The Camino de Santiago explained

The Camino de Santiago explained: what to know, how it works and how to do it well — clear, practical and up to date.

The Camino de Santiago is not a single trail but a network of historic pilgrim routes across Spain, Portugal and France, all converging on the cathedral of Santiago de Compostela in Galicia. Walked or cycled by everyone from religious pilgrims to secular long-distance hikers, it's one of the most accessible ways into multi-week slow travel precisely because the infrastructure — waymarking, budget accommodation, a built-in sense of community — has been refined over centuries. Here's how the main routes differ, how the credential and Compostela system works, and the practical basics for planning your first Camino.

The main routes, and how they differ

Most first-time walkers choose a two-to-three-week stretch of the Francés or Portugués rather than attempting a full route end to end — the last 100 km into Santiago on any route is the minimum distance to qualify for a Compostela on foot, and a hugely popular choice for those with limited time. If you're a non-EU passport holder combining the Camino with a longer trip across Spain, France and Portugal, keep an eye on your Schengen 90/180-day allowance so the walk itself doesn't push you over it.

The credential and the Compostela

Before setting out, pilgrims obtain a credential (pilgrim passport) — a small folded document collected from a Camino association, a starting-point church, or many albergues — which is then stamped at least twice daily along the route, at albergues, churches, cafés and town halls. This stamped credential is your proof of having walked (or cycled, at double the required minimum distance) the route, and it's checked at the Pilgrim's Office in Santiago to issue the Compostela, the certificate of completion, awarded to anyone who has walked at least the final 100 km or cycled the final 200 km with a properly stamped credential.

Get your credential stamped consistently from day one, even for a short final stretch. The Pilgrim's Office checks for a plausible, consistent pattern of stamps covering your claimed distance, not just a handful from the final days. Missing stamps on early or middle days of even a short walk can complicate getting the Compostela at the end.

Where and how to sleep

The Camino's defining feature is its network of albergues — pilgrim-specific hostels, some municipal and very cheap, others private and slightly more comfortable, almost always requiring a valid, stamped credential to stay. Bunk-style dormitory rooms are standard, particularly on the Francés, and most operate on a first-come basis without advance booking in the traditional style, though this has been changing on the busiest stretches in peak season, where booking a bed a day or so ahead has become more common and sometimes necessary. Private rooms are available in many towns for pilgrims wanting a break from dormitory life, at a higher but still generally modest cost compared with a standard European hotel. If you'd rather ease into multi-day walking before committing to a full Camino, our guide to slow travel for first-timers covers a gentler introduction to the same car-free, unhurried style of trip.

When to walk

Late spring (May–June) and early autumn (September–October) are generally considered the most comfortable windows — avoiding the harshest summer heat on exposed stretches of the Francés and the Via de la Plata, while still offering long daylight hours and open albergues. Midsummer sees the largest crowds and the highest temperatures on the more exposed inland routes; winter walking is possible on lower-altitude coastal routes like the Portugués but many albergues on quieter routes reduce hours or close entirely outside the main season, and the Pyrenees crossing on the Francés can be genuinely hazardous in poor winter weather. See our guide to winter train travel in Europe if you're bookending the walk with rail travel in the colder months.

Getting to and from the trailheads

Most Camino starting points are reachable by train or bus rather than requiring a flight directly to the trailhead. Saint-Jean-Pied-de-Port, the classic Francés starting point, is reached by a scenic branch rail line from Bayonne in France; Porto and Lisbon for the Portugués have their own international airports with good onward rail connections; Irún for the Camino del Norte sits on the main France–Spain coastal rail line. At the other end, Santiago de Compostela has its own airport with connections to major Spanish and some European cities, plus rail connections back into the Spanish network for onward travel — useful if you're continuing to explore Spain afterwards rather than flying straight home. See our broader guide to Iberia overland if you're combining the Camino with more time in Spain and Portugal by train.

Packing and physical preparation

The single most common mistake is carrying too much weight — a pack kept to around 10% of body weight is a widely repeated guideline among experienced pilgrims, since even a well-planned Camino involves consecutive days of 20–25 km on foot, day after day, which punishes an overloaded pack far more than a single day hike would. Proper broken-in walking shoes or boots, moisture-wicking socks, and a realistic pre-trip walking routine of several weeks matter more than any single piece of gear. Blisters, not exhaustion, are the most common reason pilgrims cut a Camino short — treat foot care as seriously as the walking itself from day one.

Frequently asked questions

Do I need to be religious to walk the Camino de Santiago?

No — while it remains an active Catholic pilgrimage route for many, a large proportion of modern walkers do it for entirely secular reasons: the physical challenge, the slow pace, or simply the experience of a long walk with built-in community. The Compostela itself has both a religious and a secular "certificate of distance" version available at the Pilgrim's Office.

How far do I need to walk to get a Compostela?

At least the final 100 km on foot, or the final 200 km by bicycle, with a credential stamped at least twice daily throughout to prove it. Most first-time walkers choose a two-to-three-week stretch well beyond this minimum rather than only the last 100 km.

Do I need to book albergues in advance?

Traditionally no, and many still operate on a first-come basis, but the busiest stretches of the Camino Francés in peak summer season increasingly benefit from booking a day or so ahead. Quieter routes like the Camino del Norte generally still need less advance planning.

Which Camino route is best for a first-timer with two to three weeks?

The Camino Portugués from Porto or a substantial final stretch of the Camino Francés are both popular first choices, offering good infrastructure and manageable daily distances. The Camino del Norte and Via de la Plata suit those wanting a quieter, more physically demanding route on a subsequent Camino.
