Creds: AllTrails Pro for accurate offline GPS location and miles real-time tracking. Clockwise, 14.5 mi and 2,585’ El Gain. Parking $10. Started ~10:am on Thursday 3 January. Unusual to have tons of solitude in this park. Gorgeous weather day after rain. Trail conditions excellent.

There’s currently a minor detour to Sunset that is very well signposted. Does not significantly change the walk. I set off around 16:30 on a day when it was 30C+ in the Bay and it was very cool. Finished up the whole loop in a little over 3h at a steady pace uphill and jogging on the downhill sections. Anti-clockwise is ideal for a later start in the day as you get the uphill out of the way early (in shade) and top out into some afternoon sun before gently descending down Johansen Road which is a wide road and also fairly well shaded with occasional breaks for sun. Where Johansen joins Creek Road there’s an absolutely stunning tree house very visible from the road. Shortly you descend to Berry Creek Falls at the lowest point on the trail which threads around some beautiful old growth redwoods by a stream for a few km before a fairly steady uphill back to the Visitor Center. Highly recommended with very little to say against it. A few more exposed sections would be nice but the terrain is already varied.

I spent two days, and extended the loop further south. With a backcountry permit, parking is required at Jay camp, just a short walk to headquarters. I was able to enjoy the redwood loop both at the beginning and the end of the trip. Day one went up skyline, then hollow tree trail, circled around to Sunset Camp. Great location to set up the tent then enjoy all the remaining daylight at the falls along west berry creek. Then day two takes you by the falls again, soaking in the morning sunlight of the trails. I continued to Berry Creek falls and stopped for breakfast. Had the place to myself on Tuesday morning. Plan to spend all the time you can along this trail, every step is time worthwhile. I then continued south on skyline, took McCrary Ridge up, then Howard King to bring me back. McCrary is a 1,700 ft climb in 3 miles, and exposed for a good portion, be prepared. Ocean views along most of the trail. In all, I extended the total to about 20 miles with about 4,000 ft. Great alternative to the full Skyline to Sea if you are limited on time or don’t want to coordinate a ride.
