Michelle is in Mallorca to visit American diplomat James Costos and his partner, Michael Smith.
Her husband, former President Barack Obama, does not appear to have accompanied her on the international trip.
The day after her hike, Michelle boarded a yacht, wearing a white crop top and a stylish wrap skirt with a bird pattern, letting the fabric flow to show her toned legs.
The former First Lady, 53, shielded herself from the sun with shades and a black hood to enjoy a hike around the island on Thursday.
She was surrounded by members of her staff tagging along for the sweat session, with members of her security team flanking her.
She accessorized her outfit with a straw bag from Madewell, giving the outfit a chic beachy wibe.
Michelle was seen aboard the yacht later in the evening on Friday, enjoying time with a group of friends.
At one point on Friday, she changed into different clothes, and was spotted wearing a black outfit and a hat while leaving a restaurant.
Both she and her husband will have a Secret Service detail for the rest of their lives, Barack having restored lifetime protection for former presidents in 2013.
They will also be trailed by paparazzo’s everywhere they go. here are some photos taken of Michelle Obama on holiday.
