When I went to mexico many years ago, they had dedicated teams of conservationists mark and monitor all nesting spots (they didnt collect the eggs), then when they start hatching they will rake the sand in a path to the ocean and inevitably a crowd of tourists will gather so the conservationists also end up having to hold the crowd back so that they dont get in the way, the crowd does however scare away any beach predators.

I got to see both egg laying, and eggs hatching it was very cool. The baby turtles are sooo tiny and adorable.
