I did a 2 day 1 night Hang En tour on August 23rd with guides Hung and Huy. I had an amazing experience on the tour. The operation is organised profesionally, there are actually more porters and guides than the tour participants and the team makes every effort to make you safe and comfortable. The cave was amazing and swimming in the cave lake was an unforgettable experience. As for the trip itself it was not hard at all, just very hot and sweaty in August. The only hard bit came at the end, when we had to climb a high hill for an hour and a half, but at the end there are cold drinks waiting for you to make it worth. I.would like to thank the team and Hung and Huy for unforgettable experience, one of the best I had in Vietnam. Not to be missed.
