Καλησπέρα και συγνώμη για την καθυστέρηση. Το εισιτήριο είναι στα 8 ευρώ γενική είσοδος και καλύπτει κεντρικό αρχαιολογικό χώρο, μουσείο και αρχαίο ωδείο πέρα από την Αραπόπορτα . Παιδιά μικρά και εκπαιδευτικοί με κάρτα εισόδου σε αρχαιολογικούς χώρους, δωρεάν.

not sure how much in USD- but we paid 2 euros.

The opening times ar rather unpredictable. There dont seem to be any guides either- it's all very low budget in those terms. I went there and discovered it was closed so I jumped over the fence, which the local kids all do all the time! It's not a huge area where the mosaics are and you can easily just wander around, or self guide. No signs though saying what is what. You'll need a pamphlet for that. Or Wikipedia? The wider area also include an amphitheater and a long stretch of wall, as well a a well or washing area. There's no public transport so I hope you have your own. If you are travelling around the area, then take in the national park( see my comment on Google maps app) and follow the waterside tracks, full of little natural wonders such as caves and tortoise habitats.
