turtle hatchlings

We are going to Tambor beach end of March and are really hoping to see some baby sea turtles hatch. or perhaps help them get safely to the ocean if that is done. Does anyone have any info on this? What beach might we find some at? We are avid turtle "guardians" and have rescued many from hazardous roadsides - some injured some still safe - and have been involved with the Turtle Rescue Centre in Central Ontario. Experiencing this in Costa Rica would be fabulous.
