On a recent road trip, I was hell-bent on finally seeing the petrified forest state park, and I got my wish! I'd heard mixed reviews about whether it was worth the visit, but overall I think it is if you like geology, mineralogy, petroglyphs, or scenic views of the Gorge. Unless you're a die-hard rockhound, you won't need more than 30-60 minutes to see all there is to see.
You pay a $10 day pass fee for state park access (which you can then use for the rest of the day at other state parks), and museum admission is by donation, but they won't give you stinkeye or anything.
Inside, there's a smallish museum and gift shop that's mostly dedicated to petrified wood. You'll see fossil maps of Washington, many samples of different types of wood found in different locations, and some locally found minerals such as Ellensburg blue agate.
The exhibits are kind of old-fashioned, with some typed labels and dated-looking displays, but that adds to the charm. Kids will enjoy the picture jasper slices that look like animals, faces, and other objects (like the "Fish Face" one), and there's a short movie about the geologic history of the area, but otherwise I'm not sure this is especially kid-friendly.
Outside and behind the museum, you'll see a display of larger logs of petrified wood, which may not look like much when you're driving up but are very colorful and textured up close, so don't miss those. There's a back patio with a scenic view of the Gorge and the river, but no shade and minimal seating, so it's not very tempting to stay out there long in summer. There's also a display of petroglyphs down a short ramp around the side of the building, which is very cool and definitely worth seeing.
The posted hours on their website are as follows: Summer hours are 6:30 a.m. to dusk, and Winter hours (November 1 - March 1) are 8 a.m. to dusk. However, we tried to go on a Sunday afternoon on a previous summer trip and the museum was already locked up -- I think the fence was shut, so you couldn't even go up and see the outdoor stuff -- so take it with a grain of salt. Honestly, the Gingko Gem Shop located outside the park entrance is almost as good if you're only mildly interested in petrified wood and minerals. ;)
