Passed the slide in the second week of May. You can pass after 6:30 pm when the construction crews go home or very early morning before they start. We threw the panniers down a 100 ft cliff and slid down on our butts with rope and bike. Crossing was difficult with carrying bike & panniers while many of the rocks were unstable. Not real safe. I was wearing Vibram five fingers which did not help. We then found a rope on the south side to climb up while carrying the bikes and panniers.
At the time the slides was still active. If any rocks come down jump in the ocean! We were told that it was a federal offense to cross the slide. $300 ticket if caught. Not sure how much is true since there seemed to be a lot of non or misinformation approaching the slide. However, we were told that town people often cross also. The good news, the road is pretty much all yours. Very few cars compared to normal so the best time to bicycle but cross at your own risk!
Stayed at Limekiln campground not too far from the slide. We rolled in to a nice hotel $99 a night, Ragged Point with nice restaurant I think maybe 15 miles from the slide because it was dark.
