Adventure brief
Three Ferries, One Isle: A Day of Coastal Climbs and White‑Sand Lunches from Dunoon
This guided 80 km (50 mi) ride launches from Dunoon and traces quiet coastal roads and rolling Cowal hills before crossing to the Isle of Bute; the route mixes mountain climbs — including the category‑3 Craigendive ascent — with ferry crossings and a lunch stop on the white sands of Ettrick Bay.
Start in Dunoon, on the Cowal Peninsula in western Scotland, and spend a day riding an 80km loop that stitches together quiet coastal lanes, a short category 3 climb, and three ferry crossings that feel like stage transitions. The route begins at Dunoon Victorian Pier and follows Shore Road past Kirn and Sandbank along the Holy Loch with views toward Kilmun and Strone, then swings inland through Glen Lean. The road narrows and opens onto glacially-carved hills and patches of heath, passing standing stones that mark earlier lives before the Craigendive climb - short, steep, and decisive - tests legs and pacing. Descend to Loch Ruel and the Kyles of Bute, where the first ferry from Colintraive to Rhubodach carries riders onto the Isle of Bute.
Bute unfolds with airy coastal flats and quiet villages; the ride tracks the shore to Port Bannatyne and crosses west toward Ettrick Bay. The white sand at Ettrick is a perfect midday reset - picnic ground, windbreak, and sea view - before the group decides whether to press on the island to Mount Stuart or head directly to Rothesay for the ferry. From Rothesay the ferry to Wemyss Bay is cinematic: the coastline of Cowal slips away while the Toward Lighthouse and mountain silhouettes shrink on the horizon.
A final, short ride from Wemyss Bay to Gourock and a ferry back to Dunoon completes the loop. The plan balances climbing and flow: 732 meters of elevation spread over quiet tarmac rewards steady pacing, and three ferry rides add both crossings and recovery. This tour favors riders who are comfortable with roughly 50 miles in a day and confident on mixed road surfaces; groups stay small (maximum 10) for coaching and camaraderie. Bring a road or gravel bike, a compact toolkit, layered weather protection and a willingness to take the salty sea air between long climbs.
What makes this trip special is how the landscape changes in a single day - from sheltered sea lochs and standing stones to island sand and Victorian seaside towns - linked by ferries that are integral to coastal life. It's a practical, scenic primer on Cowal and Bute: local geology of rounded hills and rocky shorelines, marine birdlife and the wide horizon over the Firth. For riders who want a full day that reads like several micro-adventures, this route delivers terrain, culture, and ferryway drama in one loop.
Riders should plan to meet at Dunoon Victorian Pier; minimum age is 14 and groups are capped at ten to keep pace and safety tight. The operator asks you to arrive with tires properly inflated, a charged phone and any snacks you prefer - lunch at Ettrick Bay is pay-as-you-go. Weather on the Firth can turn quickly, so expect variable wind and dress in layers.
