I am planning on visiting Delphi this October and I'm hoping to visit the Corycian Cave. I've been able to find mention of it in various guides but the details seem a little sketchy. I've read that the trek up to the cave is about 4 hours, and that's a bit too much for me as a first time solo traveler with little hiking experience. So is it possible to hire a taxi to take me up as close to the cave as possible and hike the rest? Also is the Castalian Spring still off-limits? Any information would be helpful, thanks!
