Wonderful hiking experience. Was here in October 2023. As others have noted, trails (if any) are not marked, so a VERY good topo map or GPS is required. If using an app like Gaia or AllTrails, download the maps as there is very minimal cell service. Another hint if you're using an app, make sure you phone is fully charged and turn off your Wi-Fi as this will save battery power (you won't be able to use it within Bisti, anyway).

And, as others have noted, bring plenty of water. Use sunscreen and wear a wide brim hat. Plus a kerchief or Neck Gaiter might be helpful to keep out dust as it does get pretty windy at times.
