Hillary learned at Tuakau Primary School and then Auckland Grammar School. He finished primary school two years early, but he did not do very well at high school. At first, he was smaller than other students there and very shy so he felt safe with his books and often thought of a life filled with adventure. Every day, he rode a train to and from high school, and he often used this time to read. Learning how to box helped him become more confident. At age 16 his interest in climbing started during a school trip to Mount Ruapehu. Although very tall at 6 ft 5 in (195 cm), he was stronger than many of his fellow hikers.
