The Grace Coolidge Trail is generally considered easy to intermediate for mountain biking. While much of it is flat, expect some uneven terrain with small rocks and roots. There's a manageable climb leading to Center Lake, followed by a fun descent. A specific segment, the Creekside Trail, is hard-surfaced and mostly level, making it very beginner-friendly.
You'll mostly ride on doubletrack or unpaved natural surfaces. A distinctive feature is the presence of many creek crossings. Some have narrow footbridges, but others may require you to pedal directly through the water, which can be deep enough to reach above bottom brackets and axles, especially if bridges are out.
