We were there late in the season after coming down the Rideau. It was a week's wait until a good weather window opened to cross to Oswego, but Kingston and this marina worked out very well. Since it was late, there was plenty of room for berthing. All the marina's shoreside amenities were very good indeed, with clean bathrooms and showers, and new washers and driers. Kingston is a nice city with plenty of restaurants and shopping. Note: it is very exposed to wind from the north, east, and south. We were pinned pretty hard to our facing dock for several days, though when our day to leave approached we were able to maneuver off. Perhaps the lesson is if you can't get off your dock due to high winds, it's probably better to stay put. All in all a good stay.
If there were a stereotypical Canadian resort, this would be it. Sometimes we boaters use the word 'rustic' as a codeword to mean rundown to some degree. But saying that Montebello is rustic is a compliment of the highest order. It is beautiful from bow to stern. The log construction is unique, and the hotel lobby is jawdropping. The marina is quite good though maneuvering requires a small bit of a steady hand. It's shaped oddly, though there was no trace of a current. (The layout is different every season.) The meals in the restaurant are very pricey but stupendous. This is a 5-star resort with all kinds of things to do. You name it, it's got it. Don't let it intimidate you. It's worth it.
Don't be intimidated by the closeness of the slips and thoroughfares as they appear in overhead photos. The transient docks are right at the entrance next to the marina office and fuel dock. And the slips are very big and roomy, perfect for our 45' boat or bigger. Nice shoreside amenities (pool, laundry, bathhouses) and the staff (all Québécois) are delightful. And Valleyfield is amazing! You walk just a couple of blocks and you are right in the middle of a French water-side town with restaurants, bistros, shops and other attractions. There is provisioning (Metro grocery store) if you have a bike or some other transportation. There is also a grocery store called Vincents. A visit to La Petite Grange is a requirement.
Creg Quay is a handy marina along the St Lawrence Seaway that really isn't set up to take big boats (36'+) but we were shoehorned in aok. Even though it is in Ontario (barely) it is used mostly by French Canadians and French is the dominant language spoken there, though English is strong. The people were lovely and very happy (and quite inebriated). We arrived there over the U.S. Labor Day weekend and everyone was in party mode. I swear on my mother's grave, at one point someone turned up a sound system and played YMCA, and everyone started dancing. Hilarious! Shoreside facilities were okay, not great, but very acceptable.
The marina is attached to a large-ish hotel in A-Bay. The docks are fixed and very substantial. They were also high enough to accommodate the higher waters on the lake in 2019. Oddly enough, the only damage they sustained by said high waters is that their outdoor pool was damaged, but they do have an indoor pool that is fine. Perhaps the best feature of the marina is its view; its directly across the SLSW from Heart Island and Boldt Castle. ) Hint: there are free docks at the mansion for you to tie up to to tour the island, but they are first come first serve and not overnight. Also, if you are needing any services such as pumpout or fuel, they are available in A-Bay but call ahead to see if they are open. The high waters are expected back in 2020. Also, note that they do not respond to VHF, or at least we could never raise them.
A fine small marina in a nice town. Good floating docks (and with the rising waters of the lakes, a good feature for sure.) We're a 45'boat and had no problems with fitting in slips, thoroughfare width, whatever. Clayton is a nice town. The only downside is that provisioning isn't really available.
We spent six weeks there in 2019 and thoroughly enjoyed it. There is plenty of water to maneuver in. The transient dock is a long facing dock on the west side of the basin. No worries. The staff is terrific. The shoreside attractions and services are very pleasant. It's a busy place though. If you want someplace quiet and serene, this is probably not it. But it is the best marina on the south shore of Lake Ontario. The only demerit is that it's quite a hike from the transient dock to the clubhouse. We're going back in 2020.
Capri Marina was a very nice stay. Well managed and operated. It's a great big-boat marina with big slips and ample thoroughfares. The dock crew is good. It is very well maintained. It is also very easy to get to NYC from there. The only reason it does not get a five star rating from me is that the bathrooms are not air-conditioned, and they need to be cleaned better. Those are the only things that get a demerit from me. We enjoyed our stay there and would definitely go back there again.
Big slips and thoroughfares make getting in and out easy. Nice amenities. Great store. Miniature golf was fun.
