I just finished a modified version of this hike starting at Castle Rock and staying at Lane trail camp. I agree with the others who have commented on this. You need to carry at least 2.5L of water. If you are taking my route, which is ~18 miles each way, then you should carry up to 3L when you fill up at Waterman Gap as there is no water source at Lane Creek camp. (I had to go an extra 4 miles round trip to get water once I camped there). Overall it was just a long hike. Some parts were really nice and others not. If you want to do a high mileage hike I'd would suggest doing Berry Creek falls trail 2x.

Did this loop as a day hike ;)

Great loop if you fancy a challenge! Anti-clockwise seemed the best option - the early section is exposed so you get to do it in the cool morning sun if you go early.

Three stars for me as I’m not sure that I would do it again, except to test my fitness or as training in future. The anti-clockwise section from the start to Slate Creek was perhaps most enjoyable due to the varied terrain. A few km after Page Mill Site the terrain and scenery tends to become quite monotonous (but still beautiful!) however the final section from Big Basin back to the start fully tracks the road which takes some of the fun out of it.

In July there was water at Slate Creek, Iverson Creek, Fall Creek & Boulder Creek. Starting with 2.5l I comfortably made it to Boulder Creek before refilling with 2l but should have refilled 2.5l.

I definitely recommend this loop! Only reason it’s not 5 stars is because about 25% of it is along roads, so you’re hearing cars instead of the wild.

I did this loop over 2 days, camped at Waterman. I started from Portola National Forrest, which by the time you get on the loop trail probably adds at least a mile. Totally I’d say was 32 miles and I perfect split 16 and 16 each day from where I started. Note: where this map says start/finish, you can’t park! So unless you’re being dropped off you can only park at one of the 3 national forest.

Portola was a good place to start, less busy and easy to park at than the others. I hoped on the trail and headed towards Slate creek. This is a nicely little couple mile section to get the legs warm. After you pass the slate creek campground, you take on the steepest terrain this whole loops overs. It’s a good hour of continuous steep terrain, great to tackle your first day. After that is rolling hills and a since change of scenery from tree covered areas, to open grass pastures and hilltop views almost to the ocean. The last couple miles to Waterman you’re on the Skyline to Sea trail along the road. At one point you get into some rocky areas with some incredible views.

Waterman Camp: permits required, but didn’t run into any rangers along the way, and there was plenty of room at the site. Running water, which was the only place I refilled. There’s a stream by Slate creek, but not much else for water from Portola to Waterman. Only downside is you can hear the road from the campsite, and those windy roads attract lots of people racing their cars and bikes.

Day 2: I was pretty sore from the 16 miles on day one. This was by far my longest hike yet (prepping for Whitney). Again, another day of rolling hills and great change of scenery. You get into more of the redwoods in this section. I woke up to rain that morning and hiked the first two hours in a nice steady mist, but there was a majestic layer of fog throughout the forest. From Waterman back to Portola where my car was, I think I saw 2 people on the trail and both were within the first 30 minutes of leaving camp. This is what I came for! You’re still along roads, a lot of this section is along the road going into Big Basin, but it’s beautiful none the less.

I was pretty beat up towards the end, I probably should have just used my running shoes, but this was an awesome 2 day hike. The elevation gain throughout is pretty substantial and the miles will test you. I ran the SF marathon a couple years ago (sub 4 hours)... and I think this loop was tougher for me both mentally and physically! I did this loop for the workout and that’s what I got! What’s nice is all 3 campgrounds are spaced out almost exactly by 10 miles, so it’d be easy to split this up over 3 days as well.

Great way to see a wide variety of the open spaces and trails in the peninsula. This trail takes you through five different parks, and it's nice that it's a loop so you don't have to shuttle cars around.
