You can take a songthaew, also known as a baht bus, from Pattaya towards Sattahip and ask the driver to drop you off at Nong Nooch Garden. This is an affordable option but might require some local language skills to communicate with the driver.
Many travel agencies in Pattaya offer half-day or full-day tours to Nong Nooch Tropical Botanical Garden. This option often includes hotel pick-up and drop-off and sometimes a guide to introduce you to all of the garden's features.
If you are renting a car, head south from Pattaya on Sukhumvit Road (Highway 3). Turn left onto the 163 highway following the signs for Nong Nooch Garden. Parking facilities are available on-site.
