Tour B was amazing. At first we were apprehensive because many travellers, hotel owners, and people we met said tour B was the worst one and not very good. But, this is the best thing about tour B. There are very few tourists, only five people on our boat, beautiful destinations, and a lovely day out. After doing all four tours, we found tour B was our favourite compared the the other very busy, overcrowded, and commercial other tours. The only thing to note is that I wouldn't recommend booking online for these tours. El Nido is full of tour shops who offer these tours for a cheaper price with things like wet shoes, kayaks, and snorkelling equipment all included in the price. Every tour we went on that we booked online we had to pay extra to hire these things.
