Walk the beach, relax at a beach club or swim; great way to unwind and watch an early sunset. Public access usually open all day; beach clubs have specific hours (often 10:00–18:00).
Full-morning boat/snorkel tour visiting Manta rays (seasonal but frequent) and clear-water snorkeling at Crystal Bay and other sites — why to see: superb underwater visibility and big marine life.
Short island drive or scooter ride to scenic cliffs at Devil's Tear and/or a calm mangrove boat tour; most sites open during daylight hours (until ~5:00pm).
Early pickup for a 2–3 hour guided hike to see the sunrise over the crater and Lake Batur; most operators include transport, guide and breakfast; depart from Ubud around 2:00–3:00am.
Book a half-day local boat to snorkel reefs and hidden bays (many operators run trips mid-morning and early afternoon), suitable if conditions are calm.
Short drive from Amed to Tulamben for one of Bali's best snorkel/dives — shallow wreck and abundant reef life; best in calm morning conditions (dawn–midday).
If you want souvenirs or beachwear, a quick transfer to Seminyak (30–45 min) will get you to boutiques and markets; otherwise stay local and stroll the Uluwatu shops.
