It's possible to hike the trek alone without a guide to Viet Hai Village, but the path is challenging, good shoes, fitness and hiking experience would be good, some bits need to be climbed and throughout thick jungle, watch daylight hours! Takes about 2-3 hours. Ask the woman by the first restaurant after the path ends for a boat taxi back to cat ba, her sister will come pick you up in a small old fisher boat at the harbour 4km away from the village (1 hour walk), best experience to see the iconic islands and floating fisher village without some overcrowded tourist boat tour.
