Why Devon's estuaries are the calmest water in the county

Open coast paddling in Devon asks a lot of you: swell, clapotis around the headlands, and wind that arrives with nothing in the way to slow it down. Estuaries are different. Sheltered by wooded banks and built-up shorelines, they give you flat water on days when the sea outside is uninviting, and they offer something the coast can't — a landscape that changes completely between high and low water.

They also happen to be some of the most sensitive habitats in the South West. Almost every estuary mentioned here is a Site of Special Scientific Interest, and several sit within Special Areas of Conservation or Special Protection Areas. That isn't a reason to stay off the water. It is a reason to know the rules, plan around the tide, and paddle as though you're a guest — because you are.

Read the tide before you read the weather

In Devon, spring tides give you four to five metres of range in most estuaries, occasionally more. Neaps can be less than half that. The difference decides whether you'll be paddling over mudflats or mud.

• The first two hours of the ebb are usually the fastest water, especially in the upper reaches of the Dart, the Teign and the Taw. If you launch on a falling tide, plan to be back before the channel empties.
• Tidal gates matter. Kingsbridge, Totnes and Newton Abbot all sit behind stretches that dry to a trickle, or to nothing, at low water. A kayak can often get through where a boat can't — but not always.
• Wind against tide at an estuary mouth produces short, steep chop that surprises people. If the forecast is force 4 or above and the wind is blowing straight into the ebb, paddle the upper reaches instead.
• Use the rule of twelfths to estimate how much water is left under you, and add a safety margin of half a metre if you're exploring side creeks.

Four estuaries worth a full day

The Yealm is arguably the friendliest estuary in Devon for a first trip. Launch at Newton Ferrers and follow the channel past Noss Mayo, through the moored boats and out towards the mouth, where the water stays flat in anything up to a moderate breeze. It's short — you can paddle the whole navigable length in a couple of hours — but the wooded banks, the heronry and the low-tide sandbars make it feel bigger than it is.

The Dart offers the longest trip. Launch at Steamer Quay in Totnes on a push of flood and ride up towards Sharpham, or start nearer Dartmouth and work the edges of the moorings. Between Totnes and Dittisham the water is generally calm, the banks are steep and green, and there's enough distance to make a proper day of it. Watch the flow through the Dart's narrow bends — it can run faster than you'd expect.

The Exe is the estuary for birdwatchers. From Topsham or the Turf, you can paddle the main channel with wide views across the mudflats, but keep well clear of the reedbeds and roosts on the eastern side. Outside the winter months it's a gentle, spacious paddle with plenty of places to stop on a falling tide.

The Taw and Torridge around Barnstaple, Instow and Appledore offer big skies, shifting sandbanks and genuine tidal planning. The channels move. Follow the buoyage rather than last year's memory of it, and don't cut across a bank on a falling tide.

Access, launching and parking

In England there's a public right of navigation on tidal water, but launching is a different matter. Many slipways are privately maintained or run by a harbour authority, and some charge a small fee or ask you to register. Assume you'll pay, and carry cash.

• Launch from established slipways rather than scrambling over saltmarsh or cordgrass, which is easily damaged and slow to recover.
• Don't launch or land through mooring lines, mooring buoys or shellfish beds.
• Check local harbour notices for speed limits, exclusion zones and any seasonal restrictions.
• Park considerately. Lanes in Newton Ferrers, Ringmore and Dittisham are narrow, and residents have heard every excuse.

Wildlife rules that actually matter

Between October and March, Devon's estuaries fill with overwintering wildfowl and waders — Brent geese, shelduck, curlew, redshank, and avocet on the Exe. These birds burn energy they can't easily replace, and a kayak heading straight for a raft of them can put a whole flock to flight.

• Stay at least 100 metres from rafts of birds, and further if they start lifting their heads or shuffling.
• Don't land on sandbars or islands that hold roosts, even briefly, and even for a photograph.
• Avoid seagrass beds, which occur in the Yealm, around Salcombe and elsewhere. Don't anchor in them or drag a paddle through them.
• Practise check, clean, dry between estuaries to avoid moving invasive species such as wireweed and Pacific oysters.

Kit, weather and a sensible turnaround

Wear a buoyancy aid, always — estuary water in early summer hovers around 15°C and is colder in spring. Carry a phone or VHF in a dry bag, a spare paddle, a towline and a spray deck. Morning fog is common in spring and autumn, so take a compass bearing on your outward leg.

Finally, tell someone where you're launching and when you expect to be back, and give yourself a hard turnaround time based on the tide rather than on how much fun you're having. Devon's estuaries reward patience and preparation — and they'll still be there next weekend.
