Organised by the Pembrokeshire Outdoor Schools partnership, the event sought to highlight the importance of outdoor learning for children of all ages.
Graham Peake, Pembrokeshire Coast National Park Authority's Discovery Team Leader and Chair of the Outdoor Schools partnership said: "The day was a great success and has helped us to highlight the importance of outdoor activity for all children.
"Pembrokeshire has so many amazing outdoor experiences to offer, we hope that additional schools will take up opportunities to spend more time outside with their pupils."
More than 130 children took part from Stepaside CP School, The Meads Infant and Nursery School, Lamphey Primary School, Ysgol Clydau, Ysgol Bro Dewi VA, St Dogmaels CP School and Tavernspite CP School.
Each of the schools was invited to attend because of their great work in the outdoors over the past year.
Pembrokeshire-born Tori James, who became the first Welsh woman to climb Mount Everest at the age of 25, was on hand to present certificates to the schools. She also gave an inspirational talk to the children on the value of outdoor adventure for young people.
Following presentations by a number of the children, pupils participated in a programme of inspiring activities provided by Darwin Science, the Field Studies Council, Pembrokeshire Coast National Park Authority, Sport Pembrokeshire and Sustainable Schools Pembrokeshire.
Additional support on the day was provided by other Outdoor Schools partners including Pembrokeshire County Council, Healthy Schools Pembrokeshire, and the National Trust.
