When one of Washington’s most breathtaking state parks is part of your everyday life for 12 years, you tend to gain some unique insight.

That’s what Deception Pass State Park Manager Jack Hartt is hoping readers will take away from his new book, “Exploring Deception Pass,” which will be available later this month through Amazon.

Hartt has worked 38 years for the state park service, the past 12 at Deception Pass. He lives on Fidalgo Island within the state park.

“I always realized there’s a lot to this park that most people don’t know about but would love to find out about to expand their knowledge and ability to enjoy the park,” Hartt said. “I think when people understand a place, they appreciate it more and get to enjoy it more.”

Hartt said the book covers everything from the park’s plants, wildlife, geology, history and places to explore to a human spin on more personal stories from his time at the park, including “my embarrassingly bad sense of judgment.”

He said the book offers insider tips such as where to find a secluded swimming beach away from others, places where movies have been filmed and tips on how to beat the system and land a camping reservation.

“There are things that are uncommonly known such as the underpass under the highway and the waterfall in the park,” he said.

This is Hartt’s second book. He co-authored “Two Hands and a Shovel” with Sam Wotipka in 2013, a book about the Civilian Conservation Corps’ work at Deception Pass.
