Arafah is clearly marked by boundary signs; the critical mistake to avoid is standing in the Valley of Uranah, which borders Arafah but is outside its boundaries and does not count.
The plain of Arafah is located approximately 20 km southeast of Mekkah. It is a large, open area that is clearly demarcated by the Saudi authorities with prominent boundary signs in Arabic, English, and other languages. These signs are placed along roads and pathways entering the Arafah area, making it generally straightforward to identify whether you are within the boundaries.
The most critical boundary to be aware of is the Valley of Uranah, which lies on the western edge of Arafah closer to Mekkah. The valley looks similar to the rest of the Arafah plain, and some jamaah haji mistakenly stand there thinking they are in Arafah. Standing in Uranah does NOT count as standing in Arafah, and a jamaah haji who spends the entire Wuquf time in Uranah has missed the pillar of Haji. Nabi (shallallahu alaihi wa sallam) specifically warned: 'All of Arafah is a standing place, except the Valley of Uranah.'
Masjid al-Namirah, where the Haji sermon is delivered, straddles the Arafah-Uranah boundary. The front part of the masjid (including where the imam stands for the sermon) is technically in Uranah, while the back portion extends into Arafah. After the sermon and combined Dhuhr-Asr shalat, jamaah haji should move to the back of the masjid or outside into the Arafah plain to ensure they are within bounds. The Mount of Mercy (Jabal al-Rahmah) is within Arafah. Use GPS-enabled apps like IhramOS to verify your position relative to the boundaries.
