Start well
Choose the correct archaeological site and entrance. Consult the official transport page and the current map before choosing a rail station or meeting point.
Use Pompeii’s official map and current opening information. The three observations can fit different permitted routes; a photographed house is not a promise of access.
A visit that fits
Pompeii for All provides an official accessibility itinerary. Read it for the precise route and facilities; do not treat every ancient street as equivalent.
If a house is closed, choose another open space that lets you examine the same question about threshold, room and street. The purpose is to understand a town, not complete a rigid photograph checklist.
