Recommendations for vacation this fall!?

My friend are looking to take about a week long (7-10 days) trip ton an international destination. We traveled around central and southern Ireland last year and had an absolute blast, so we are looking for something along the same lines. In more or less words we would like a travel experience where we can enjoy some outdoor adventures/activities (biking, hiking), cultural sights, and some enjoyable nightlife. Obviously places that are close enough to warrant a 7-10 day trip or won't break the budget.

Right now we are considering Spain or possibly Germany and the surrounding smaller countries. We have both already been to Mexico, London, Ireland, and Paris, so those are out of the question, and I promised my boyfriend I would save trips to Italy and Greece with him.

Any suggestions and recommendations you can make would be greatly appreciated!

Thanks in advanced!
