The City and County of Honolulu celebrates the 6th Annual Bike to the Zoo Day this weekend.
Anyone who rides a bicycle to Honolulu Zoo on Sunday, May 18, between 9 a.m.-2 p.m., will receive free admission.
Bicyclists must enter from the Monsarrat Avenue gate.
The city said the event is designed to encourage people to visit Honolulu Zoo and ride bicycles for short trips instead of driving their cars.
There will be free valet bicycle parking available and the first 200 bicyclists will receive a free bag with prizes.
