Nice hike, start early (aim for 7ish for less crowds). Park was absolutely packed when we left around 2pm. Could be a nice trail run ;)

We took it clockwise even tho we intended to do it counter, besides that slight hiccup the hike was lovely besides the sense of urgency we had since the park closed at 8. We started around 12:20 and ended around 7:30 with an average of 25 min miles. Only thing would be nice is another bathroom lol

Wonderful route. We started from Gazos creek up. Had lunch in front of the fireplace. It rained during the entire hiking. But the scenery was absolutely gorgeous.

Awesome trail. I started early morning to avoid the crowds( 8:30 am). I went counterclockwise to hit the elevation earlier. There were some spots on the trail that was washed out, but I was able to find my way with the help of AllTrails. Very scenic, beautiful trail. All together, the trail took about 5 hours to finish

I went clockwise and think it was a good choice. Muddy in spots, but nothing dramatic. Great hike to get away from the crowds.

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.
