The Sugar City Trail features some small, jumpable bumps, table tops, and curvy banked turns. This attracts both intermediate riders and those seeking more excitement. While some sections are exposed, the bumps can be safely rolled over or taken with more speed to get some air. However, cows can damage the trail during wet weather, so be cautious. The trail ends on a flat section at the bottom of Big Valley Trail, allowing riders to climb back up and take multiple runs.

The Tree Frog Trail is an exhilarating flow trail designed by the same team that created the Tamarancho Flow Trail. It has quite a few turns and bumps that make for a rollercoaster ride. While it can be ridden in either direction, it's more enjoyable and safer when ridden downhill. The trail then descends through rolling hills and forest, offering shade as well.

Carquinez Scenic Drive, a once popular roadway for cars, has been closed since the 1980s due to landslides that caused damages. However, the former road has now been transformed into a beautiful paved park trail in the Carquinez Regional Shoreline Reserve on the east, and a well-rebuilt paved bike path on the west of the oil dock. The trail is a great spot for biking and offers a shaded area with several scenic viewpoints that overlook the stunning bay.
