Big question around Boston is whether Blue Hills Reservation in Milton will offer skiing this winter. Concerns over liability insurance and snowmaking water have thrown the future of Blue Hills Ski Area into uncertainty. Wachusett Mountain in Princeton has an array of Century Pass deals in place – Bronze, Silver, and Gold – with prices lowest now and going up in stages Sept. 14 and Oct. 30. The Bronze Pass is lowest-priced, now at $209 or $199 with a group of four or more skiers, and is good for skiing non-holiday weekdays, and all nights.
