Hope you find the info useful.
Just below Kylesku bridge can be enjoyable, deep water and good for spinning for pollack, don’t know about beach casting but it certainly looks good water.
On the road from Lochinver to Ullapool, there is a good mark for pollack at Rhue lighthouse which is approximately 4–miles out of Ullapool heading north, plenty of car parking and an easy walk to the lighthouse and fishing areas.
If you want try around Lochinver, take the single-track road to Drumbeg there are some beaches worth trying from the rocks Achmelvich, Clachtoll and Stoer.
Stoer beach is just past Clachtoll heading towards Drumbeg can be productive on a rising tide and is safe to fish and easily accessible. Park the car at the cemetery and cross the road, access the machair via the gate and it’s about 100yds to the beach, rocky marks which will then be on your right can be explored with a spinning or a bass rod.
The water looks extremely fishy around Stoer lighthouse but is very dangerous. If you park at the lighthouse and walk to the edge of the cliffs, there is a bay to your left about 0.5mile from the car park that holds pollack and coalfish, but do be careful and pick your days, this area is more for spinning.
An area known as Balchladich which is near Stoer lighthouse has rocks for spinning on your left as you look at sea from the beach.
The beach at Culkein Stoer is very rocky and shallow and beachcasting or spinning will facilitate for a major loss of tackle here, it is also not very productive. Car parking can be difficult but is available if you speak to the locals. If you walk along the track keeping the sea on your right past the pier and the ruined building on your left, then leave the beach/headland and go up hill, you’ll find rocky outcrops as you head to the ‘Old Man of Stoer’ which again hold pollock and coalfish.
Clashnessie, on the road to Drumbeg which is easily accessed, park in the parking bay but this is also a bus turning point, therefore park in the area closest to the village. If you walk with the beach/sea on your left you will come across rocks that provide for pollock and coalfish.
You won’t find many people beachcasting in this area as the locals that fish will spin, most of the good marks are further north and I don’t have much info on them.
There is an an easterly 30-35mph wind forecast and providing a wind-chill of -2 to -5 for the week so be careful on the rocks.
