Applecross to Ullapool
The longest of the five stages, and the one where the coast road's habit of following every inlet instead of cutting across them really shows — the direct distance is a fraction of what you actually drive.
Retracing the Bealach, or the low road
Leaving Applecross, most drivers retrace the Bealach na Bà back to Tornapress rather than continue the single-track coastal road south to Kishorn, since the coastal option adds distance without adding much the Bealach hasn't already shown you. From Tornapress, the route follows Loch Carron's northern shore back through Lochcarron village and up towards Kinlochewe, then turns for Gairloch.
Gairloch and the beaches
Gairloch has a run of genuine sandy beaches unusual for this coastline — Big Sand and the beach at Gairloch itself both get properly warm in summer sun despite the latitude, and the Gairloch Museum's exhibits on crofting and the Am Faire lookout give useful context for the empty-looking landscape you've been driving through. It's also the last town-sized services stop before Ullapool, worth using as such.
Inverewe Garden
Just north of Poolewe, Inverewe is a 20-hectare garden built from what was originally bare coastal moorland, sheltered by a planted pine windbreak and warmed by the North Atlantic Drift enough to grow rhododendrons, palms, and other plants that have no business surviving this far north — it sits at roughly the same latitude as Juneau, Alaska, or Central Siberia. It's a National Trust for Scotland property with an entry fee for non-members; budget an hour and a half if you actually want to walk it rather than glance at the entrance beds.
The long run to Ullapool
North of Poolewe the road turns properly remote — Dundonnell and the foot of An Teallach (a serrated ridge as dramatic as anything in Torridon, with far fewer roadside viewpoints signed for it) come before the final descent into Ullapool along Loch Broom. This stretch has some of the sparser fuel coverage on the whole route; see the driving notes page for the specific gap.
Ullapool
Ullapool is a genuine working fishing port as well as the west coast's main tourist town and the ferry terminal for Stornoway on Lewis — it has more restaurants, fuel stations, and accommodation in one place than anywhere else on stages 1–3 combined, which makes it the natural place to break the trip for a night regardless of exactly where your "stage 2" ends.
