We'll definitely go again because I have a CA State Park Pass. It is a great and somewhat difficult trail. My advice would be to bring cash because there is a $10 parking fee if you don't have a pass.

Finally made it up today! Pretty steep trail at certain spots but the views from the top are breathtaking! Highly recommend it.

The trail is clean and well maintained. The view was worth the work. Trekking poles are strongly recommended for slick downhill portions.

Just hiked this trail. Great trail.. The last 1.7 miles is pretty steep climb. Go slow if out shape and you’ll make it to the top of the summit. Slow will take about 2 hours if you do long trail. Coming down very slippery. Bring poles if inexperienced hiker.

Best trail in SLO county. Or at least it’s MY favorite hike. Bottom half has lots of shade. Top half is quite a bit more exposed. The views throughout the hike are marvelous and they get better the higher you go.

I love this trail. Not too crowded ever, cool breeze most of the time- incredible views, good, moderately challenging (for someone out of shape) trail.

Great view from the top if there is no marine layer! Moderate seems about right. I’m pretty out of shape and it was hard, but my nephew flew up it pretty easy. Can get cold and windy at the top, so might want to have a sweatshirt handy.

We hiked this trail yesterday and the wild flowers were in full bloom! It was gorgeous! The view from on top of the peak was definitely worth the climb. This trail would be pretty hot during the summer months, there is a lot of the trail that is in full sun exposure. The trail it’s self was very well maintained. There are bathrooms (non-flushing) at the parking lot at the trail head. I recommend starting the hike on the left trail head not the one to the right with the bridge. It’s longer but a less steep climb to the top. Lots of poison oak in this area so make sure your are comfortable recognizing it! Day use was $10, and the overnight fee was $25.

We did The Cerro Alto loop yesterday taking the long way up and the short path down. It is a great hike. This trek is not very technical and the trail is really good. I would rate this and Easy/Moderate. It is easy in that, there is nothing difficult to climb through. It’s moderate simply due to the amount of climb. So, go do it. If you are struggling on the climb, take your time. That’s all. You will really love it. The trip down is slippery though. With so much activity the path is broken down a bit to smaller sized pebbles etc. So if you can use some poles, that would help. Bring a lunch and enjoy the top. Really fun hike.

Great hike for one day... moderately steep uphill, with plenty vista points to view Morro Bay from the top

Great wildflowers. Steep at times. Better than sneakers is preferable. Poles would be good idea unless you are very fit or light on your feet. Outstanding views from top but very nice views throughout the hike.

(Now I have to hike down...)

This trail offers a spectacular view once you reach the summit. It also is a fantastic workout and an amazing alternative to stair steppers and elliptical machines!

I love this trail!

I took the longer trail to the summit and the shorter one back to the campground. Both are worth seeing, but I preferred the longer route. Both trails are found inside the campground. The longer is further in than the short trail. There is a $10.00 fee that you can pay before the campground right as you turn off of hwy 41 or in the dirt lot at the back of the campground next to the trailhead.

It is a fairly steep trail, especially the last 1.2 miles to the top. Be sure to have shoes with decent tread on the way down. The loose gravel and incline combine to make it a bit slippery. This last leg is also very sunny. Bring sunscreen or a hat.

We parked at the 41 entrance and ran up the boyscout trail which is quite steep. Went through the tower road where it connected to the out and back of the Cerro Alto Loop. Amazing views of Los Osos, Morro Bay and all the peaks. Diablo, Black Hills, etc....Highly recommended!

Great trail. Bathrooms at the trail head were discussing. Come prepared.

Great cardio workout without the need to run. Terrific views. Good option for preparing or conditioning for a backpacking trip.
Only negative is that the trailhead is in a day use fee area so it will cost $10 to hike the 4 mile loop

Great trail along beautifully vegetated hillsides, with a world-class 360-degree view at the top. This well-maintained trail is rated "hard", but I think it's actually moderately difficult. I highly recommend this very satisfying hike.

This is the perfect day hike. Easy to get to the trailhead from anywhere in San Luis Obispo county, great area to park, well maintained trails, not too crowded, great vegetation and trees. The way up is a good work out but is doable for someone that is in average shape... and the views are incredible.

Great hike, Was a great challenge to get to the summit peak but the view is breathtaking and amazing recommend to any one looking for a good challenge

I'd definitely recommend this hike to anyone looking for something a little harder and more out there then something like bishops peak. Took me about an hour and a half to get to the top and an amazing 360 degree view on a clear day from Morro rock to Atascadero area. Trail is marked out well minus a few spots but using common sense you can figure out where you need to go. Make sure you bring 10$ to pay the day fee or 25$ for camping. Ticks, rattlesnakes and mountain lion warnings posted but that's normal for hiking in my opinion.

Probably my favorite trail I've had the chance to trek in SLO County. The most challenging physically and only recommended for higher fitness levels, especially if you're planning on hiking up to the peak. I took my bike up to the top and it was pretty savage, but the views are utterly amazing. I could see from Guadalupe all the way to Ragged Point. Easily the greatest ocean view I've ever seen. The ride down was an adrenaline rush to say the least but oh so worth the push up the peak. Lots of cool nature views, creeks, etc. I even saw a horny toed lizard when I was up at the peak, which I did not expect or even knew existed out there. Just an amazing place to hike. Be sure to bring at least $10 with you for parking as the county charges to park

Dont let sammi review scare u off seems like he or she is inexperienced and out of shape... i have climbed this with a 2 year old on my back.. it is challenging but doable, check weather, better to go on cool day as there is little shade.. take plenty of water.. maybe some trail mix but no need to pack full meal if ur relatively in shape.
