Cyprian Keyes plays to a slope of 136 from the black tees. That is higher than the Rees Jones course at Pinehills and higher than anything in MetroWest. It sits in Boylston, an hour west of Boston, and green fees run roughly $44 to $79 before you add a cart. It is the hardest golf you can buy for that money in central Massachusetts.
Mark Mungeam designed it, working out of the Cornish and Silva office, and it opened in 1997 on 230 acres at 284 East Temple St. Par 72, 6,871 yards from the tips, 74.4 rating. There's also a real 9-hole par 3 on the property: 1,230 yards, par 27, around $31.
What it plays like
Target golf on a hillside. Almost every hole moves up or down, and several par 4s dogleg hard with the fairway running out around 220 yards. Pick the wrong club off the tee and you're in the underbrush, not the rough. One reviewer in July 2026 put it directly: bring extra balls.
The greens are the good news. Bent grass, fast, and they roll true. Layout scores 4.2 across 92 reviews and the elevation changes get named as the reason. You never get a flat lie or an obvious yardage, which is exactly what a repeat player wants and exactly what a casual group hates.
It is not a walking course. Reviewers who tried say it can be done and that the hills are steep enough to regret it. Take the cart.
Conditions swing with the winter. Spring 2026 reviews flagged damaged tee boxes and a rough first green after a hard winter, from a golfer who has played there since opening day and rated it well in prior seasons. By midsummer the ratings recovered. If you're booking in April, temper expectations.
The pace problem
Pace of play scores 3.7 out of 5, the lowest of any category on the course. Amenities score 3.6. Those are the two soft spots in an otherwise strong profile, and they show up in the same reviews that praise the layout.
The math is against them. A 136-slope target course with blind shots and elevation change puts a lot of golfers in trouble, and trouble is slow. Book early in the day if pace matters to you. The 4.2 conditions score and 4.5 friendliness score suggest the staff isn't the issue.
What it costs and how to book
Green fees have been tracked in the $44 to $79 range depending on day and time, with GolfNow listing from $62. Online rates are greens fee only. Carts get rented at the golf shop when you check in, so the number you see when booking is not the number you pay.
The booking window is short: five days in advance. Public tee times go through EZLinks at cypriankeyes.ezlinks.com, and members book on separate portals with earlier access. The pro shop line is (508) 869-9999.
The course also runs a Noteefy alert tool that texts or emails you when a slot opens in a window you specify. That exists because the five-day sheet fills and the course knows it.
Clubs are available to rent, but every player needs their own bag on the championship course. No spectators. No strollers on either course. Collared shirts, no denim, no athletic gear. The season runs mid-March to the first real snow.
Who it's for
Single-digit and mid-handicap players who want a hard course and don't mind an hour in the car. If you're chasing slope, this belongs on the list next to Red Tail in Devens and the rest of the hardest public courses near Boston.
Wrong course for a beginner, a big social group, or anyone who wants to walk. For forgiving golf in the same corridor, Juniper Hill in Northborough is 15 minutes away and $54 to walk 18 on a weekday. The rest of the corridor is in the MetroWest guide.
Cyprian Keyes is a five-day booking window on a course good enough that the sheet fills inside it, and the club had to build a waitlist alert tool to cope. Text Carl the day you want to play. He watches the EZLinks sheet, checks GolfNow for the leftover inventory the course dumps there, and calls the shop when nothing is posted, so an hour's drive doesn't end at a full tee sheet.
