Family friendly, fantastic grooming, consistent product
3 hours from Boston, limited night life
Just returned from a 5 day ski vacation with my family - wife, six year old, and 9 year old. We stayed on mountain at the North Peak condos located just below the North Peak quad lift.
Conditions were excellent and SR did a fantastic job grooming at night. Night skiing is also available, which few skiers take advantage. Those who do will find themselves alone on the mountain.
The only resort in the east of comparable size that I have skied is Killington and I have yet to have a really great ski experience there because of crowds, conditions, and access.
Sunday River, while spread out as a mountain, has made significant improvements in base lodges, lift access, and snowmaking. Nearly all the terrain (with exception to the glades on Oz) were open. Even though it was President's Day, the crowds were still nothing like at Loon or other resorts closer to Boston. With the addition of the Chondola connecting the South Ridge base lodge to the North Peak, SR is postioned to really leverage the North Peak lodge for events, catering, and 4 season access.
A note: the back areas of Oz, Auroa, and Jordan can be really tough for snowboarders as there are a number of flat points between lifts. Skiers can skate but boarders can be left walking, especially on Kansas. That said, the glades of Oz and Aurora (Flying Monkey, Tin Woodsman) rival Jay Peak and Stowe on big powder days.
