Your 'Visit' page uses a custom template.
The Visit Page Template's title and intro text is edited directly in the Content Editor (the window that looks like this). Any text added to the Visit Page Template will appear at the top.
To edit the Paso Robles Tasting Room and San Simeon Tasting Room sections, edit the Visit: Paso Robles and Visit: San Simeon content blocks.
The Visit template also includes a slider/photo gallery. To add and remove photos (slides) to this gallery, create and/or delete new Visit Paso Robles and San Simeon Gallery content blocks.
