Carnan Eoin, Dun Meadhonach Fort, Eilean Dubh and Rubha Garbh

This 16 km (10 mile) outing on Colonsay is a varied coastal-and-hill circuit with only modest climbing—about 300 m (985 ft)—but it feels bigger than the numbers suggest because the terrain changes constantly between rough pasture, heather, rocky shoreline, short steeper pulls, and exposed headlands. The overall difficulty sits well in the medium range: there are no major mountain hazards, but the route is remote in places, can be very windy, and sections near the coast demand careful foot placement, especially in wet weather. Colonsay itself is low-lying, with its highest ground reaching only around 143 m (469 ft), yet the open Atlantic setting gives the walk a wild, spacious character. (visitcolonsay.co.uk)

The route is on the Isle of Colonsay in Argyll and Bute, off Scotland’s west coast. The most practical access point for visitors is usually Scalasaig ferry terminal, the island’s main port and settlement, which is the nearest significant landmark for the start area if the exact trailhead is not otherwise specified. Colonsay is reached most commonly by CalMac ferry, with sailings linked to Oban and also shown on the wider Oban–Colonsay–Port Askaig–Kennacraig route information; island visitor information also notes that day trips are sometimes possible from Port Askaig on Islay on certain days.

If travelling by public transport, the usual mainland approach is to reach Oban by train or coach and continue by ferry to Scalasaig. Once on Colonsay, transport is limited: recent community information states there is no bus service on the island, so walkers should plan on using a car, bicycle, local taxi if available, or arranging lifts/accommodation transfers in advance. If driving, bring the car on the ferry if space allows, then use the island’s single-track roads to reach the nearest parking spot for the chosen start. Because ferry capacity and schedules can change, checking the current sailing timetable before committing to the walk is essential. (colonsay.info)

The landscape you move through is one of the most interesting parts of the day. Colonsay combines machair, moorland, low rocky hills, broad sea views, and a coastline broken by inlets, skerries, and small offshore islets. Even though the island is compact, the route links several distinct features: Carnan Eoin, the island’s highest point; Dun Meadhonach Fort, one of the island’s prehistoric defensive sites; Eilean Dubh;
