Griff Rhys Jones is making it clear that his new Channel 4 series, "Griff Across the Alps," is not a leisurely holiday. The six-part program follows the 72-year-old comedian on a demanding journey spanning France, Switzerland, Italy, Austria, and Germany, concluding in Slovenia.

In the initial episode, Rhys Jones navigates the French Alps, beginning near Mont Blanc. Despite his insistence that the series avoids the typical celebrity-on-vacation trope, he is shown relaxing in a thermal spring bath, a stark contrast to the strenuous activities that follow. He describes the thermal waters as having flowed for 6,500 years, a thought that elicits a sigh of contentment.

Rhys Jones engages in physically demanding activities, including abseiling down a steep rock face, an experience he describes with a mix of trepidation and forced humor, hoping to capture some of the "sheer terror involved in mountain climbing." The logistics of his descent are questioned, with the presenter appearing mid-climb without a clear explanation of how he reached that point.

Upon reaching the base of the cliff, Rhys Jones connects with local chef Jean-Marie, with whom he learns to prepare a traditional dish. This culinary exploration comes after his adventurous descent, highlighting the varied experiences packed into the program.

The series also documents Rhys Jones's experiences with altitude. He visits the Refuge de Goudet, a climbers' dormitory situated at 12,500 feet, reaching it via a helicopter lift. The altitude affects him, leaving his knees shaky as he observes a cement mixer being lowered to a crew below, admitting, "I'm just holding on for dear life here." He reflects on the inherent risks, noting, "One slip and you go thousands of feet down."

Rhys Jones, who has been teetotal for over 40 years and has previously spoken about his struggles with an eating disorder, maintains a disciplined lifestyle. This background is contrasted with the hearty meal he helps prepare, suggesting a balance between his personal discipline and the experiences of the journey.

The program promises a blend of adventure, cultural immersion, and personal reflection as Rhys Jones traverses the diverse landscapes of the Alps.
