Heading south on Goldmine Trail out of the parking lot, Dynamite Trail breaks off to the right after less than a quarter mile. Dynamite is a sustained, steady 400-foot climb over the next mile-and-a-half. The trail is wide and mostly smooth, hardpacked dirt with embedded rocks, and most intermediate riders can probably make the whole climb on the middle chain ring. Although the brittle-bush covered hillside in this area of the park is not particularly scenic when not in bloom, as you gain altitude you get a more expansive view back over the east valley.
A little over half-way up you'll be able to see across the valley to the west to San Tan Mountain, which is actually not part of the park. After cresting the summit, you descend past a set of signed switchbacks. There are some fun twists and turns as you pedal along in and out of some washes and eventually connect with San Tan Trail
