Sacred Monkey Forest. A temple forest with about a thousand long-tailed macaques. Entry around Rp 80,000 ($4.50). The monkeys are bold — no food in bags, no loose sunglasses. An hour is enough.
Tegallalang rice terraces. The stepped, palm-lined terraces from every Bali reel. Go at 7-8am for soft light and no crowds. Entry and small "donation" gates add up to Rp 25,000-50,000 ($1.50-$3). The famous jungle swings cost Rp 150,000-400,000 ($8-$22) extra — fun, but purely for photos.
Campuhan Ridge Walk. A free, easy 2-km ridge path over green valleys, starting near the town centre. Do it at sunrise; it is fully exposed and hot after 9am.
Tirta Empul water temple. Bali's holy spring temple, where Hindus bathe in the purification pools. Entry about Rp 75,000 ($4), sarong included. Go early — tour buses arrive from mid-morning.
A waterfall stop. Tegenungan is the closest and busiest; Tibumana and Kanto Lampo are smaller and prettier. Entry Rp 20,000-50,000 ($1-$3) each. Pick one, go early, carry a change of clothes.
Ubud Palace and the Art Market. Both sit on the main crossroads in town. The palace is small and free; the market across the road sells sarongs, baskets and paintings — bargain to about half the first price. Evening legong dance shows at the palace cost around Rp 100,000 ($5.50).
Ayung River rafting. A 2-hour white-water run through jungle gorges — mild rapids, fine for beginners and kids above about 7. Around Rp 400,000-550,000 ($22-$30) per person with lunch.
