Bulgaria is a time warp of old and new--from chic shops in the city to donkey cars in the country. We hike to a mountain monastery in Rila, meet two sculptors (dad does Stalin, son does nudes), and enjoy a traditional dinner feast at a local home.

Whether in the pubs, in its ancient past, in its struggle for independence, or in its lively streets, Dublin is the capital of a nation with a rich history and an irrepressible spirit.

This time we're exploring the far west of Ireland. Starting on the remote Aran Islands, we cruise to Galway, hike the rugged Burren, and marvel at the Cliffs of Moher before venturing to Dingle and finishing on Great Blasket Island.

This time, we're enjoying the charms of Germany's villages and evocative ruins. While much of this country is an urban and industrial powerhouse, this episode is all about storybook Germany.

This time it's quintessential Germany -- and that means Bavaria - fairytale castles, the exciting city of Munich, and fun in the breathtaking Alps.
