Penida Island, a stunning destination near Bali, is primarily accessed via fast boat from Sanur or other ports. While adventurous travelers can explore solo by renting a scooter (beware of rough roads), guided tours are highly recommended for ease of transport, safety, and efficient sightseeing, often including transfers from Bali. The ideal time to visit is during the dry season (April-October) for optimal weather and sea conditions, as the wet season can bring challenging travel. A typical visit can range from a day trip covering major highlights to 2-3 days for deeper exploration and activities like snorkeling or diving. Costs vary; expect around $20-30 USD for a return boat ticket, $5-7/day for scooter rental, or $50-100+ for a guided tour from Bali. Other insights include its fame for iconic cliffs like Kelingking Beach, exceptional marine life for snorkeling/diving, and the necessity of carrying cash due to limited ATMs.
