Bonaid Odhar Cave, more popularly known as Dun Bonnets Cave, is one of the Scottish Highlands’ most fascinating hidden gems. Tucked away around a mile from the beautiful Falls of Foyers, this remote cave is notoriously difficult to find but those who seek it out are rewarded with one of the most remarkable Jacobite stories in Scotland.
The Story of James Fraser, the Real Dun Bonnet
After the Jacobites were defeated at the Battle of Culloden in 1746, James Fraser, 9th of Foyers, Chief of the Fraser Clan, went into hiding. A massive manhunt swept the Highlands, but Fraser found refuge in a small, concealed cave near Foyers. It is in this cave he hid for seven long years! Loyal locals risked their lives to secretly bring him food, water, and even beer, carefully timing their visits to avoid detection by Redcoats.
To protect him the locals of Foyers, gave him the nickname “Dun Bonnet.” Donn (or dun) means “brown” in Gaelic, and a bonnet was the traditional Scottish wool cap. This clever alias allowed locals to speak about him openly, right under the noses of the Red Coat soldiers.
The story is not without its darker moments. A young boy delivering beer was captured by the Redcoats and, refusing to reveal Fraser’s location, had his hands cut off. This place is still remembered locally as “The Cask’s Leap.”
On another occasion, Fraser shot a pursuing Redcoat following a servant girl bringing him supplies and buried him in the nearby field. Despite these close calls, Fraser was never discovered in his cave, remaining hidden for seven long years.
Dun Bonnet and Outlander: History Meets Fiction
Fans searching for Outlander locations near Inverness will recognise this story. In Season 3 of Outlander, Jamie Fraser goes into hiding in a cave after Culloden, becomes known as “the Dun Bonnet,” and relies on loyal locals for supplies while avoiding British soldiers.
This storyline mirrors the real-life experiences of James Fraser:
- He hid in a cave for many years.
- Locals secretly brought him food and supplies.
- He was hunted by British troops.
- He remained isolated yet resilient.
Even the scene where young Fergus has his hands cut off echoes the story of the boy punished for taking beer to the cave for Fraser.
How to Find Dun Bonnets Cave
- Park at Falls of Foyers car park (there are toilets and a cafe here), come out and turn left and walk up the hill.
- Take the second right turn, pass a few houses, and cross a small bridge. From here, the Upper Falls are visible. Their flow varies dramatically depending on rainfall, gentle one week, roaring the next.
- Continue along the path and through some trees until the trail forks. Bear left and follow it to a stone wall. Turn right and follow the stone wall, keeping the field on your left. This is where Fraser buried a Redcoat.
- When the wall meets a fence and you see large rocks on your right, turn right and carefully scramble over the rocks to find Dun Bonnets Cave. This part will require a bit of patience as the cave is well hidden in the rocks.
The walk takes around 30–40 minutes but may take longer while searching for the entrance – which is all part of the adventure.
Inside the Cave: Size, History, and Views
You will reach the back entrance first. It’s quite high up so we decided to follow the rock round to the right and locate the front entrance to the cave. The front entrance is narrow but lower down than the back entrance, careful manoeuvring is needed to get inside. We found it easiest to put our feet in first and manoeuvre ourselves inside. The cave once had a second level, but that has long since collapsed. Standing inside, it’s easy to imagine James Fraser scanning the fields for Redcoats. The trees were smaller then, allowing clear views. Today, the woodland is tall and overgrown, obscuring much of the outlook.
The cave stretches roughly 14 metres in length and varies between about 1 metre and 4 metres wide. We entered through the front opening and made our way to the back exit. A tight squeeze to get inside (not a cave to explore if you are claustrophobic). Even just seeing the cave from the outside makes for a fun adventure!
Important Safety Information
Dun Bonnets Cave is a wild, unmarked location. The final approach involves uneven ground and a rock scramble, which can be slippery:
- Wear sturdy walking boots with good grip.
- Avoid the scramble in wet or icy conditions.
- Take care near steep drops and loose rocks.
- Not suitable for those with limited mobility.
- No facilities beyond the Falls of Foyers car park.
Please note: since we last entered the cave we have been informed there’s been some movement in the rocks so we don’t advise entering the cave! It is safer to view it from the outside!
Final Thoughts: Experiencing Dun Bonnets Cave
As with many hidden Highland sites, visit at your own risk. Respect the land, leave no trace, and remember its historical significance.
Visiting Dun Bonnets Cave is as much an adventure as it is a history lesson. Its hidden location is exactly why James Fraser chose it nearly 300 years ago, if it were easy to find, it wouldn’t have been a good hiding place for the Jacobite. Standing inside the cave today, you can feel the courage, tension, and determination that kept Fraser alive.
