They were guided through the process by the Central Beacons Mountain Rescue Team.
The Prince and Princess of Wales have abseiled together off a cliff in the Brecon Beacons, while meeting mountain rescuers.
William and Kate arrived at a wet and windy area of the Bannau Brycheiniog near Merthyr Tydfil in the South Wales Valleys on Thursday wearing hiking gear, and put on safety equipment ready for the descent.
They were guided through the process by the Central Beacons Mountain Rescue Team, a volunteer-run organisation which responds to calls 24 hours a day, all year round.
The group covers the central area of the Bannau Brycheiniog National Park which includes Pen y Fan, the highest point in southern Britain, and the Ystradfellte waterfalls, and has been keeping the surrounding communities safe for 60 years since 1963.
When asked by instructors if he had abseiled before, William said: “It’s been a while.”
Before heading over the edge Kate, who was wearing a red mountain rescue coat like her husband with her hair tied in a ponytail, was heard telling William: “We’re not racing.”
They are also set to take part in other training activities such as medical support exercises, watch a search dog rescue demonstration, and meet current and former team members to hear about their experiences spanning the organisation’s six-decade history.
The Prince is patron of Mountain Rescue England and Wales, and worked closely with such teams during his time as an air ambulance pilot.
William and Kate will later dry off and socialise with the climbers at the nearby Dowlais Rugby Club.
The club, which is a feeder club to Cardiff Blues, is a popular spot where the climbers socialise and relax when they are off duty.
They will also meet the owners of the Little Dragon Pizza Van, which draws people from across the country to try its food.
At the club they will get a chance to speak to individual volunteers, the organisation’s supporters and members of the local community.
After spending some time there they will meet more members of the public outside.
The royal couple will be staying in a local bed and breakfast this evening.
