Vietnam Backpackers

South East Asia Backpacker has tried and tested adventures across the region and handpicked a selection of only the BEST companies to work with.

Why we chose Vietnam Backpackers Hostels?

Vietnam Backpacker Hostels are legendary on the Southeast Asian backpacker trail for one reason. They provide so much more than just a bed. The second a backpacker arrives at one of their hostels or signs up for a trip – they become part of a huge family that looks out for one another – meaning that it’s impossible to ever be lonely again!

Their value-for-money trips are designed for backpackers who are wanting to cram in as many activities and meet as many people as possible. Be prepared for non-stop fun when booking a trip with these guys!

We first met the Aussie owners of the hostel chain, Max and Mick, almost 10 years ago when they only had one hostel in Hanoi. They now have several all across the country and their success is a testament to the fact that they understand backpackers and know how to organise some of the best trips in the country! Having been backpackers themselves back in the day, they know what a backpacker wants and how to provide it to them.

With their awesome team, you’ll get to visit exclusive and off-the-beaten-track destinations, hang out with like-minded travellers, enjoy incredible activities and feel safe in the hands of a professional tour operator and Vietnam’s best guides!

  1. Kaberly

    Castaway Island is a vacation away from vacation. Yes, that is a real thing! Southeast Asia can be arduous, and the hostel made everything a breeze, and sent me home with the top memories of my trip. Having been to Halong Bay on three different accounts this was the most fun, and best bang for the buck. Every backpacker needs this on the books!

  2. John Reed

    Awesome 3 days, lots of partying and great fun! The hosts are cool as well, highly recommend

  3. Georgia Wilkinson

    ‘An amazing experience in one of the most beautiful places in Vietnam. Fun filled activities, energetic hosts and a great bunch of like minded people. A surreal 3 day adventure that you’ll never forget! ‘

  4. Jake

    Really great experience! Met lots of fun people. Partied all day and night, and experienced the bay with some great adventures (kayaking, tubing, etc.).

  5. Courtney

    Halong bay with HBH was literally the funniest weekend I’ve ever had. I don’t know if it was just our group or what but every single person on this trip (like 40) was awesome and so much fun. I only slept for 20 minutes because I didn’t want to miss anything.

  6. Chris Walker

    It was litty, my dude.
