Greencrest trail is a great warm up, and one of the prime ways to access the rest of Palmer Park. Once you climb to the top of Pawnee ridge, you'll travel down a dirt road that is a reminder of when the park was open completely to cars. As you go down the hill, you might see boy scouts using the field for camping. Continue down, and duck through the fence under the power pole for some really nice singletrack. The trail terminates at Lazy Land.
