We visited Evora during our recent (June 2024) trip to Portugal, and we tried to look at the Megaliths Cromlech. Big mistake. The dirt road leading there was in a terrible shape, and the park with the Megaliths was fenced off and closed. According to the signs they were doing a soil restoration project. The copy of Rick's tourbook that we used was clearly outdated about this site (talks about a "well mantained dirt road").
On the positive side, the cork forest surrounding the area was interesting to see.
