Memaloose State Park is much bigger than I anticipated. There are several loops and the incline makes it interesting for biking and walks around the park. I like that the park is along the Columbia River Gorge but, it is difficult to access the park if you are driving east and there isn't access to the river. 

The coolest part about the park is that there is a trail leading to an active railroad which is great for train spotting and photos. Not so great for noise.
