The Green Grotto Caves have an incredibly rich history, from Indians who once dwelled in this place to the Spanish who used it as a hideout from English invaders. More recent accounts make mention of a nightclub that operated here, and it also featured in the James Bond movie "Live and Let Die."

Damnoen Saduak is Thailand’s most famous floating market, about 80 km southwest of Bangkok. Vendors in wooden boats sell fruit, snacks, and noodles along the canal, while stalls on the banks push souvenirs and crafts. It’s lively, colourful, and very touristy, but it’s still a classic day trip. Most people go with an organised tour, though you can also catch a bus from the Southern Bus Terminal and hire a boat on arrival. Go early in the morning to avoid the thickest crowds and heat.

Ain Zubaidah stands as a testament to ancient engineering, a water system commissioned over 1,200 years ago by Zubaidah, wife of the Abbasid Caliph Harun al-Rashid. Moved by the plight of pilgrims, she ordered the creation of a complex network to channel water from the Al-Kar mountains to the holy sites of Makkah. This 35-kilometre feat of engineering combined underground channels, surface aqueducts, and deep reservoirs, some reaching 40 metres underground, to traverse the arid landscape. Though time has left much of the original structure in fragments, sections have been restored, including a major renovation in the 1920s. The system's scale remains awe-inspiring, with its gentle gradients, 132 inspection chambers, and strategic storage tanks. Today, visitors can explore remnants of the conduits in the foothills around Makkah, a tangible link to a visionary project that sustained generations of pilgrims.
