"The team went down to a depth of 5 metres (16 feet) and found a large chamber ... but we've found no trace of the children," the navy unit said on its Facebook page.
A navy commander overseeing the search said he was hopeful the 12 twelve boys and their 20-year-old coach would be rescued.
"I believe they're all still alive but they might be exhausted ... we should get good news today," Rear Admiral Arparkorn Yookongkaew told Reuters.
People wanting to explore the cave are meant to get permission. Thailand is in the middle of its rainy season when caves can flood.
