Delfi is a great ride out of Athens and the pavement is excellent the whole way up into the Parnassos Mountains. The site is awesome and the little town of Delfi reminds me of a Swiss village tucked away i the mountains. Also there is a small village called Arahova on the way to Delfi which is much the same with an excellent view down to the Gulf of Corinth. I've stayed several times in Delfi at the Hermes Hotel which has an awesome view of th Gulf. Delfi is a nice place to spend the day. It's one historical site outside Athens that's well organized.
