Blue Sage sits on Main Road in Mattituck, on the North Fork side of the Hamptons region. It's classified as a day spa with a moderate price tier, the kind of place suited to a solo afternoon reset or a couples visit rather than an overnight retreat stay.

The schedule runs six days a week. Monday and Tuesday are shorter sessions, open from 10am to 3pm, while Wednesday and Saturday extend to 5pm. Thursday and Friday are the longest days, open from 10am until 7pm. The spa is closed on Sundays.

Access is flexible on paper — walk-ins are welcome — but the listing also notes a reservation requirement, so it's worth calling ahead to confirm whether a specific treatment or time slot needs to be booked in advance. The phone line is (631) 298-4244, and the spa's own site has more detail on current offerings.

Beyond the basics of location, hours, and price tier, there isn't public detail here on specific treatments, packages, or amenities. Anyone deciding whether to drive out to Mattituck for a visit should check the official site or call directly to get a sense of what's on the treatment menu and whether current wait times call for a reservation.
