First time we climbed up this pass, we stopped, took a U-turn, went down and up again! It's like riding on a roller-coaster! The tarmac is also great, which is not usual in Greece, allowing you to scrape your foot-pegs on every turn. It's twisty but it's fast and it's quite safe, as there's almost no traffic, just keep in mind that at the end of the tarmac there's usually a cliff, so definitely there's no space for mistakes!
