Rome2rio is a dream come true for travelers, whether you’re a research geek or someone that loathes planning. It offers the best, most comprehensive, aggregator for travel itineraries that I have ever used. They provide an all-in-one destination to search for air, train, coach, ferry, mass transit and driving options to and from any location.

You can search for travel destinations around the world: Europe, North America, South America and Asia Pacific. Thousands of transport operators are represented in their database, making it the largest online repository of surface transport routes anywhere online. Flight schedules are pulled for over 670 airlines licensed from OAG Aviation. Data from OpenStreetMap is used to provide driving and walking directions for most countries worldwide.

I truly love this site.
