When you go through the gate check on the island (you'll probably be given a temporary pass for your vehicle), continue on the main road to the Sanctuary right turn off - then almost immediately there is a left turn to the 'Tennis Center' - take the left and then an almost immediate left again - you should see a sign for the 'Tennis Villas' - we stayed there; this time in condo 4757 - just continue down to the end of the street; you'll see a wooden bridge which crosses the lagoon - look up to your right the osprey nest is there up high - I saw an adult bird on two different occasions (could have been the same one or the mates?). The nest is quite high so if chicks are present, doubt that you would see then? Hope this helps - I'm sure there are other osprey nests on the island. Dave
