Java's centre of spiritual learning for centuries, Yogyakarta is a hub of Indonesian art, culture and cuisine. But while most make a beeline for the pristine palace here, this STEP walking tour takes you off the beaten path to discover Kauman – an Islamic village where you'll visit a local market, try tea fit for a king and learn all the secrets of this Javanese gem.With an expert guide by your side, you'll set off to navigate the narrow streets. These tight alleyways were deliberately designed for only two people to pass at a time, helping avoid disturbances to those engaged in solemn worship.See the pagoda-style 17th-century Gede Mosque – the centre of Muslim prayer – and stroll through the stalls of Kauman's marketplace. Browse the trinkets, treasures and farm-fresh produce on offer before taking a tea break with the locals. This is no ordinary brew though, this is Sultan's Tea – the blend of choice for the long list of sultans that have ruled the region since the 1700s.
