Preparing for the Via Francigena: Credential, Best Season, Ferry, Apps & Challenges
Everything you need to know before taking your first step at Canterbury Cathedral: how to get the Pilgrim Credential, when to cross the Swiss Alps snow-free, which ferry company takes foot passengers across the Channel, and how to conquer the 3 toughest stretches of the trail.
Planning a three-month thru-hike across four countries requires tying up several logistical loose ends before leaving home. Unlike trails where you can improvise at any time of year, the Via Francigena has two major geographical bottlenecks: the 2,473-meter Great St. Bernard Pass in the Swiss Alps and the English Channel ferry crossing between Dover and Calais.
1. The Official Pilgrim Credential (Passport) & the Testimonium
The official Credential of the European Association of the Via Francigena Ways (AEVF) is much more than a souvenir booklet for collecting stamps from parishes, abbeys, and town halls; it is the mandatory document that identifies you as a pilgrim so you can stay in donation-based parish hostels across France and Italy, qualify for discounted hiker rates at Swiss campsites, and get transport discounts (such as 10% off Trenitalia regional trains).
🪪 Where to Buy the Credential
If you start at Kilometer Zero, you can buy it right at the Visitor Centre of Canterbury Cathedral (I paid £8.50 / ~€10, where they also give you your first official stamp). You can also order it online ahead of time from the official AEVF website or pick it up at authorized points in Lausanne, Aosta, Pavia, Lucca, or Siena.
📜 The Testimonium at the Vatican
Upon reaching St. Peter’s Square in Rome, presenting your stamped Credential (you must walk at least the final 100 km from Viterbo or Montefiascone, or cycle 200 km) entitles you to receive the official Testimonium parchment inside St. Peter’s Basilica.
2. When to Start: The Ideal Calendar for a Full Thru-Hike
If you plan to walk the entire 2,200 kilometers over 98 to 101 days, you should pick your start date in England by calculating when your feet will reach the Swiss Alps:
| Section / Sector | Best Weather Window | My Real Timeline (June to September) | Off-Season Risks |
|---|---|---|---|
| 🇬🇧🇫🇷 UK & Northern France | May to September | Started mid-June (June 13). Long daylight hours until 10:00 PM made wild camping easy. | In winter and early spring, deep mud across Picardy farm tracks and damp cold are punishing. |
| 🇨🇭 Switzerland & Great St. Bernard (2,473 m) | Mid-June to Late September | Crossed in late July and early August. Snow-free alpine trails and clear mountain weather. | Critical: From October to early June, the pass is buried under deep snow with high avalanche risk. |
| 🇮🇹 Po Valley & Northern Italy | May – June or September – October | Crossed in August. Intense heat and humidity across the Piedmont and Lombardy rice paddies. | In July and August, you must start walking at dawn (5:30 – 6:00 AM) to beat heatstroke and mosquitoes. |
| 🇮🇹🇻🇦 Tuscany & Lazio to Rome | April – June or September – November | Crossed in September (reached Rome on Sept 29). Milder temperatures and golden light in Val d’Orcia. | In mid-July or August, the shadeless gravel roads of Val d’Orcia easily exceed 38 °C (100 °F). |
3. How to Cross the English Channel (Dover to Calais) as a Foot Passenger
One of the most confusing moments at the start of the Via Francigena is walking into the port of Dover only to discover that most ferries only accept vehicles. Keep this in mind so you don’t get stranded at the terminal:
- The only ferry line for Foot Passengers: Currently, P&O Ferries is the only operator that allows foot passengers without a car or bicycle on the Dover → Calais route, and only on specific daily sailings (a port shuttle bus takes you from the terminal building onto the ship).
- Price and booking: On my trip I paid £23 (~€26.97). Make sure to book your Foot Passenger ticket online at least 24 to 48 hours ahead once you know which day you will walk into Dover.
4. The 3 Biggest Physical & Mental Challenges on the Via Francigena
While you won’t encounter brown bears or packs of shepherd dogs like in the Carpathians, three very real challenges cause many thru-hikers to quit every year:
1. The Service Desert & Solitude of Northern France
Between Arras, Laon, Reims, and Langres, you will walk 30 to 35+ km stages across endless farm tracks without passing a single open café, shop, or bakery—and often without seeing another pilgrim for days. Solution: Always carry 1 to 2 days of bread, cheese, and cured meat from the last supermarket, and refill your water bottles at French municipal cemetery taps.
2. The Climb to 2,473 Meters at Great St. Bernard Pass
Climbing from Martigny through Orsières and Bourg-Saint-Pierre up to the Great St. Bernard Hospice takes you into true high-alpine terrain. The air gets thin, you gain over 840 vertical meters in a single short stage, and temperatures can plummet even in August. Solution: Check the alpine forecast the night before, start early in the morning, and keep your thermal mid-layer and rain shell accessible.
3. Heat, Asphalt & Mosquitoes Across the Po Valley Plains
After descending from the Alps into the flat plains around Vercelli, Mortara, and Pavia, the terrain turns pancake-flat between flooded rice fields. The combination of shadeless sun, high humidity, and clouds of mosquitoes tests everyone’s patience. Solution: Start walking at first light to finish your stage before 1:00 PM and buy pharmacy-grade mosquito repellent.
Although the white-and-red waymarks with the yellow pilgrim are excellent across Italy, in northern France and along forest variants it is easy to miss a turn if you only rely on painted arrows:
- Official “Via Francigena” App (AEVF): Free, works offline, and displays both the official stage-by-stage GPS route and the updated directory of parish hostels and water fountains.
- GPX Tracks on a GPS Watch + Offline Phone Maps: Wearing the GPX route on your wrist (I used the Amazfit T-Rex 3) saves you from pulling out your phone in the rain at every junction and preserves phone battery for emergencies and filming.
- Multi-currency expense tracking: Remember to install TravelSpend (use code COPILOTONOMADA for 50% off Premium) to track your daily spending across British Pounds, Euros, and Swiss Francs.
🏥 Travel Insurance & Mountain Rescue (United Kingdom & Switzerland)
Keep two critical details in mind when crossing these four borders: the United Kingdom is no longer part of the European Union, and in Switzerland mountain rescue operations (such as on the climb up to the 2,473-meter Great St. Bernard Pass) are not 100% covered by standard European health cards, where a single helicopter evacuation costs thousands of Swiss Francs.
