Ciel, aged 11, held up a placard containing the message 鈥楴orth Yorks Council Stole My Bus Pass!鈥 in front of the crowd watching performances on the West Holts stage.
The youngster, from Bilbrough near York, is one of hundreds of children affected by the new rules, which mean free transport will only be offered to a child鈥檚 nearest school.
The previous policy was aligned with the admissions system with free transport available if you attended your catchment school.
Ciel attended the Somerset festival with her parents Kathy and Eric Walker.
Kathy got in touch with the School Transport Action Group (STAG) after finding out in May that her daughter would not be eligible for free transport to her catchment school, Tadcaster Grammar School.
Instead, she would need to attend a school in York to be eligible for a bus pass because this school is around 170 metres nearer.
Kathy said it came as a shock to be advised by the council that Ciel would not get free transport.
She added: 鈥淭his was the first we heard about it.
鈥淏ecause Ciel goes to a primary school in York we didn鈥檛 get told and Tadcaster Grammar has admitted they never passed it on.鈥
On the protest at Glastonbury, which took place during a set by Scottish multi-instrumentalist corto.alto, who is managed by her husband, Kathy said: 鈥淚t was a good opportunity to get a bit of exposure for our campaign.
鈥淚t was also a bit of fun because trying to fight this policy can be a real slog and you spend a lot of time sending emails etc.
鈥淚t got a lot of funny looks and laughs.鈥
The protest took place on the same stage as controversial performances by Kneecap and Bob Vylan, which are the subject of a police investigation following comments and chanting on the war in Gaza.
North Yorkshire Council has repeatedly defended the policy change.
It told parents at a recent council meeting that the home-to-school policy was aligned with statutory guidance issued by the Department for Education, which requires authorities to provide transport to a child鈥檚 nearest school.
The statement added that the policy could result in savings of up to 拢4.2m by the end of the implementation period at a time when school transport spending had increased to 拢50m a year.
Council leaders say they will review the policy next summer.
