Embark on a moderate hike from Blackwaterfoot to King's Cave, a route that blends coastal scenery with ancient history on the Isle of Arran. This 6.7-mile (10.8 km) trail, with an elevation gain of 649 feet (198 metres), typically takes around 2 hours and 59 minutes to complete. You will experience varied terrain, starting along the shore from Blackwaterfoot, passing below the impressive columnar basalt cliffs of The Doon.

As you progress, the route climbs through woodlands, offering spectacular coastal views towards the mainland and Kintyre, alongside opportunities for spotting local wildlife like shags and oystercatchers. You will also encounter views over moorlands and unique geological formations.

Planning your visit, be aware that some parts of the coastal path can be rocky, and paths on The Doon summit may be faint and overgrown, especially in summer. Sure-footedness is important due to uneven paths and bouldery sections. While some sections, like those through the golf course, offer easier walking, the overall moderate rating reflects the varied terrain and potential for steeper descents. The trail is generally accessible, but always check local conditions before you go.

This trail is notable for its rich historical and natural features.

This moderate 9.5-mile (15.3 km) loop involves a total elevation gain of 1424 feet (434 metres) and typically takes around 4 hours and 28 minutes to complete. You'll traverse beautiful forests, including a notable initial climb to the unique Library in the Woods, a charming log cabin nestled by the Eas Mor waterfall. While some sections are well-kept, be prepared for steep descents and potentially boggy paths, especially around Loch Garbad, making hiking boots essential. The varied landscape truly earns Arran its nickname, "Scotland in Miniature."

To best enjoy this moderate hike, ensure you have good fitness levels and wear appropriate hiking boots, as some sections can be wet underfoot. The trail involves a steady uphill climb to the Glenashdale Falls, with a particularly steep part just before reaching them. While the research doesn't specify trailhead access or parking, planning your visit to the Isle of Arran will likely involve ferry travel. Always check local conditions before you set out, especially concerning weather and trail maintenance.

What truly sets this loop apart are its distinctive landmarks, blending natural beauty with historical intrigue and quirky charm. You'll discover the Eas Mor Library, a hidden gem where you can browse books and leave messages in a secluded log cabin by the impressive 103-foot Eas Mor waterfall.

Embark on a moderate hike along the Kildonan to Lagg section of the Arran Coastal Way, a diverse route spanning 10.2 miles (16.5 km) with an elevation gain of 187 feet (57 metres). This journey typically takes around 4 hours and 12 minutes to complete. You'll experience a mix of unpaved paths, rocky shorelines, and sandy beaches, offering stunning coastal views. From Kildonan Beach, you can enjoy spellbinding vistas of the islands of Pladda, with its lighthouse, and Ailsa Craig, a distinctive volcanic plug. Be prepared for sections that involve scrambling over boulders and potentially muddy terrain, especially after rain. You may also encounter cattle in some fields along the way.

Before you set out, it is crucial to check tide times, as certain sections of the trail, particularly around Bennan Head, can become impassable at high tide. A signed diversion route is available if needed, or you can choose to follow the road inland to avoid the rocky shore. Similarly, at Kildonan, you have the option to continue along the coast or head inland on forestry tracks. This ensures you can tailor your hike to current conditions and your preferred challenge level.

This section of the Arran Coastal Way is rich in geological wonders and wildlife. You'll observe striking black basalt dykes extending into the sea, formed from ancient volcanic activity, and the Kildonan shore is considered one of the best examples of a "dyke swarm" globally. Keep an eye out for seals basking on rocks and the chance to spot otters in the area. The route also passes Torrylin Cairn, the remains of an ancient chambered cairn, adding a touch of history to your coastal adventure.

There are a number of quite big caves, the biggest being Kings Cave with it's ornate ironwork at the entrance. There is evidence of human occupation and activity going back thousands of years.

If attempting to hike towards Glenashdale Falls - Left of loch, a lot of deforestation & uprooted trees blocking visibility/pathway. Unable to find much of a path without roughly following app but had to abandon once a path leading to Whiting Bay/Kildonan. Forest area was extremely soft moss/boggy. Don’t attempt besides enjoying the spot at the picnic part by the loch.

The last 500m to the Black Cave you have to climb over scree, you need good shoes and surefootedness! At the end you walk along the rock face, really not for a "walk"!

When it rains, the rain unfolds its mystical aura. Crossing the stream is also quite slippery. The rest of the path along the lake is also quite adventurous.

July 8: the trip went through a swamp. You can't get through without wet feet. Because everything is green, it is not visible where you can walk and where there are ditches. You fall through everything.
