Simple answer is Yes, - but your journey might be costly and tiring, you do not say where you live or how many will be travelling.
Our jouney two adults from Scotland involved train from Edinburgh to London to Paris via ferry, Overnight Paris to French/Spanish early morning to Girona Local train to Blanes then bus to your destination.
We did not have the Eurostar in those days which would make part of it easier.
Did not say it was easy but it was always worth while. Ex British Rail free travel all the way to French border half price in Spain.
Replying to your post has brought back some great and happy memories when we were 20 years younger.
