Whether you are staying in Hanoi prior to your trip or arriving on Day 1, you will need to make your way to the front entrance of the Hanoi Opera House at 10:30 to meet the rest of your group. We then transfer you over land and sea to our hotel on Cat Ba Island, which takes approximately five hours.

Once we arrive and have had a chance to settle in, we’ll take a short ride to the local beach for our acclimatisation swim. This is an excellent chance to get familiar with the local conditions before we head back to the hotel for our welcome meeting and then first dinner of the trip in Cat Ba town.

This morning, we head straight out into Lan Ha Bay for our first swim among the limestone islets. Leaving Ben Beo port, we travel past traditional floating fishing villages, where many families still live and work today. We arrive at the Nam Cat islands where we carry out our first swim. On the way, we pass Castaway Island and Moody Beach, finishing at Turtle Island (Hòn Rùa). It is a magical place to finish our first full swim of the trip.

After taking lunch on-board the vessel (prepared by our boat crew), we’ll head over to Viet Hai Port, where we will take a scenic walk through the forest to a small village. After a quick break we take an electric car back to our boat and then continue on to our afternoon swim. We move further into Lan Ha Bay, cutting into a series of small bays, before finishing our swim at Temple Beach.

We set out in the morning to continue island-hopping in the bay, dropping into some of Lan Ha Bay’s deserted beaches as we go. In the morning, we swim across six yellow sand beaches, before completing a crossing over to Ba Trai Dao – or Three Peaches Island – where we explore some of Lan Ha bay’s stunning arch formations.

After lunch on the boat, we head off from Ba Trai Dao, exploring some of the bay’s hidden caves and lakes! We finish the swim off on one of Ba Trai Dao’s many sandy beaches.

This morning we head out to Cat Dua Island (also known as Monkey Island), where we will undertake a circumnavigation of the island. We’ll then relax and have lunch on the boat after our morning swim is complete.

After getting back on board we return back to our hotel, where the afternoon is yours to do what you wish. You may wish to explore Cat Ba Town, visit the national park, undertake the spectacular cliff-side walkway, or just relax at the rooftop pool at our accommodation.

Today we start travelling further afield and make our way out to the bay’s eastern flank and Dau Be Island – the most remote part of Lan Ha Bay. There are some wonderful swim throughs along these coastlines, as well as sea stacks and high cliff walls. There are hundreds of swimming options and we will pick the best one based on local conditions.

After lunch on our boat, we will head off to complete a swim along the cliffs of Hang Trai. These dramatic cliff walls are home to caves, hidden inland lakes, beaches and limestone outcrops.

On our last full swimming day, we head off towards Hang Sang, the most Northerly part of Lan Ha Bay. From here, we will work our way down the coastline, exploring bays as well as entering an inland lake. Keep your eyes peeled for monkeys! We finish the swim at Hòn Bút (otherwise known as Candle Island), one of the thinnest limestone stacks in the whole bay.

After lunch, we head back closer to home, to Bai Lut (flooded beach). This tiny beach joins together two limestone islands and completely disappears at high tide. After stopping on the beach to enjoy the stunning views out over the bay, we swim along a series of bays to finish at an abandoned beach resort.

On our final morning, there is a chance for a pre-breakfast swim before we take a walk up to Hospital Cave, located in the National Park, which was built as a bomb-proof hideout as well as a hospital for Vietnam soldiers.

This is a fantastic final activity on an amazing SwimTrek adventure before we transfer everybody back to Hanoi Opera House in central Hanoi. You can then extend your Vietnamese experience on the mainland, or make your own way to the airport for onward travel.

We have given this trip a ‘Moderate’ grading. Most swimmers comfortable in the open water will be able to take part and enjoy one of these trips.

Swimming Distances

*Please note that these swims are an example of what may take place during your trip and should be used as a guide only. Actual swim locations and distances will vary according to local weather and swim conditions.

Swimming Conditions

Swimming in the open water is a fantastic experience, however you should be aware that certain marine life such as jellyfish, plankton, sea lice, sea urchins and coral could be present during the swims and may cause some discomfort. In all cases we will work on reducing your contact with these creatures and that any interactions are managed safely. If you suffer from anaphylaxis, please consult the office prior to booking.

Due to the runoff from the lush, green islands, which make up this beautiful corner of the world, water clarity is lower than in other open ocean locations. However, it is still suitable for swimming.

Like many locations across the world, certain areas may contain litter, and if necessary, our guides will adjust swim routes to ensure we are in the best quality water.

Temperatures

*Please note that these temperatures are indicative and should be used as a guide only.

Weather Caveat

For safety reasons, we rely on decent weather conditions when carrying out our swims. As a consequence, open water swimming holidays require a certain degree of on-trip flexibility which can result in changes to the planned itinerary. These changes often add a touch of uniqueness to your trip and will be communicated to you by your SwimTrek guides as quickly as possible.

Group Size

This trip has a maximum group size of 16. The group will be split into a maximum of three groups, based on speed, with each group being accompanied by their own safety vessel/escort. 

Boat Support

Boat support on this trip includes a main boat, three support watercrafts and three kayaks crewed by local pilots and your SwimTrek guides. Please note that this boat support is subject to change without notice and cannot be guaranteed.

Extra Activities

This trip starts and finishes in Hanoi, where there is the option to extend your Vietnamese adventure with a tour or extension, through our partners Vietnam Insider Travel. This could include a walking tour through Hanoi’s Old Quarter to witness the city’s French architecture, soaking up the city’s rich history with a visit to Huu Tiep Lake (‘B-52 lake’) where US B-5 bomber wreckage can be seen, discovering temples including Hanoi’s Temple of Literature or even sampling the local Vietnamese cuisine.

Equipment Checklist

For your basic, essential packing list, please visit our Packing List page on the website. For additional, location specific items, please see the information below.

SwimTrek will provide water and electrolytes at every location and refill your bottles.

Vietnam has two main international airports, Tan Son Nhat Airport (SGN) in Ho Chi Minh City and Noi Bai Airport (HAN) in Hanoi, which are both serviced by a large selection of domestic and international flights.

The easiest way to get to the start of your trip is to fly into Hanoi and then catch a taxi or public transport to the city centre to meet your group at the Hanoi Opera House on Day 1.

As SwimTrekkers come from all over the world, and join our swimming holidays in numerous destinations, we don't currently offer flights as part of our SwimTrek packages. We do however want to do as much as we can to ensure that our guests get the best deals when travelling to one of our trips so check out SwimTrek's tips to help you get the best deals for your flights page on the website.

Transport from Noi Bai Airport to Hanoi Opera House

The easiest option is a journey from Noi Bar Airport to Hanoi Opera House in the city centre by taxi, which will take approximately 30 minutes and will cost approximately 400,000 VND. Make sure you go to the official taxi rank located outside and take a metered taxi. An additional 10,000-15,000 VND will be added to your fare, but that is normal and the best way to travel is by taxi. Do not accept an offer of a taxi or car from elsewhere. Alternatively, airport minibus shuttles operate from the airport bus ranks into the city centre, as well as public buses.

Money, Extra Expenses & Tipping

The local currency in Vietnam is Vietnam Dong (VND). While USD is widely accepted, the conversion rate that is offered is usually poor, which makes it cheaper to pay in VND in most locations. While there is one ATM in Cat Ba town, please note that debit and credit cards are not widely accepted in Vietnam and it is suggested that carry enough cash with you for your daily expenses.

You should bring extra money with you to cover items such as meals not already included in your package, drinks, entertainment, souvenirs, etc.

In some countries, tipping (gratuities) is not part of the culture - in others it has become an expected norm. We believe that tipping is done entirely at your own discretion. If you have been provided with excellent service it may be something you wish to do. Your SwimTrek Guides can advise on local norms for service providers like boat crew, waiters or taxis. Nothing is expected for your SwimTrek Guides but many groups like to present something to the Guides at the end of the trip.

Responsible Travel

SwimTrek is conscious of the importance of protecting the world’s natural wonders. We are acutely aware of our responsibility to not only take care of the natural environments which we are lucky enough to explore, but also to educate our guests about the importance of conservation efforts and responsible tourism. It’s for this reason that we have worked so closely with our partners to ensure that our trips are conducted in the most responsible and sustainable way possible, working tirelessly to minimise the impact of our presence on local marine life and the natural habitat.

For more information, please visit our Responsible Travel page on the website.
