The name honours Cayetano Valdés y Flores, who first saw this coast in 1791 as a lieutenant serving under Alessandro Malaspina aboard the Descubierta. He came back the following year in command of the Mexicana, exploring these waters alongside Dionisio Alcalá Galiano in the Sutil - two tiny vessels probing a labyrinth of channels, and encountering George Vancouver's much larger expedition doing the same thing at the same time. The island did not actually get Valdés's name until 1859, when Captain George Henry Richards, surveying the coast aboard HMS Plumper, assigned it. Richards named an enormous number of features on this coast, and he had a habit of honouring the Spanish who had preceded him - which is why a Gulf Island carries the name of a Spaniard applied by an Englishman sixty-seven years after the fact.

A third of Valdes Island is held as three reserves belonging to the Lyackson First Nation, a Hul'q'umi'num'-speaking Coast Salish community. At Shingle Point, where one of those reserves sits, archaeologists have documented roughly sixty sites, with evidence of people living here going back at least five thousand years. That is the record of a home, not a stopover - generations of families working a coastline that outsiders find forbidding, because they knew exactly where the landings and the resources were. The Lyackson today are a small nation, fewer than two hundred members, and most now live at Chemainus on Vancouver Island rather than on the island itself. It is a common pattern on this coast and a costly one: a community whose territory remains theirs while daily life happens somewhere with a road, a school, and a clinic.

Along the north shore, winter storms have spent thousands of years working on soft sedimentary rock, and the result is extraordinary. The formations known as the Sandstone Galleries are a honeycombed, wind- and wave-sculpted wall of hollows, overhangs, ribs, and small caves - the most dramatic sandstone on a chain of islands already known for it. There is no way to see them properly from land, and no anchorage to speak of. You come by kayak, paddling close under the cliffs on a calm day, reading the shapes as the light moves across them. Orcas are abundant in the surrounding water, which means the trip occasionally offers more than geology.

For an island with so little settlement, Valdes has two well-known places to sleep, and they differ sharply. Wakes Cove, at the southern end near Porlier Pass, is protected water with hiking trails and effectively no facilities - the most notable human trace is an abandoned well on an overgrown road, which tells its own story about how long somebody once tried to stay. The cove takes its name from Baldwin Wake, a retired British naval captain who bought land here in 1876. Blackberry Point, by contrast, is a proper marine campsite: defined cooking and tenting areas, trails leading up from the beach, and a composting toilet. Between the two, a paddler crossing Porlier Pass from Galiano has somewhere to aim for at either standard of comfort.

Everything on Valdes is shaped by what happens at its southern tip. Porlier Pass separates the island from Galiano to the southeast, and like all the Gulf Island passes it funnels the enormous tidal exchange between the Strait of Georgia and the sheltered waters inside - which means ripping current, standing waves, and a brief window each cycle when a small boat can go through comfortably. That pass is why this stretch of coast was a travel route for millennia, why the island's one workable beach sits where it does, and why the modern kayaking and boating trade that keeps Valdes on people's itineraries is a matter of timing above all. Read the tables right and the island opens. Read them wrong and you wait.
