The tour is entirely in Korean, but as a non-Korean speaker, I still had a great time. Our guide; Kelvin speaks English and was very helpful, sending me a detailed itinerary via WhatsApp so I didn’t miss anything.
Featherdale Wildlife Park was a highlight that is totally worth the trip, getting close to the animals was an unforgettable experience. The guide also helped us to take stunning photos at Lincoln's Rock, definitely will not miss out on any photo op even if you are traveling alone. The sunset spot the guide brought us to was stunning, despite the cloudy sky. We couldn’t do stargazing due to the weather, but the guide took us to see Sydney’s night skyline instead, which was a great alternative.
