Wild Brown Trout
Caithness Lochs

From the famous marl lochs to the remote Flow Country peatland waters

⚠️

A word on safety If you are heading out to the remote Flow Country lochs, take a map and compass — mobile signal is unreliable or non-existent across much of this terrain, and GPS alone should not be relied upon. Always wear a life jacket for any boat fishing, and exercise caution when wading: some lochs have rocky, uneven beds and can drop off sharply. Let someone know where you are going and when you expect to return.

⚠️ Important Notes

  • No Sunday fishing on most trout lochs and all salmon rivers in Caithness. Plan your week accordingly.
  • Midges: From June onward, Highland midges can be severe — especially at dawn and dusk in calm weather. A midge head net is essential, not optional.
  • Wind: Caithness is one of the windiest places in the UK. This helps with midges but can make loch boat fishing dangerous. Check forecasts daily.
  • Mobile signal: Poor in many fishing locations. Download offline maps before leaving towns.
  • Scottish Access: Scotland's Land Reform Act gives right of responsible access — but fishing permits are still legally required for most lochs.
  • Ghillie hire: Strongly recommended for first-time visitors, especially on the Thurso. Local knowledge is invaluable.
