I'll admit I have a slight positive bias towards ERCC, having been a member since I was born, so…read morefor the last 26 years [and counting..]
Ellington Ridge offers a great mix of people from different areas of CT and western MA, and while this is indeed a "country club", the atmosphere is relaxed enough where nobody will jump all over you for failing to rock the full set of Brooks Brothers attire at all times, and your kids are always welcome.
I'll summarize it all as an overview for any potential member scouring Yelp for good country club reviews in the area - -
Tennis - Traditional clay-type surface that you will have to sweep after you use it, but there are never lines to play. I honestly haven't been down in that area for some time now, but I believe there are 3 (maybe 4) courts to use, surrounded by trees so there is always a lot of shade available. There is also a little tennis building (shed-sized) that has A/C and water, mostly utilized during tennis lessons.
Pool - Not quite Olympic sized but pretty close, dedicated areas for laps, and a 10ft deep end/diving board area. The pool itself is well-maintained but was definitely put in some time ago. Concrete(ish) bottom with horizontal tiling to mark lane areas.
Dining - Three dining rooms, one is off the bar (usually frequented by golfers) and one large enough to hold weddings / events. The food has had its ups and downs over the years but is (and has been for at least the last 5+ years) on a significant up, I have yet to consume a bad meal, breakfast, lunch, or dinner, in as long as I can remember.
Golf - Since this is where I spend most of my time, this is where I am most critical. I love the course, the 18 holes are a nice mix of challenging and easy holes, and are consistently updated and maintained so to always be in great condition. The driving range is always in use, and the pro shop has several knowledgeable pros that will help you even without appointment.
There are 3 practice areas in addition to the driving range, two strictly chipping/putting greens and one with sand traps to practice out of. There is a food pavilion off one of the putting greens, usually grilling on the weekends in the spring, summer, and fall.
I'm sure there are some things that I missed, but those are the biggies. Overall, this is a great place to join if you are looking for a club with good food and good golf, with a more "exclusive yet community" feel to it.
