Following a forest fire in October 2019, the Wilkinson Memorial Trail was rerouted near the summit of Sugarloaf Mountain to avoid steep, eroded, and dangerous conditions. The new trail route follows the fire break created on the eastern side of the mountain, in response to the fire, so that the trail no longer crosses the summit. The summit could be reached via an out-and-back side trail (a section of the former trail route).
In July of 2020, New York State Parks closed the out-and-back trail to the summit of Sugarloaf Mountain. This closure is in effect indefinitely to preserve the rare rocky summit grassland community.
