This attraction is not large and 30 minutes is enough to visit it. The biggest attractions are the 4,000-year-old quarry and the world's largest obelisk from 3,500 years ago. Walk from the Nile River to the unfinished obelisk less than 20 minutes, but the Google navigation route is wrong ❌. The place you finally walked to is a residential area. The ticket office is on the main road near the museum. You can refer to my markings on the Google map, or you can use Google Map to search the location coordinates 📍24°04’38.8”N 32°53‘39.7“E📍 This is the specific location of the ticket office. I hope it helps you. More travel information, please check my YouTube channel @ivanstrips
