Set your alarm to depart before dawn for Cape Romain National Wildlife Refuge for this firsthand look at how turtle teams help protect loggerheads during nesting season. When participants reach Boneyard Beach on Bulls Island, they’ll join naturalists to search for crawl marks and signs of turtles building their nests before the incoming tide washes the evidence away. Proceeds support the Sea Turtle Program through the Coastal Expeditions Foundation. Garris Landing, 498 Bulls Island Road. Sunday, 5 a.m. $125. (843) 884-7684, www.coastalexpeditions.com
