking, mountain biking, yoga, paddle boarding and kayaking. The Fancy Camp lodging option is filled, but you can still bring your tent or arrange for resort lodging.
