Discussion Exploring Halong Bay: Must-Do Activities

Hey everyone! I'm really excited about my upcoming trip to Halong Bay, just a couple of hours from Hanoi. I’ve heard so much about its stunning limestone karsts and emerald waters, but I want to make the most of my visit. What are the must-do activities or experiences in Halong Bay? Are there any cruises or hidden gems you’d recommend? Also, how do you feel about group tours vs. going solo? Looking forward to hearing your thoughts!
