Dogs are allowed off leash on this trail, but read carefully the "Need to Know" section. <br><br>For the first 0.3 miles, there is little change in elevation. <br><br>If you look towards the ocean from the mid parts of this trail, you'll notice below the remains of a whole series of parallel roads. These are left over from the 1960s when the area was a landfill. Occasionally volunteer groups search for, and haul out, any trash that has surfaced--along with trash left by careless users. Apparently, some folks worry that, in the next "Big One", a lot of the trash from landfill will be dumped into the ocean. I think it is more likely that the landfill will be buried deeper by the collapsing cliffs above.<br><br>At the point where the trail begins to climb and switches back towards the south, another flowery road/path branches north for about a quarter mile to a viewpoint that overlooks the beach, the Marin Headlands, and Tamalpais. This path ends at a major landslide. You should be careful not to hike out onto unstable land.<br><br>Our High Trail continues climbing past a high paragliding point and on up to where a lot of construction was done to drain water out of the cliffs and slow their collapse. Pipes have been drilled into the cliff. There is a large catch basin that fills with water after rains. A long pipe runs from this to take the water farther down and away from the cliffs.<br><br>From the higher parts of this trail, you have views over the entire Mussel Rock Park, the cliffs above and the ocean below.
Road leads up to where a drainage system has been built to try to prevent the collapse of the cliffs next to the houses above.
