This trail might be great if you can find it after a dry spell but it can be quite boggy too. It passes through a really amazing valley which you and any mates you've brought are likely to have to yourself(ves).
If it's boggy, you may have to walk more than ride though. Ride through the boggy sections at your own risk - you never know if you'll sink a few inches into the muck or if the bog will swallow half of your front tire leading to a rather spectacular endo (although any mates you've brought may enjoy that). The scenery is awesome though with large mountains along both sides of the valley and several small lochs.
The trail starts in the small hamlet of Luib. There are a number of farm roads and animal trails that take off at the end of the short road which passes through the hamlet, so a GPS track or the MTB Project mobile app
will be useful. The trail begins on the west side of a small creek.
After you pass by a small loch (Loch nam Madadh Uisge) you'll climb a very low pass (100 ft) into the beautiful Strath Mor valley. A lazy river drains the valley into the Atlantic Ocean. Another creek feeds into the second, larger lochan (Stratha Mhor). The trail passes very close (and at times seemingly through) the western side of the lochan. On the positive side, the bottom of the loch is rocky, so if you have found the trail to be a bogfest, the rocks will prevent your sinking into the lakebed and it may be easier to ride trough the lake than "over" the boggy ground.
After the loch, you'll have to find a place to ford the river as the trail continues on the eastern side of the river. I found a convenient crossing area after a small fenced area at the south end of this lochan.
The trail along the eastern bank is more defined and generally easier going but there still may be some boggy sections. You'll reach a third, much larger loch (Loch na Squabaidh). Again, the trail passes directly along (and at times through) the edge of the loch. Beyond the loch, the trail becomes more manageable and very quickly, you'll reach the B8083 road on the Atlantic Ocean.
