Weekend in Sidoarjo

The central town square, a large open space with fountains and shady trees. Locals gather here in the evenings to stroll and kids play on the paved area.

Tip: Come just before sunset. The street food vendors set up around 5pm – try the local tahu petis or es campur. Avoid midday as it's baking hot.

A working market selling fresh produce, spices, and local snacks. It's messy, loud, and genuine – no tourist gloss. Great for watching daily life.

Tip: Head to the dried fish section and look for bandeng presto – Sidoarjo's famous pressure-cooked milkfish. Buy some to take away. Haggle a little, but keep it friendly.

A protected mangrove forest with a wooden boardwalk winding through the trees. You'll see crabs, mudskippers and birds. Quiet and flat, easy walking.

Tip: Bring insect repellent. Go at low tide to see more wildlife. There's a small donation box at the entrance – give 5,000 IDR if you can. No food stalls, bring water.

The ongoing mudflow disaster site, active since 2006. You can view the vast, steaming mudfield from a designated viewing platform. It's surreal and sobering.

Tip: Go early morning before the heat kicks in. Bring a mask as the sulphur smell can be strong. Best viewed from the main road side, not the gated entrances.

A modest science museum with interactive exhibits about physics, biology and local technology. Good for families – simple but engaging hands-on stuff.

Tip: Entry is about 10,000 IDR (less than 1 USD). Visit on weekdays when it's near empty. Don't expect English labels – just play with the levers and buttons.
