Perhaps something more affordable, Aussie Maeve O'Meara offers one-day meanderings mainly around her hometown of Sydney - check out the Indulgence Safari, for those with a sweet tooth (me! me!).

Maeve also organises week long gourmet safaris to various Australian and International destinations (like Greece, Bali and Vietnam) AND if you want to indulge in more, like shop, spa and stuff yourself, there's her Gorgeous Safari where you will be pampered by massages, facials, shopping and feasting. Now THAT's a safari! :)

I came across this site, Gourmet Safari, which organises culinary tours to Italy, France, Spain and Morocco. Imagine cooking in a farmhouse in Tuscany, drinking wine in Provence, having an authentic paella in Spain and tasting the delights of Morocco.

Going on this would definitely be a dream come true and I'm going to add this to my list of Dream Journeys ....
