Glen Kinglass, Glen Loin and Argyll Forest Park loop

This loop is considered difficult, bordering on very hard. It's an extremely demanding and lengthy undertaking, requiring excellent fitness and advanced mountain biking skills. Expect significant elevation gain and loss, prolonged climbs, and technical descents. It's likely a multi-day adventure for most riders.

You'll encounter a comprehensive mix of terrains. This includes smooth forest roads, some tarmac, rough and rocky sections, eroded singletrack, and potentially very challenging unridable sections. Particularly in Glen Kinglass, be prepared for rough patches, boggy ground, rocky sections, and multiple river crossings, some of which may require dismounting and pushing or carrying your bike.

Yes, extensive sections of hike-a-bike are highly probable, especially in Glen Kinglass. Parts between Kinglass Lodge and Loch Dossard have been described as unridable due to rutted 4x4 tracks and boggy peat. Some demanding sections within Argyll Forest Park may also necessitate pushing your bike.

Given the length and nature of this loop, there isn't a single designated parking spot for the entire route. You would need to plan your starting point carefully. For sections within Argyll Forest Park, various car parks are available, such as those near Ardgarten. For Glen Loin, parking is often available in Arrochar. For Glen Kinglass, access points might be more remote, potentially requiring logistical planning for shuttle or multi-day parking.

The route offers spectacular scenery and several notable points. You'll get a View of Loch Lomond from Steep Forest Track, stunning vistas of Loch Lomond, and a View of Arrochar and Loch Long. The Argyll Forest Park itself is a highlight, as is the Glen Loin Trail. You'll also experience the challenging Climb to The Rest and Be Thankful.

Yes, dogs are generally allowed on trails within these areas. However, as much of the route passes through remote and wild landscapes, often with livestock, it's crucial to keep dogs under strict control, preferably on a leash, especially during lambing season or near wildlife. Always follow the Scottish Outdoor Access Code.

The best time to ride this challenging loop is typically from late spring to early autumn (May to September). During these months, you'll generally find more stable weather, longer daylight hours, and lower water levels for river crossings. Winter conditions, including snow, ice, and significantly higher water levels, would make this route extremely difficult and potentially impassable.

No specific permits are required for mountain biking this route, nor are there entrance fees for the general access areas within Loch Lomond and The Trossachs National Park. However, always adhere to the Scottish Outdoor Access Code, which promotes responsible access. This includes respecting private land, leaving no trace, and being mindful of wildlife and other users.

Yes, sections of this extensive route overlap with several other named trails. You'll find parts that follow the Ardgartan Peninsula Circuit, the Loch Lomond and Cowal Way, the Cat Craig Loop, the Mary Queen of Scots Way, the Three Lochs Way, the Cobbler Trail, the Glen Loin Loop, and the Old Military Road.

Given the remote and demanding nature of this loop, you should be self-sufficient. Essential gear includes a well-maintained mountain bike, appropriate clothing for all weather conditions (layers are key), a helmet, navigation tools (GPS device with downloaded maps, compass, and physical map), plenty of food and water, a first-aid kit, bike repair tools and spares, and emergency shelter if planning an overnight trip. Due to the remoteness, consider a personal locator beacon (PLB) or satellite messenger.
