Madonna's daughter Lourdes Leon makes the most of her summer break with zip-lining tour of the French Riviera

They've been partying up a storm since arriving in the French Riviera last week.
And Madonna's children Lourdes Leon and Rocco Richie enjoyed another fun-packed day as they ditched their family for a leisurely bike ride and some ziplining in Villefrance-sur-Mer, France on Tuesday.

Learning the ropes: Lourdes Leon and her brother Rocco Ritchie enjoy an adventurous day of bike riding and ziplining while vacationing in Villefranche-sur-Mer, France on Tuesday

The 16-year-old was spotted with her 13-year-old brother and their friends as they rode their bikes from their villa to a remote part of town.
Lourdes -- whose father is actor and personal trainer Carlos Leon -- beat the summer heat in a bright orange vest top and black yoga trousers.
The teen wrapped up her long black hair in a pony tail and kept her accessories to a minimum, just wearing her favourite pair of necklaces and a few rings.

All ready to go: The 16-year-old geared up in an orange safety helmet and gloves

Adventurous: The teen showed not an ounce of fear as she pushed off

And hopefully she wasn't riding her vintage yellow bicycle too fast as she left her sturdy black trainers untied.
After the ride the brother-sister duo took in one of the best views of the city by jumping on a zip-line.
Adventurous Lourdes was eager to get aboard, strapping herself in and donning an orange helmet and leather gloves for her safety. 

Away we go: After the ziplining session, Lourdes and her friends hopped on bicycles

The day before Lourdes enjoyed a sunny dip in the Mediterranean Ocean with two of her male friends.
The trio were spotted walking along an oceanside promenade in their swim gear before heading off to lunch at a nearby cafe. 

Fashionable: The teen donned a bright orange vest and yoga trousers

Welcome break: Lourdes is enjoying her summer break before school starts up in September

Lourdes, who returns to school on September 9 at the LaGuardia High School of Music & Art and Performing Arts in New York City, is in Cote de Azur in the French Riviera with her mother Madonna and siblings Rocco, Mercy and David.
Also on tour with the family is Madonna's 25-year-old boyfriend Brahim Zaibat.
The family is marking two birthdays on their trip, starting with a paintball fest for Rocco's 13th birthday on Sunday.  

Just her and her boys: Lourdes Leon and a pair of friends headed off to the beach in Villefranche-sur-Mer, France on Monday

Teenage wasteland: The kids are all on holiday before returning to school at the end of the month

The group surely have made plans already for mother Madonna's special day -- marking the big 55 -- on August 16.

The Material Girl has already started the celebrations as she and her Brazilian toyboy paid a visit to Menton, a picturesque coastal town close to the French-Italian border last week.

Madonna took the opportunity to visit the annual Festival de Musique Menton – a classical music concert where she watched pianist sisters Katia and Marielle Labèque and Basque band Kalakan, with whom the singer is close friends.
