3. FABRICA DO CHOCOLATE, PORTUGAL

Willy Wonka himself would approve of this whimsical hotel-museum dedicated to all things sweet. The decor alone is enough to give you a sugar rush: chocolate paint dripping from the ceiling, lollipop-shaped doors – even “golden ticket” headboards. Enjoy chocolate facials, a museum exhibition on cocoa (€8), deliciously scented toiletries and a chocolate fountain at breakfast.

4. LE BRISTOL, PARIS

This grand dame has a Nutcracker-esque chocolate factory on its premises, where production is overseen by the renowned chocolatier Johan Giacchetti. The grand cru cocoas used by his team of chefs hail from Madagascar, the Caribbean and beyond. Mendiants – chocolate discs dusted with praline – are the signature offering and star attraction. Guests can enjoy a special tour of the factory (free) or pick up a box of limitededition sweets (€40).

5. ROSAS & XOCOLATE, MEXICO

A chocolate wonderland housed in a 19th-century colonial mansion on the Yucatan peninsula.

This boutique hotel is best known for its “xocolatherapies”, ranging from a warm chocolate facial to a rose oil foot massage where the recipient enjoys a scoop of chocolate ice cream; it’s nothing but the best here – only 100 per cent pure cacao is used. Unwind with a chocolate martini after your treatment to complete the sensory journey.
