The spot is chosen that morning
Which reef you get depends on the swell, the tide and the visibility, because a
spot that is clear on a calm day is unusable when there is water moving through
it. The boat works the whole stretch of coast and the captain calls it on the
water.
What is down there
Pufferfish, moray eels, rays, parrotfish and schooling jack around the
structure. Turtles on the surface between spots. This is Pacific reef, so it is
rock and boulder rather than the coral gardens of the Caribbean side, and the
life is concentrated where the structure is.
If you are not a strong swimmer
Say so when you book. There are flotation aids on board, the crew stays in the
water with the group, and nobody is asked to swim further than they want to.
Children do this trip regularly with a parent in the water beside them.
