The alarm was raised at 10.04am on Sunday about the casualty near Eilean Donan Castle in the Highlands.
He and his partner had pulled over to take photographs of the landmark when he fell off the rocks and landed in the loch below.
His partner then ran about a quarter of a mile to the tourist attraction to raise the alarm, according to the RNLI.
Kyle lifeboat The Spirit of Fred. Olsen was launched and arrived on scene at 10.22am.
The casualty had already scrambled out of the water and was stuck on the shoreline at the base of the rocks.
A Scottish Ambulance Service paramedic managed to get down to him and assess his condition.
Due to his injuries, the man could not climb further up so he was transferred by the vessel to an ambulance.
He was then taken to hospital for treatment.
A Kyle RNLI spokesman said: “Whilst visiting the area on holiday, the couple had stopped in a lay-by to take pictures of the castle when the casualty fell off the rocks and landed in the water below.
“His partner then ran about a quarter of a mile to the castle to raise the alarm.
“The currents are extremely strong in that area, however he managed to get to the shore and hold on until help could arrive.”
