Why climb when you can simply look up?

There is a particular pleasure in arriving at a cathedral city, spotting the tower above the rooftops, and knowing that in half an hour you could be standing at the top of it. Britain's cathedrals offer some of the finest viewpoints in the country, and most of them are gained by nothing more exotic than a spiral staircase and a bit of determination. The reward is a perspective on a medieval city that no postcard can quite capture: the cloister below you, the river threading through the outskirts, and the surrounding countryside laid out like a surveyor's map.

What many visitors do not realise is how varied these climbs are. Some towers take twenty minutes at a gentle pace; others demand a proper hour of steady work. Understanding that difference before you set off is the single best way to enjoy the day.

Know the stairs before you meet them

Cathedral towers are medieval buildings at heart, and their staircases were never designed for visitors in walking boots. Expect tight, winding stone steps cut for smaller feet, worn into shallow hollows by centuries of use, and often rising in dim light. In places the passage narrows to shoulder width, and there may be a low lintel or two to duck beneath.

Many towers now operate a one-way system, with a separate descent stair or a timed slot for each group. Where the route is single-track, you may need to wait in a recessed alcove while others come down. Handrails are usually present but not always continuous, and some sections open onto a parapet walk with a chest-high wall and nothing beyond it but air.

Step counts vary enormously. York Minster's central tower runs to around 275 steps, Lincoln's central tower to roughly 271, and Durham's to about 325. St Paul's in London is the marathon of the genre, with 528 steps to the Golden Gallery, though you can stop at the Whispering Gallery if that is enough for one day. Salisbury's spire, the tallest in Britain at 123 metres, involves a little over 300 steps. Treat any published figure as a rough guide, not a contract.

Stamina, pace, and the art of the pause

You do not need to be an athlete, but you do need to be honest with yourself. The climb is continuous, often in a confined space with limited airflow, and the effort of turning as you rise uses more energy than a straight staircase. If you can manage several flights at home without needing to stop, you will almost certainly manage a cathedral tower.

The trick is to walk at a conversational pace and pause deliberately rather than waiting until you are gasping. Most towers have a landing or two where you can stand aside, catch your breath, and let others pass. Use them. Guides would far rather you take an extra five minutes than arrive at the top dizzy and miserable.

• Start slow. The first fifty steps set the tone for the whole climb.
• Breathe steadily. Winding stairs make it easy to hold your breath without noticing.
• Step aside to rest. Never stop in the middle of a narrow flight where others are following.
• Drink water before you start, not during the climb, when hands are needed for rails.

The best times to attempt the ascent

Mornings are generally kinder. The stone is cool, the light through the lancet windows is at its best, and the first tour groups have not yet filled the narrow sections. Aim for the first or second slot after opening if you can.

Weather matters more than you might think. Clear, dry days give the long views you came for, but they also bring the crowds. A day with high cloud and good visibility is ideal — you get the panorama without the queue. Avoid climbing in strong wind, since exposed parapets and galleries can be uncomfortably gusty, and some towers close their highest levels in poor conditions. Rain makes stone steps genuinely slippery, and ice is a firm no.

Seasonally, late spring and early autumn strike the best balance: comfortable temperatures, manageable queues, and long daylight hours. Midsummer afternoons can be stifling inside a stone shaft that has been absorbing sun all day.

Bells, weather, and other things that shape your day

One factor often overlooked is bell ringing. Towers used for Sunday service ringing, practice nights, or peals can be off limits to visitors, or require you to pass the ringing chamber at a moment when the ringers are mid-method and not to be disturbed. If you have your heart set on a particular tower, check its opening pattern before you travel — several cathedrals restrict tower access to guided tours only, and these may run just a few times a day.

It is also worth noting that climbing is not permitted in every cathedral. Some have no public tower access at all, while others allow it only with a verger or volunteer guide. A short enquiry at the welcome desk, or a glance at the cathedral's own visitor information, will save you a wasted journey.

Etiquette, kit, and a few towers to put on your list

Dress as you would for a decent country walk: flat, grippy shoes, layers you can shed, and nothing loose that might catch. Large rucksacks are usually refused or must be left below, so travel light. Carry only what fits in a small bag, keep your hands free for rails, and bear in mind that many towers have no lift and no accessible alternative once you begin.

Be patient with others. Children, slower walkers, and anyone nervous about heights deserve the same courtesy you would want. Keep voices low near ringing chambers and services, and never lean over parapets for a photograph.

If you are building a list, York, Lincoln, Durham, Norwich, Ely, Worcester, and Salisbury all offer memorable ascents, while St Paul's remains the great urban classic. Each has its own character — some austere and echoing, others bright with twentieth-century glass. Climb two or three in a season and you will start to notice how differently architects solved the same problem of getting people up, and keeping them safe, above a city.
