One of Florida's more surreal wildlife encounters is spotting manatees in the warm-water discharge canals of coal-fired power plants. Yet these placid mammals show up here so reliably from November through April that this is now a protected sanctuary. Look for tarpon, rays and sharks, too. A snack bar, small exhibit, bathrooms and picnic tables round out the sight.
It's half an hour from downtown Tampa; take I-75 south to exit 246 and follow signs.
