Tom Travels evaluates five top day trips from Da Nang for 2025. The Cham Islands offer snorkeling, diving, and overnight homestays for $10, with return ferry and environmental fees totaling about $15–18. Ba Na Hills costs $38 including cable car but can be disappointing in bad weather. My Son Sanctuary, a UNESCO temple complex, costs $6 and is best visited at sunrise. The Son Tra Peninsula features the 67-meter Lady Buddha statue for free, with scenic driving routes requiring a proper motorbike. Marble Mountains, five limestone hills with caves and pagodas, cost $1.60 entry. A common scam of fake paid parking is highlighted. The guide notes seasonality: avoid Cham Islands from October to January due to rough seas. For time-pressed visitors, Marble Mountains and Son Tra can be combined in one day. Each trip includes practical advice on transport, costs, and avoiding tourist traps.
