Smoo Cave

Highlight • Cave

The river plunges almost 25 meters into the cave. You can also see that from the outside - there is a platform above the cave on the other side of the street. So do not miss it.

Lower Traligill Cave

Highlight • Cave

Lower Traligill Cave is the main sink for the River Traligill from Gleann Dubh. In wet weather the cave overflows and resurges, rapidly flooding the valley below.

The entrance is visible from the Glenbain track, a broad arch with gravel and boulders on the floor.

Stone Cave

Bit of a surprising find this. But probably very useful when the weather is really bad

Waterslide Cave

Highlight • Cave

The large opening reveals a waterslide with a river flowing from a pothole above and leaving through the cavern to the right (where it ends in a sump).

Don't try to enter the cave as the ground is steep and slippery - this is a dangerous place.

Uamh an Tartair Cave

Highlight • Cave

The water can't be seen but it can be heard - the large chamber is a dead-end.

Further progress, strictly for equipped and experienced cavers only is made by crawling to the right under a section of low roof.

a nice spot for a snack break. eneterance is quite low so you might need to take your rucksack off before entering.

Quite a popular little hike, so it's quite busy. The caves aren't really that impressive - apart from their age and the finds, they're quite small - but there's a really strong spring on the way, which basically creates a fairly large stream on the side of the path.

Great caves! They're obviously part of a system that you can descend into when you have experience.

Green shimmering algae on cold stone walls, an underground waterfall, a large chamber that opens onto a bay with a sandy beach - the Smoo Cave is an impressive natural beauty in the north of Scotland.
