Yes, you can travel to other Schengen countries with a Malta Tourist Visa. Since Malta is part of the Schengen Area, the visa allows you to move freely between the 27 Schengen countries. You do not need additional visas for each country. However, Malta must be your main destination or the country where you stay the longest. You must also make sure that your total stay in all Schengen countries does not exceed 90 days within 180 days.
