Use the LY identifiers to prepare
Lyon's catalog uses LY identifiers. Open a mosaic's page to check its points, installation information and recorded status, then add the ones that interest you to your plans. The list preserves older entries too, so the total is not the number you can necessarily flash today.
Keep the walk practical
Lyon's rivers and hills make a short distance on a map different from a short walk. Group your targets in one area and use pedestrian directions to check crossings and climbs before linking distant mosaics. Allow time to look up and recognize each piece.
Turn the list into a personal hunt
Open Lyon in InvaderHunter and check your city access. An imported collection helps you focus on missing mosaics; recorded statuses help you decide which stops to keep. Use FlashInvaders to validate your flashes during the walk.
