From fewer than 10,000 visitors a year, the zoo - one of 218 facilities nationwide accredited by the Association of Zoos and Aquariums - is now visited by more than 500,000 people annually, say county officials.
"Our parking lots are full even on nice, sunny days. We're very proud of that," said zoo director and veterinarian Dr. Hubert "Doc" Paluch, whose staff is hosting a variety of events to celebrate the zoo's 30th birthday, including evening tours, concerts and new educational programs.
Paluch cites the economy and a trend toward "green" pursuits among the reasons why the Cape May Zoo is packing them in.
"This park and zoo not only does its part in preserving open space and wetlands in an area where that is shrinking, it's also always been a place where families can come and enjoy an entire day together without spending very much," he said.
The facility, which relies heavily on funding from the county government, doesn't charge admission. As he directs drivers to the parking area, a volunteer collects dollars and coins in a plastic bucket bearing the word "Donations" in black marker.
Of the facility's $1.1 million operating budget last year, about $620,000 came from donations, which helped pay the salaries of 10 employees.
So popular has the zoo become that the county is expanding its parking, says Lenora Boninfante, a spokeswoman for Cape May County.
Brenda Douglas, of St. Davids, Pa., dropped a $20 bill into the pail on a recent morning before easing her family's SUV into the lot.
"I don't think that even covers the enjoyment we get out of coming here," said Douglas, who summers in Stone Harbor and often brings her three children to the zoo.
They enjoy the picnic area in the adjoining park and the miniature electric train that carries kids around the perimeter of the zoo.
