More than 50 bicyclists lined up outside the Honolulu Zoo Sunday morning to take advantage of the free admission on “Bike to the Zoo Day.”

This was the 8th annual event and its most successful, with more than 200 people cycling to the zoo.

There were prizes and free bicycle valet service, supported by the Hawaii Bicycling League, all to encourage people to ride bikes on shorter trips.

“People don’t realize how fun it is, but we had so many families come through here,” said coordinator Chris Sayers from the city’s Dept. of Transportation Services. “They had a good time, and sometimes it might be bike to the zoo day, or bike to the beach, or bike to the store, so there’s a lot of short trips that the bike is a good vehicle.”

And May is National Bike Month, so Sayers there are more events in store. This week is Bike to Work Week and Friday will be Bike to Work Day with a pau hana evening event in Kakaako.
