When I arrive at this impressive complex, its carpark is filled with tour buses and expensive cars.
A Thai staff member fluent in English leads me to the lobby, with its giant display wall of Monsoon Valley wines, and on through the huge alfresco dining area.
On a wooden balcony, I am seated at my table, beneath a large umbrella, with sweeping views across the vineyard towards the Gulf of Thailand.
Before settling down to have a meal and sample the wines, visitors can ride elephants through the grounds, take guided tours to learn about its viticulture methods or pedal mountain bikes along forest trails.
Built on the site of a former elephant corral, where wild Asian elephants were domesticated, Hua Hin Hills sprawls across almost 200ha in a lush valley.
But I am here to imbibe. So I clutch a generous glass of Cuvee de Siam Rouge, a bold red with notes of cherry and chocolate, which is among Monsoon Valley's most awarded wines.
Then the food arrives and I am enchanted by the delicate tastes and pleasing textures of foie gras terrine, smoked duck breast on crispy wonton and chilled crab meat and apple timbale. Each dish is fresh, unique and succulent.
I chase the food down with a glass of Monsoon Valley's Chenin Blanc Late Harvest, a sweet white wine that is suitably light and refreshing in the sweltering Thai weather.
It may be the effects of the wine or the satisfied afterglow of a fine meal, but I feel like taking up permanent residence on the restaurant balcony.
The meandering elephants, hollering monkeys and glimmering temple in the nearby jungle remind me this is no typical vineyard.
I feel right at home, yet I am so very far from home.
