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.

This trail is a nice loop that is smooth and shaded for the bottom half, but it does get a bit steeper, rougher, and more exposed as you climb to the top. Alternatively, you can continue on the Contra Costa Feeder Trail and take the loop in the opposite direction for a less strenuous ride.

Pleasant, mostly shaded road with little midday traffic, though eastbound picking up around afternoon rush hour. Almost unbelievably rural feeling so close to the Bay. Unfortunately, long parts without shoulder.

The path is scenic, with fantastic views that take you across the hills of Almond Ranch and into the adjacent Sky Ranch territory. The trail has a few brief, steep areas that provide an exciting challenge as you climb. Taking this route in reverse is also an exhilarating experience as you navigate through a series of grade reversals put in place to drain water during heavy rains.

This overlook is just one of many along the car-free road that boasts breathtaking views of the bay. The wide shoulder provides ample space to pause, take a deep breath, and marvel at the natural beauty that surrounds you.
