You don't need a tank and dive gear to swim with humpback whales in Tonga! Many people think that you need to be a qualified diver to join our trips, but the great news is that all you need is a snorkel and mask! - which we'll provide if you don't have your own.
It's a good idea to have a bit of practise before you arrive so you can get used to wearing the mask and breathing through the snorkel. We'll be there to give guidance and tips if you need a bit more advise when you arrive, so don't worry!
I was lucky enough to take my mum on last years trip to Tonga. She had been very ill the previous year and her outlook on life had changed significantly. So much so that she decided swimming with whales was now on her bucket list! Now this isn't something that she would normally even think about doing so I was really surprised when she told me she'd be joining me! She's not the most confident of swimmers in open water and she only learnt to snorkel a couple of months before the trip but she did incredibly well and swam with more than a dozen different whales during the 5 days on the water.
So if you are worried about how competent you are at swimming or think age is an issue then stop worrying and just jump in :)
