We came up the Gironde for the tide and stayed for the wine. That is the honest version. The plan had been a quick stop on the way south, but once you have tied up within walking distance of a first-growth estate, the schedule tends to slip. If you sail your own boat, or charter one on the Atlantic coast, the Bordeaux wine country is one of the few world-famous vineyard regions you can actually reach on your own keel.
This is a guide to doing exactly that: which chateaux are realistically reachable from the water, where you put the boat, and how the tide dictates the whole thing.
The estuary sets the rules
Nothing about Bordeaux by boat works without the tide. The Gironde is the largest estuary in western Europe, and the flood runs hard. From the entrance at Pointe de Grave it is a long way up, and you do not fight that current, you ride it. Carry a fair tide and you make easy progress; misjudge it and you crawl.
Pauillac, the heart of the Medoc, sits about 40 km north of Bordeaux on the left bank. The city itself lies another stretch up the Garonne above the confluence of the Garonne and Dordogne. Plan your legs around the flood so you arrive with water under you and the stream behind you, and the whole passage becomes a pleasure rather than a slog. If the estuary itself is new to you, read my account of the run up the Gironde estuary to Bordeaux before you commit to a date, because the timing is the entire game.
Pauillac: tie up among the first growths
If you only do one wine stop by boat, make it Pauillac. The marina La Fayette, built in 1977, holds around 150 boats and sits right in town, with the fishing pontoon and full services including masting and de-masting. The town quay itself offers mooring for about 10 boats with diesel, water, electricity, showers, a 15-tonne crane and a slipway.
What makes Pauillac extraordinary is what surrounds it. The appellation holds 18 Grands Crus Classes, including three of the five Bordeaux first growths: Chateau Lafite Rothschild, Chateau Latour and Chateau Mouton Rothschild. The famous Route des Chateaux, the D2, runs through the appellations from near the town. You step off the boat, walk or hire a bike, and you are among names that fill auction catalogues.
A word of warning that no wine list mentions: book your tastings ahead. The classified estates are working businesses, not drop-in cellars, and the headline names often require an appointment days or weeks in advance. Smaller properties are friendlier to the wandering sailor, and frankly the wine is often the better value.
The city: berthing in Bordeaux itself
Bordeaux is genuinely reachable by boat, which still surprises people. The Port de Plaisance lies on the left bank in the Bassin a flot, a lock-controlled basin a few kilometres from the historic centre. It has 9 pontoons for up to 278 boats, taking lengths under 20 metres and draughts to 2.50 metres, with water, electricity, showers and a haul-out for boats up to 12 metres.
There are also river pontoons along the Garonne run by Bordeaux Metropole. The Cite du Vin pontoon, opened on 1 June 2016, is 94 metres long and 5.5 metres wide, sitting right beneath the wine museum. These quayside berths put you in the city, but they are tidal and exposed to the current, so they suit a short, well-planned visit rather than a casual overnight. Contact the marina office before you arrive, as space is limited and the lock has its own schedule.
From the city you are not in the vineyards, but you are in the trade. Bordeaux made its fortune shipping wine down this river, and the Cite du Vin tells that story far better than I can. It is also a fine base for a day trip out to the estates by car or train.
Reaching Saint-Emilion and the right bank
The Medoc is the left-bank story. For the right bank, the Merlot country of Saint-Emilion and Pomerol, you swing up the Dordogne instead of the Garonne. Saint-Emilion stands on the hillside north of the Dordogne valley, 8 km from the river port of Libourne, with its jurisdiction a UNESCO World Heritage Site since 1999 covering 8 communes and 5,000 hectares of vines.
Libourne is the natural water gateway, and from there it is a short hop ashore to one of the prettiest wine villages in France. I have written that side of the trip up separately in Saint-Emilion and the Gironde from the water, because the Dordogne has its own tidal quirks, including a mascaret tidal bore that runs up the river on big coefficients.
A realistic itinerary
Here is how a relaxed wine week shapes up if you have your own boat or a bareboat charter:
- Enter the Gironde on a rising tide, anchor or berth at Royan to break the journey.
- Carry the flood up to Pauillac, settle into the marina, and spend two days on the Medoc chateaux by bike.
- Continue up the Garonne to Bordeaux, lock into the Bassin a flot or take a river pontoon for a city day.
- Drop back down and turn up the Dordogne for Libourne and Saint-Emilion if time allows.
Distances are deceptive on a river that runs at several knots. Always check the tidal coefficient before each leg, because the Gironde rewards patience and punishes haste in equal measure.
Getting into the estuary in the first place
Before any of the wine, there is the matter of arriving. The Gironde opens to the Atlantic between Pointe de Grave and Pointe de la Coubre, and the entrance bar demands respect in any swell against an ebb tide. Most cruisers stage the trip at Royan, the marina just inside the entrance on the right bank, which makes an ideal launch point for the run up the estuary on the following flood. Royan to Pauillac is a long single tide, so leave early and let the stream do the heavy lifting.
The estuary is buoyed and the main channel well marked, but it is wide, brown and featureless in its lower reaches, and the banks are a long way off. Keep to the channel, watch for the big ships that use the river to reach the port facilities, and do not be tempted to cut corners across the mud. A chartplotter with up-to-date charts earns its keep here, because the sandbanks shift and the water gives you no visual clue what lies beneath it.
One pleasant surprise is how quiet the upper estuary is once the commercial traffic thins. Above the Bec d'Ambes the Garonne narrows, the vineyards creep down toward the water, and you get the sense of arriving somewhere by the same route the wine left for three centuries.
When to come
Spring and early autumn are the sweet spots. The wine harvest, the vendange, falls in September and into October, and arriving in its last weeks means the estates are busy but the country is at its most alive, with pickers in the rows and the first new wine in the air. High summer is hot and the city bakes, while winter brings short days and a sleepy waterfront. May, June and September give you long light, warm afternoons and estates that have time to talk.
Whatever month you pick, build the trip around the tidal coefficients, not the calendar. A neap week with weak streams makes for slow, frustrating legs; a few days either side of springs and the river practically pulls you up to the wine.
What it actually costs
Wine tastings range from free at small properties to 30 euros and well beyond at the classified estates, with the grandest names charging premium prices for a guided cellar visit. Berthing in Pauillac or the Bordeaux marina is modest by Mediterranean standards, a fraction of a Cote d'Azur marina fee in August. The real expense is willpower at the cellar door.
We left the Gironde with a bilge full of bottles we had not budgeted for and a much clearer sense of why this estuary built a city. Reaching the great Bordeaux wine chateaux by boat is not the fastest way to taste them, but it is by some distance the most memorable.
