We spent the day going from Da Nang to monkey mountain, Hai Van Pass, Elephant spring, finishing at Hoi An. It was a day my boyfriend and I will never forget. A long day but its worth it for all you get to see (pick up at 8am and finished at 4.30pm). Trong is more than happy to snap away as you see the sights so you capture as much as you can to look back on. If you're considering it, just do it. You wont regret it.
