• Tackle & Baits

  No access rule appears in what we hold. No slipway, car park or made path shows up nearby in mapping, so treat access as rough. Trout here take small spinners, spoons and, where fly water allows, a nymph or dry. Check whether a boat is allowed before you tow one. Keep proof of licence with you rather than in the car. Stillwater Reservoir at 0.9 miles is the sensible second choice. Signs at Little Causeway Lake carry more weight than any list.
