Dutchman’s Cap Treshnish Isles, Mull

Information

Dutchman’s Cap

The Treshnish Isles is an uninhabited archipelago of several small islands found off the south west coast of Mull. The islands have been landmarks for travellers through the Hebrides for thousands of years. The names of some of the islands reflect their importance to the Vikings who once ruled in the Hebrides.

In July 2023 the care of The Treshnish Isles passed from The Hebridean Trust charity to The National Trust for Scotland. They are designated a Site of Special Scientific Interest SSI and a Special Protection Area SPA due to their importance for breeding seabirds.

Bac Mor is sometimes referred to as The Dutchman’s Cap due to its shape. The Gaelic name has a couple of possible interpretations. Mor simply means large, but Bac can mean a bank, or also an obstacle or hindrance. The islands profile is possibly the most distinctive of the Scottish Islands as it is like a Mexican sombrero or a Dutchman’s hat.

Volcanic Origins

Bac Mor, like many Scottish islands is of volcanic origin. The peak in the middle of the island is a former volcanic cone. The flat surrounding ground is formed from ancient lava flows. Despite having no safe landing places there are the remains of summer sheilings on the island.

Having sailed past Bac Mor on many occasions the opportunity presented itself to land on the island on what was a totally flat calm sunny weather. The ‘Cap’ stood proud on a blue sea under a blue sky and looked very inviting. We positioned Springtide on the east shore opposite a flat spit of lava that projected out from the sheer cliff edge. On close approach the island is quite clearly weathered lava, black and pitted by hundreds of thousands of years of west coast weather.

Landing on Island

We landed below a gully or split in the cliff face. It was a scramble on all fours to climb up the to grassy plateau. On broaching the plateau, a wonderful open grassland stretched to the north. Beyond that the remainder of the Treshnish isles lay quietly in light blue sea . The pleasure of landing on an un-grazed Scottish island is a delight with thigh deep grass, wild meadow flowers and birds darting from bloom to bloom.

The island is almost devoid of heather with a deep carpet of grasses and some bracken. The breeze was just strong enough to bend the grass over showing its silvery underside. Waves of shiny grass fluttered north pushed on by the puffs of wind coming from the south.

Time was of the essence, so I made a straight line up the steep bank aiming to summit along the north ridge. With the route topping out at the ‘lump’ of rock protruding from the plateau. It was a complete pleasure to make my way up and up towards the top. One last scramble brought me out to the rounded summit that is topped with a concrete indicator and trig point. The views were breath-taking. Coll, Tiree to the west. Iona, Staffa to the south east with the backdrop of Mull to the east. To the north the rest of the Treshnish Islands, west corner of Mull and Ardnamurchan point beyond. Further north  Eigg, Rum and the faint shape of the Cullins on Skye. stood above the blue sea.

Springtide Waiting

My taxi was waiting so after a quick 360 video and a minute to soak up the view I set off back down the steep slope to the gully. The depth of the grass allowed me to throw myself down the slope bouncing on the soft verdant cushion. The trip down took a fraction of the time of the grind up the hill. Once back in the dinghy we paddled very slowly back to the yacht. The visit to the island had been wonderful all the more enjoyable in the glorious Scottish summer weather.

Anchorage

There is no real sheltered anchorage off Lunga. Sheer cliffs or lava flow reefs make any approach in a keel boat quite a challenge. We struck lucky as it was a clam day and we had time to explore. Nick and crew were happy to stand off in Springtide as we explored the island.

We chose what looked like a shelf of lava on the east side. The image below shows the rough position and the gut in the cliffs that allowed me to scramble up to the lush grass plateau.
