Archaeological sites are my least favourite among the WHS. Simply because a whole where the found something important still remains a whole, as usually they remove all they find from the site and stuff it into a museum. Nevertheless I drove 2.5 hours from Penang to visit the site (mostly because I got the opportunity to tick one off the list the almost nobody saw so far). The highlight of this site seems to be the museum which shows the importance of this place. It's ok, but not a big deal. Further, the Perak man is not even there, but in KL. Despite the museum, there is not much to see. You can admire a few stones and a nice view over the beautiful valley, that's it. I really hope they will upgrade the accessibility of the site, but I highly doubt this will be a highlight on the list for fellow enthusiasts.
