Meet Our Outdoor Nursery Team
Katriona Arnold - Nursery Director
Kat brings over 15 years of experience in drama and musical theatre, having taught children of all ages in both educational and recreational settings. Her background in performance means she has a natural gift for capturing children's attention and bringing learning to life through storytelling, role play, and imaginative play.
With a strong track record of working in outdoor settings, Kat blends creativity with nature-based learning in a way that sparks curiosity and wonder. She has a unique ability to connect with children on their level, building trust and confidence through joyful, engaging sessions.
Whether she’s leading a woodland drama game or guiding a quiet moment of reflection under the trees, Kat brings energy, empathy, and enthusiasm to everything she does. She is passionate about emotional well-being, creativity, and helping every child feel seen, valued, and inspired.
Matthew Arnold - Nursery Director
Matt Arnold is the co-founder and Nursery Director of Hidden Valley, the thriving outdoor nursery he runs alongside his wife, Kat. What began as a patch of bare woodland has blossomed, inspired by their baby son Freddie, who is a daily reminder of the preciousness of the early years and the magic of childhood adventure.
Matt's approach to leading Hidden Valley is rooted in a unique and demanding professional background. For a decade, he sailed the world in the yachting industry, a career that forged invaluable expertise in leadership, disciplined teamwork, and high-pressure risk management. These skills are now the bedrock of the nursery's ethos, ensuring children enjoy the freedom of the outdoors within a safe, structured, and profoundly nurturing framework.
When he's not guiding young explorers through the woods, Matt is pursuing his own deep passion for the wild. He is a dedicated outdoorsman, happiest when backcountry ski touring, climbing mountains, or wild camping beneath the stars. His commitment to adventure was recently tested on a five-day, self-supported trek across Iceland, an experience that further cemented his belief in the transformative power of nature.
Matt channels this same adventurous spirit into helping children take their very first intrepid steps.
Beyond his work at the nursery, he serves the local community as an on-call firefighter in Grayshott, demonstrating his profound commitment to teamwork, resilience, and service, values he brings to the heart of the Hidden Valley community every day.
Kaila Hamilton - Nursery Manager
Kaila has ten years of experience working with children across a variety of settings, as a nanny and at children’s parties. She is passionate about supporting children as they grow, helping them to believe in themselves and to reach their full potential. It brings her joy to empower them to ask questions, make decisions and to take on a leading role in their learning journey.
One of the things she loves most about working in a forest school is seeing how the natural World sparks children’s curiosity, imagination and resilience. Whether it’s making mud pies, building dens, or spotting bugs, the outdoors offers endless opportunities for play, learning and adventure. She feels incredibly lucky to be able to share her love for nature with the children and help them build a strong connection to the World around them
Kaila feels she has truly found her dream role – one where she can inspire children while also experiencing the calm, tranquility and sense of safety that the forest brings. It’s a place where everyone can slow down and savour each magical moment. In the forest, there’s no rush; each day unfolds at its own pace, offering something new and exciting. This environment allows Kaila to shine, planning in the moment and making the most of every opportunity that arises from the discoveries and curiosity of her little explorers.

Alice St Aubyn - Nursery Advisor & Forest School Leader
With over 15 years of experience working in primary schools, I have always been passionate about outdoor learning and used it as a powerful tool to engage pupils. During this time, I held roles such as PSHE Coordinator and Wellbeing Coordinator, where I focused on supporting children’s holistic development, meeting them where they are, and finding creative ways to inspire a love of learning.
For the past 5 years, I have worked in nurseries as both a Manager and Deputy Manager, taking on the role of SENCO in my last two settings. Inclusive education is something I feel deeply committed to, and I strive to ensure every child is supported to reach their full potential.
Two years ago, I qualified as a Level 3 Forest School Leader, which has allowed me to combine my love of nature with my teaching practice. I particularly enjoy encouraging children to take safe risks, explore their imaginations through the natural world, and develop confidence through hands-on experiences.
Alongside my love of the outdoors, I bring music and creativity into my practice—I sing, play the ukulele, and make up silly songs to engage children in learning and help them remember routines in a fun, memorable way.
Outside of work, I enjoy hiking and mountain biking with my husband and our 6-year-old, and I look forward to sharing those adventures with our newest addition to the family too.
