Sri Mahamariamman Temple is tucked away on Jalan Tun HS Lee, which runs parallel to Chinatown’s Petaling Street. Though hours differ depending on special events, the temple is generally open Sunday through Thursday from 6am to 8:30pm; Friday from 6am to 9:30pm; and Saturday from 6am to 9pm. The temple can be viewed in less than an hour, and is always free to visit, although you may wish to donate a few ringgits towards maintenance. Be sure to dress conservatively and remember to leave your shoes outside.
The temple is easily accessible by metro: take any line that stops at Pasar Seni LRT station, just a three-minute walk away from the destination. Alternatively, you can take a taxi as drivers are quite familiar with this popular location.
