Knockan Crag National Nature Reserve
Knockan Crag is a short geology stop on the A835 north of Ullapool. The open-sided Rock Room explains how the surrounding mountains formed, and three trails let you choose between a quick look at the rocks and a steeper walk with views across Assynt.

Our family take
A good break in the drive for primary-age children who are curious about rocks and mountains. Start at the Rock Room, where the displays explain how older rocks ended up above younger ones. You can take the easier Quarry Trail or spend longer climbing towards the Moine Thrust and crag-top views.
- With toddlers. Keep the visit short near the Rock Room, or bring a carrier for the higher trails. The ramped approach does not make the whole reserve buggy-friendly.
- In poor weather. The hillside is exposed and the Rock Room is open-sided. Save the steep climb for good weather; this is not an indoor rainy-day backup.
The practical details
Plan your visit
- Cost and parking
- Reserve access is free. Parking payments are voluntary under NatureScot’s Invitation to Pay scheme; check the suggested tariff on arrival. Blue Badge holders park free.
- Opening and access
- The reserve and unmanned Rock Room are open all day, year-round. Check for temporary access changes before travelling, especially after rough weather.
- Where to go
- Use the reserve map pin on the A835, 21km north of Ullapool. The nearest postcode, IV27 4HH, points to Elphin about 4.5km farther north.
- Toilets
- Toilets in the car park are open 24 hours with level access. The accessible toilet has a RADAR lock, so bring your key if you need it.
- Buggy access
- A low-gradient ramp avoids the steps to the Rock Room. The higher trails climb the crag and include rocky steps; use a carrier if you want to go farther.
- Food and changing
- Bring food, drinks and changing kit. There are two picnic tables near the car park, one with space for a wheelchair or buggy. Check with NatureScot if you need baby changing or food service.

Make it work for your family
Choose your walk
Start with the short trail from the car park to the Rock Room. The low-gradient ramp avoids the steps; from the Rock Room, choose one of the three waymarked trails.
- Quarry Trail · about 20 minutes
- The easier option, doubling back before the climb to the Moine Thrust. A useful choice for a short family stop.
- Thrust Trail · about 30 minutes
- Takes you to the spot where geologists Peach and Horne solved the puzzle of older rocks lying above younger ones.
- Crag Top Trail · about 1 hour
- A circular route with a few steep climbs past the Moine Thrust and views across Coigach and Assynt. Best saved for good weather and confident walkers.

Buggies and mobility
Plan around the car park, toilets, picnic tables and ramped approach to the Rock Room if your family needs an easier visit. One picnic table has space for a wheelchair or buggy, and there are stone seats at intervals along the trails.
The ramp is a way past the steps to the Rock Room, not a promise of smooth access around the reserve. The higher paths climb onto the crag and include rocky steps. Contact NatureScot before travelling if your visit depends on a particular route or accessible facility.

Weather and before you go
Bring waterproofs, layers and shoes suited to rocky paths. In strong wind, heavy rain or poor visibility, skip the crag-top climb and consider a more sheltered stop. Keep children close around slopes and viewpoints.
After severe weather, rock falls and water erosion can affect the reserve. It closes during rock-stabilisation works, so check current visitor information before setting off.

Fit it into an Assynt day
Knockan Crag works as a short break on the drive north from Ullapool towards Loch Assynt or Lochinver. Little Assynt is a useful alternative for families wanting an easier path-based walk; Ardvreck Castle and Loch Assynt can fit the onward route.
Little Assynt Compare an easier path-based Assynt stop.Kylesku Bridge is farther along the road north. Smoo Cave belongs to a wider road trip, while Corrieshalloch Gorge makes more sense on the approach to Ullapool than as a nearby add-on.
