Bandar Bukit Mahkota is actually a strategic mix-development located in between Bangi and Nilai which can be access from KL-Seremban Highway (If you are heading South, it would be the immediate exit after Bangi and if you are from South, it'd just be after KLIA exit), or the Elite Highway if you are from northern area (which you have to choose the route leading back to KL direction) or via federal road from Bangi.
We would usually be going there over the weekend(s)...just for family-get-together thing!
p.s. I would be filling in more information of this place from time to time whenever I have a free time to update my journal.
