The greatest local site is actually 20km west of Ruteng near the village of Cancar. The legendary Spiderweb Rice Fields are vast creations that are shaped exactly as their name implies. The surrounding region is beautifully lush with paddies.
For the best view, stop at a small house (drivers all know this place), tip the genial owners about 10,000Rp, borrow a walking stick and ascend a dirt path to a ridge where the surreal shapes of the rice fields can be fully appreciated.
