East Boundary begins with a moderate climb through thick vegetation. The microclimate changes soon to sandy chaparral, and about half way up this climb (mile 0.4), turn left at the Hazard Peak Trail junction to stay on East Boundary. The Barranca junction at mile 0.9 just below the top of this first climb - again, go straight (left) to remain on East Boundary. After this, a short drop leads to a steeper climb that brings the trail into an open grassy hillside. Several short ups and downs finish at a maintenance tool station - this is the top of the main descent (mile 2.0).

The trail now becomes more rocky and drops steeply and steadily back into chaparral over many large water bars. There is one somewhat sudden right hand corner (mile 2.3), so be alert and keep your speed in check. A long, gradually curving traverse ends at Islay Creek Road. East Boundary can ridden in the reverse direction, in which case the 1.6 mile climb from Islay Creek Road is relentlessly steep and well-rewarded with great views and an undulating descent to Barranca, Hazard Peak Trail, or Manzanita

Disclaimer

DO NOT RIDE EAST BOUNDARY TRAIL past the Barranca intersection during or for many days after rain due to very expansive clay soils. This will destroy the trails tread and the goo does not wash off easily. In case of rain, ride Barranca instead.
