We woke up at 6:30am and it admittedly felt a little strange when we remembered that we were on a boat in Halong Bay. We sat with the Australian family again whilst eating breakfast and we were then piled onto the small wooden boat. We sailed through Halong Bay to 'Hang Sung Sot Cave' which involved a tiring climb up a set of steep steps to the entrance. Our guide explained the history of the cave which was prettily lit up. It was discovered by the French, in 1901, at 25m above sea level with a roof height of approximately 30m and the passage inside being about 500m in length. The cave consisted of three chambers, the last one being huge, connected by small passageways. It was full of stalagmites and stalactites and although our guide pointed out a dragon and rock formation the most obvious formation was the one that was lit up by a red spotlight and looked like a huge phallus! It was somehow so hot inside the cave and although it wasn't a strenuous walk we were sweating so much when we made it out of the other end. We returned to the junk boat and chilled out in a big comfy seat whilst cruising through the bay. We anchored fairly close to shore for lunch and then made our final journey in the small wooden boat. We were told our bus would arrive in about ten minutes but we were stood waiting for over an hour! We had become quite accustomed to the waiting game in Asia and knew to add on at least another fifteen minutes when we were told something would take only five minutes or so. We were glad when it finally pulled up as it had started to rain, so we got on board ready for the four journey back to Hanoi. However, we only managed to travel a couple of km down the road before we turned around as our tour guide had left someone! We had a break around half-way before reaching Hanoi at around 5:30pm where we had to get dropped off at the 'Travel Agent' as this was where we had been picked up. This was convenient somewhat as we needed to pick up a receipt for a free taxi journey to the airport for the following day. The owner insisted on giving us another free bottle of water before telling us where to head to reach 'Hanoi Hostel'. However, the map we were given didn't quite match up with the actual street layout so we ended up walking around for quite some time. In the end I demanded to sit on a kerb whilst Andrew went to search for the hostel because even though we were on the right street the numbers were in no order whatsoever! He soon came back to tell me it was just a short walk away, which it was, so we eventually checked-in after a long day. It was a pretty nice, old building but we had difficulty as the key we had been given wouldn't open our room door. The member of staff also had the same trouble so we were shown to a different room. It had a double bed as well as a single bed and mother-of-pearl inlay furniture along with a mini-bar. We literally collapsed on the bed and didn't even bother to go out to eat even though we were hungry. We set our alarm for 3:30am and went off to sleep.
