Mission Statement: Explore this easily accessible island gem
Trail Introduction
This trail takes you clockwise around the beautiful island of Great Cumbrae on Scotland’s west coast. Discover the stunning sea-life and explore the myriad of beautiful beaches around its coastline where you can stop and have lunch as well as some great opportunities to spot porpoises, basking sharks and lion’s mane jelly fish.
About the Area
The Battle of Largs took place in 1263 between Norway and Scotland. A fleet of 160 Viking vessels moored off the Cumbraes some of which broke loose in a storm, in trying to salvage their vessels a fierce battle ensued.
Millport is home to Britain’s smallest cathedral the Cathedral of the Isles and Garrison House which was used as accommodation for the Officers and Captain of the Royal George, a revenue sailing ship who played a key role pursuing smugglers on The Clyde.
There is an aquarium at FSC Millport where you can get up close and see the local marine life.
The lion’s mane jelly fish is one of the largest known species of jellyfish and can be found in the waters around Cumbrae from May to September. They can grow up to two meters wide. Be careful of them as they can give a nasty sting.
Basking sharks return to Scottish waters from the end of April, feeding on the rich plankton until autumn. They are sometimes spotted in the waters around Cumbrae so keep your eyes peeled.
Porpoises are regularly found in the waters aroud Cumbrae. Smaller than dolphins they can often be seen playing in the waves.
Why not finish the day with a trip to Nardini’s ice cream parlour. Opened in 1935 the parlour is based in a stunning Art Deco building on Largs seafront and with over 32 varieties of ice cream there is a flavour for everyone.
Interesting fact: Legend has it that in AD 710 St Mirin arrived in Cumbrae and rid the island of snakes. The Cathedral of the Isles is believed to have been built on the site where he preached. To this day Cumbrae remains snake free.

- On passing the south peninsular point, the waters open into Millport Bay. There is safe landing at the head of the bay at Millport and sandy beaches where you can stop for lunch.
- On leaving Millport see if you can see the painted Crocodile Rock before heading south, then west past then southern peninsular.
- Start your journey north past Deadman’s Bay and into Fintry Bay. There is a sandy beach here where you can stop for tea and cake at the High Tide Café (& WC’s).
- Keep heading north and watch out for Harbour Porpoises along the way.
- At the top if the island you will find White Bay, a great place to pause and take breath before making the crossing back.
