They are on the beach before sunrise. We walk the beach every morning to see the sunrise (so we get there about 15 mins before the sun cracks the horizon) and the Disney Conservation folks are already there doing their thing with ATVs up and down the beach. The groups tend to form a little after sunrise in our experience.Thanks everyone! Really wasn’t sure what we were exactly looking for, just curious to see what’s available. We will ask about it when we check in to see if tours are available, or what time to go to the beach in the morning. Thanks again!
