My father-in-law picked this book up at Costco. We keep it in our glove box for spontaneous adventures with the kids (I have a 10 and 12 year old). We've hiked several trails using the book as our guide. There are some wonderful hikes we would have missed out on had we not had the book. The book lists the length and difficulty of the trail as well as the view and setting along the way (It's nice to know ahead of time if the hike is worth the effort). With a detailed description of hiking trails all over Oregon, this book would benefit even those without children; it's a great guide for young and old alike!
I only used this book to find one hike in Oregon so my comments may not apply to every trail. The hike we picked was reviewed as very easy. We drove 20 miles from our campground to get there and were immediately flabbergasted that anyone would recommend this trail for kids. From the book's description we expected an easy, spacious, safe trail near a river. Instead we found a difficult trail that would challenge some adults. From the parking lot, the trailhead started with a steep, off-camber climb with a precipitous drop off the side. The trail wasn't wide enough to walk side-by side with a child. In our two-family group, all 3 children were under 5, so we didn't even attempt any of this trail. Perhaps further along the trail widens and mellows, but the book never mentioned the difficult start. It would have been very helpful to have a better description of the trail along with an age recommendations for the difficulty level. What might be easy for 12 year olds, is not even approachable by younger kids.
I've been using this book for three years ever since my youngest daughter turned four. We have done 20 or so of the recommended hikes and my copy is now well worn. All I have to say is it's a great book. Each trail description has a map, driving directions to the trailhead, approximate length, and difficulty. I have personally found the difficulty ratings to be extremely accurate although of course it's dependent on the individual child. It's too bad the reviewer from San Fran had a bad experience but I don't think it's fair to criticize this book based on one hike. I have personally never gone wrong with this guide. Unfortunately, now that my youngest daughter has turned six, we are not using the book as much simply because she is now capable of tackling many adult level hikes!
