Search "whale shark tour La Paz" and every operator's page says roughly the same thing: small groups, certified guides, unforgettable experience. That sameness isn't an accident — it's also not very useful when you're actually trying to pick one. Here's what to ask instead.
"Small Group" Means Different Things
Some La Paz boats carry up to 24 passengers for a whale shark tour. Others cap at 10 or fewer. But here's what most marketing doesn't mention: CONANP regulations limit every operator, regardless of boat size, to a maximum of 5 snorkelers plus one guide in the water at any given time.
That means a bigger boat doesn't get you more time with the whale sharks — it gets you more people waiting on deck for their turn. The number that actually matters isn't the boat's capacity, it's the total number of guests split across those 5-person water rotations. Ask directly: "What's your total guest count, and how many rotations will there be?"
"A bigger boat doesn't mean more time in the water. It means more people waiting for theirs."
"Certified Guide" vs. Marine Biologist
Every legally operating tour needs a certified captain and a guide qualified to be in the water with guests — that's table stakes, not a differentiator. What varies is whether that guide is trained specifically in marine biology: able to identify individual whale sharks, explain behavior in real time, and position your group for a respectful, close encounter rather than a rushed one.
This is worth asking about directly rather than assuming from the word "certified" alone, since certification requirements and marine biology training are two different things.

A Note on Reviews
Review count and rating both matter, but for different reasons. Rating tells you about quality; review count tells you about sample size — a 5.0 rating from a dozen reviews is a smaller signal than a 4.6 from over a hundred. Read a handful of the actual reviews, not just the star average, before deciding.
