Start on water that is barely moving

Flowing water is deceptively powerful. A river that looks glassy and unhurried can carry you a kilometre in twenty minutes and pin you against a fallen willow before you have worked out how to steer. That is why every beginner's first session belongs on still water: a canal basin, a sheltered lake, a pond-sized backwater, or a broad, slow reach of a lowland river with no current worth mentioning.

Save the downriver trip for your third or fourth session. The order that works is: flat, enclosed water first; then a short out-and-back on gentle current; then a one-way downstream run with a shuttle arranged. Skipping steps is how people end up swimming in cold water with a board still attached to their ankle.

Reading the current before you launch

Stand on the bank and watch for two minutes. Look for bubbles, floating leaves or drifting twigs — anything moving tells you speed and direction. If you cannot paddle upstream against it at a comfortable walking pace, it is too fast for your first river day.

Then look for the hazards that catch beginners:

• Weirs and sluices. Never paddle towards one to "have a look". Portage around it, well upstream of the lip.
• Strainers. Fallen trees, overhanging branches, reed beds and debris. Water flows through them; you will not. Aim for the clear channel.
• Shallows and riffles. Ankle-deep water is a fin-snapper and a trip hazard. Read the surface texture — choppy lines usually mean shallow.
• Bridges and pilings. Water accelerates around piers and forms eddies that can push you sideways.

Check the river level too. Rain falling twenty miles upstream will reach you hours later. If levels are rising, or heavy rain is forecast, choose another day. Water below about 12°C takes your breath away on contact, and UK rivers are cold for most of the year.

Access, permissions and where to get in

In England and Wales, only a fraction of rivers has a clear public right of navigation. In practice, most paddling happens on stretches where navigation rights or licences exist — many waterways are covered by a permit from the navigation authority, and joining a local club is the quickest way to learn which stretches are straightforward.

Look for:

• Public slipways and country parks with parking close to the bank.
• Canal towpaths — the calmest possible introduction, with a shallow edge and easy exits.
• Designated launch points marked on local guides or club maps.

Never launch across private land or through a garden, and avoid fishing beats during the coarse season. Park so you are not blocking a gate or a passing place, and check whether you need a permit before you unload. On a one-way run, sort the shuttle first — leave a car at the get-out and walk the bank to confirm the exit is usable.

Wear a buoyancy aid — and dress for the water

A buoyancy aid is not optional on a river. Choose one rated to at least 50N and fitted so it does not ride up over your ears when you float. Test it in shallow water: float on your back and check you can breathe easily. A board leash carries a real snag risk in moving water; if you wear one, use a quick-release waist leash and know exactly how to release it, or leave it off altogether.

Dress for immersion, not for the forecast. A wetsuit, or a drysuit in cold conditions, plus a windproof layer. Avoid loose cords, dangling jewellery and anything that can trap. Keep phone, keys and a warm layer in a dry bag strapped to the board, and tell someone your route and expected finish time.

Practise falling before you go anywhere

Falling in is not a failure; it is the skill you need most. Do it deliberately in waist-deep water near the bank:

• Fall flat, face forward or on your back, arms wide. Do not reach for the bank with a straight arm.
• Let go of the paddle if you need to. It floats.
• Float on your back, feet up and pointing downstream if there is any flow. Never try to stand up in moving water — feet can wedge between rocks.
• Then get back on. Swim to the middle of the board, grab the handle, kick hard and slide your hips onto the deck, then bring your knees up one at a time.

Repeat this until it is boring. Boring is exactly what you want when it happens for real.

Your first downstream run

Keep it short — two to three miles is plenty — on a wide, slow stretch with easy banks. Start upstream of your finish, paddle on your knees for the first ten minutes, and stand up only when you feel settled. Stay on the inside of bends, where the water runs slower. Give anglers, moored boats and swimmers plenty of room and slow your paddle right down as you pass.

Stop before you are tired. Cold, fatigue and a dropping river level make poor companions. Pack out everything you brought, leave the bank as you found it, and take a moment at the get-out to note what you would do differently next time. Then go again — the second trip is always calmer than the first.
