Polonnaruwa is Sri Lanka's second ancient capital, and it's the real deal. Unlike Anuradhapura's scattered ruins, this city is compact and walkable — you can cycle through the entire archaeological park in a day. The stonework is insane: giant Buddhas, intricate carvings, and a man-made sea that still holds water 800 years later.
The heat is no joke. You'll be biking under a relentless sun, so start at 7 AM and take breaks in the shade. Most guesthouses rent bicycles for cheap, and the flat terrain makes it easy. Food options are basic — think rice and curry or kottu — but the homestay dinners are where the magic happens.
Spend one full day on the ruins, then use the second day to explore the surrounding countryside. Take a boat ride on the Parakrama Samudra, visit the nearby Somawathiya Stupa, or just chill at your guesthouse. Polonnaruwa is best done slow — rush it and you'll miss the vibe.
