Ben Starav and Glas Bheinn Mhòr from Loch Etive trail running loop

This loop is considered difficult and is best suited for experienced trail runners. It involves significant ascent, steep and rocky terrain, and some scrambling sections. While parts have decent paths, expect long stretches of rough ground and potentially very boggy areas, especially on lower slopes. It requires very good fitness, sure-footedness, and sturdy footwear.

While Komoot suggests a duration of around 4 hours for jogging, trail research indicates that even experienced walkers might take 8 to 9 hours to complete this challenging route in summer conditions. Trail runners should anticipate a demanding effort, as some sections will require power hiking rather than continuous running.

The terrain is predominantly steep and rocky, with sections requiring simple scrambling. You'll find decent paths along rivers and mountain crests in places, but also significant stretches of rough, steep ground. Be prepared for boggy conditions, particularly on lower slopes and descents, where paths can be very wet.

The trail starts from Loch Etive. Specific parking details are not provided in the tour data, but typically access points for trails in Glen Etive are found along the single-track road that runs alongside the loch. It's advisable to research current parking availability and regulations before your visit, as spaces can be limited.

The route offers absolutely incredible and stunning views, especially on clear days. From the summit of Ben Starav, you'll get sensational vistas of Loch Etive and Ben Cruachan, potentially even Ben Nevis. You'll also encounter fine waterfalls, impressive rock features, and the majestic appearance of Ben Starav itself, rising steeply from the head of Loch Etive.

While specific restrictions for dogs are not mentioned, many trails in the Scottish Highlands are dog-friendly. However, given the challenging terrain, potential for scrambling, and the presence of livestock (especially during lambing season), it's crucial to keep dogs under strict control, preferably on a leash. Ensure your dog is fit enough for a long, strenuous day.

The best time to tackle this challenging route is during the summer months (June to September) when weather conditions are generally more stable, and daylight hours are longer. However, even in summer, be prepared for changeable mountain weather. Avoid winter or early spring unless you have extensive winter mountaineering experience, as conditions can be severe.

Generally, there are no specific permits or entrance fees required for hiking or trail running on public access land in Glen Etive or the wider Scottish Highlands. However, it's important to respect the Scottish Outdoor Access Code, practice Leave No Trace principles, and be aware of any local regulations, especially concerning parking or camping.

The loop includes significant summits such as Ben Starav, which is the highest Munro in the local area, and Glas Bheinn Mhor. You'll also pass by Stob Coire Dheirg. The route is often undertaken as part of a three-Munro circuit, sometimes including Beinn nan Aighenan.

Given the trail's difficulty and remote nature, essential gear includes sturdy trail running shoes with good grip, waterproof and windproof layers, extra warm clothing, a map and compass (and the ability to use them), a fully charged phone, sufficient food and water, a headlamp, and a first-aid kit. Gaiters can be useful for boggy sections.

Glen Etive is quite remote, so options for pubs or cafes directly at the trailhead are limited. You would likely need to drive further afield, perhaps towards Glencoe or Taynuilt, for post-run refreshments and accommodation. It's wise to plan this in advance, as services are not readily available immediately after completing the loop.
