The World Heritage listed Ajanta caves (Buddhist) were another tight squeeze on the way to a different train station (Jalgaon) for a 24 hour trip to Varanasi.
These cave temples weren’t as cool as the ones in Ellora, but still interesting. I found the cave paintings disappointing, but without a guide (nor a good flashlight – my headlamp isn’t working anymore!) they were rather faint and I couldn’t usually find the specific painting that the guidebook mentioned in a particular cave.
Tip: if you can only do one, see Ellora.
