Take CW3 from jurong East. CW6 from boon lay. The bus stop for CW6 is not at the interchange. It is along the main road near the interchange. You could ask around when you are there. The fare is sg4 and bus is frequent . Bus travel by 2nd link. www.causewaylink.com.my for details. There is no direct bus from woodlands causeway. I won't recommend that you to take a bus to JB sentral or Larkin and transfer to another bus to Bukit Indah. I tried it once and it took me forever to get to Bukit Indah.
