Passport, Visa and Health Information

Requirements vary by nationality and may change at short notice. Approximate visa processing times are included below. Please ensure you review this information before confirming your booking.

Whether you are travelling from the UK to another country, visiting the UK for a walking holiday, or travelling between two overseas destinations, it is important to understand the entry requirements, visa rules and health formalities that may apply to your journey. The information below provides an overview to assist your planning.

For UK Based Walkers Travelling Abroad

Passport and visa requirements vary by destination. Many countries require passports to be valid for at least three to six months beyond your return date. Visitors of certain nationalities may need a visa to enter some destinations.

If a visa is required, standard processing times typically range from two to six weeks, although these times can vary depending on the country and season.

Entry requirements can also include health guidelines, vaccination rules or local regulations. For the most current information, please visit the UK government’s Foreign Travel Advice page.

For Guests Travelling to the United Kingdom

If you are visiting the UK for a walking holiday, your passport must be valid for the duration of your stay. Some nationalities may require longer validity.

Depending on your nationality, you may need either a Standard Visitor Visa or an Electronic Travel Authorisation (ETA). The ETA is an online entry permit for eligible visa exempt travellers and is being introduced in stages for different countries.

Standard Visitor Visas typically take three to six weeks to obtain. ETA approval is usually quicker and may be issued within minutes or days.

To check whether you need a visa or ETA and how to apply, please visit the UK government’s guidance on entering the UK.

For Travellers Heading to Other International Destinations

If you are travelling from one overseas country to another for your walking holiday, passport validity rules, visa requirements and health formalities will depend on the destination and on your nationality.

Please check the travel advice issued by your own government for the most up to date and reliable information. This will help you prepare for any entry requirements, health regulations or local safety guidance that may apply.

Health Requirements

Some countries may require proof of vaccination or have specific health formalities. The UK currently has no mandatory health requirements for entry. Requirements can change at short notice, so please check the latest advice from your government and from the authorities of your destination.
