Actually, WP Travel plugin is translation ready. So, you can translate strings provided in the WP Travel plugin using LOCO Translate plugin. But the strings that are used in tabs cannot be translated using LOCO Translate plugin as the strings for tab are editable and not hardcoded. So, you have to add a translated string for the tab manually.

If you have enabled ‘Use Global Tabs Layout‘ option in the trip as shown in the screenshot below then you have to add translated string for the tab by going to Admin Panel > WP Travel > Settings > Tabs

enable global tabs layout

Also, if you have disabled ‘Use Global Tabs Layout‘ option in the trip as shown in the screenshot below then you have to add translated string for the tab by going to Admin Panel > WP Travel > Settings > Tabs
