Girl Scouts are invited to join the park’s naturalists for a fun-filled learning adventure on Grandfather Mountain. Plus, all Girl Scouts and troop leaders are admitted free with proof of membership (all or part of a uniform or a troop roster with the leader’s name on it), and family members will receive discounted admission ($1 off child admission and $2 off adult admission). Advance reservations for park admission are not required, meaning scouts, troop leaders and family members are welcome to arrive the day of the event without admission tickets already in hand.
