Henry W. Coe State Park sprawls over more than 87,000 acres of high ridges and low valleys southeast of San Jose. It once belonged to a rancher named Henry Willard Coe; his heirs donated the ranch that would become the state park bearing his name. The park has few amenities, but has abundant trails for hikers, equestrians and mountain bikers. The hike to Mount Sizer goes deep into the heart of the park, where the views from the heights seem to go on forever (occasionally the snow-capped peaks of the Sierra are visible on clear winter days). To hike into this remote country is to see it as it stood for thousands of years before the first European settlers arrived. Some of the hills are scarred by wildfires of recent vintage, but the sight of green reclaiming the blackened landscape can't help but cheer you up.

This is a good one! Completed on 5/19/18 and this will kick your ass. We did it clockwise and it starts out nice enough but once you hit the short cut, it gets pretty serious. This is an intense climb so make sure you're well prepared for this. I clocked in around 1500ft of gain. After this, it's a nice walk on the ridge. We cut down Jackass Trail, though, wouldn't really recommend this route, its super overgrown right now and we found lots of ticks on us after that stretch. The climb on Poverty Flats is pretty rough too, tough way to end an already long hike. I should have filtered more water at China Hole but opted not too. This is a solid hike but as long as you're well prepared, it's nice and challenging. Enjoy before it gets to hot!

Hiked on 3-10-18. 5 stars... maybe because it was raining and the wildlife was out, there was only 3 people on the trail (beside a few backpackers in Poverty Flat). I completed going clockwise, heard frogs at frog lake, a fox up on Blue Ridge, a rabbit, two herds of deers, multitudes of California Newts. The Big Berry Manzanita are amazing as are the Madrones. Flowers were out. Anyways this hike was a gem in the rain with an umbrella. But a lot of elevation gain. This hike took me 8 hours, and ended in the dark after a great sunset.

I did this trek on Sunday 3-12-18 and unfortunately I did it backwards. So I can not say I have completed the "short cut" It was a really nice hike in 65 degree weather can imagine it being much hotter I would melt away. It was long and intense for me and I hike every weekend. I took the Jackass trail from Poverty flat to Blueridge (remember I started at end) Going down the Short Cut is really rough on the knees..... I much prefer going up it. I will be back to do it the right way.... It is very peaceful and lightly traffic, just how I like it.

Tough one. Budget at least 7 hrs.

A couple of strenuous climbs, but completely worth the view you get along Blue Ridge Rd. There are plenty of hawks to keep you company. The creek is also beautiful even in the summer and worth poking around if you have time. Most of this trail is downhill and a bit hard on the feet - I had to run the steeper parts. Finished in 6 hours, "short cut" took me 36 minutes.

Hiked this in 90+ degree weather. Did it in 7 hours out of necessity, but now I'm dead.

This trail takes you to the bottom of the valley, to the peak of mt. sizer, back down to another creek bed, and then back up to the starting point. Drank four liters of water and wanted more. I bought the fourth liter at the advice if the rangers, and that saved me. 5 stars, but I do not recommend going in the summer.

I consider myself an occasional hiker 6 to 7 times a year, maybe 10 miles at a time. I have hiked almost all the other popular day hikes in the bay area. I hiked this Monday about 80 degrees weather. I was contemplating climbing Mt. Whitney and was checking my endurance. This was a killer. I somehow ended up hiking 17.5 miles with a few side trips. The "shortcut" took me 1 hour 30 minutes, twice my age. I did take jackass trail it is passable during the day, although I counted 4 trees fallen over the trail. There is some poison oak along the route that one can avoid if they are careful. The Jackass trail is overgrown at some points and would be impossible to follow during dusk or at night. It took me 10.5 hours to do 17.5 miles. The views were good, but I have seen better at other hikes in the area. It is a good training hike to test your stamina. I concluded I am not ready for a day hike up Whitney, maybe I could do with an overnight and more training.

Did this the second time, but camped at Sada's spring this time instead of dayhiking all of it. The site there is perfect for a single tent, with a good spot for a hammock. Going up the 'shortcut' in 90 deg weather in the afternoon with camping gear may not be the best idea, I discovered.

It's really tough. We spent 9 hours to finish this, including multiple rests and crossing 3 creeks. Be ware to be get wet in the creeks during the spring time. But once you have done it, the only feeling you have is proud.

We went in the reverse direction, which got cutoff out of the way earlier in the hike. I strongly recommend adding the additional couple of miles to take as many of the side single-tracks as possible: flat frog trail, jackass trail, china hole up to manzanita point, either springs trail or forest trail. you'll encounter more poison oak, but being off of the roads is worth it, and it's only an extra mile or so, with no additional elevation to speak of. Poverty Flat rd. to finish is a bit brutal.

The is one of the most challenging hikes in the bay area. It is not overly long but incredibly steep and remote. fantastic views of the Henry Coe back country. Most probably you will not see anyone once you leave the visitor center. Go do it!

The Blue Ridge road / trail has some of the most beautiful views in the Bay Area. Note that Mt.Sizer is not where the free park brochure's map indicates. Also, if you're hoping to pick up a good topo map at the HQ, it may not be open if you get there early (I didn't check beforehand; I got there around 7am and it was closed). There's a decent amount of shade on most parts of this route, and overall, was a day well spent.

This was our first hike in Henry Coe and this guide was very useful- thank you! The hike was challenging but we had cool weather, making it very enjoyable.

Several uphills and downhills, great workout!

I've made it a point to find the cruelest and punishing hikes in the Bay Area and this one tops the list. Mt Sizer is a great tune-up hike for week-long backpack trips in the Sierras and a true test of your will and stamina. And now that I'm more familiar with the many evil and unbelievably steep switchbacks up "the shortcut" and the last punishing "climb out of Poverty" , they no longer intimidate me. But I do respect them and the many other steep hikes in Henry Coe. And since its good to "share", I look forward to hearing my friends swearing a blue streak at me on their first attempt at this hike.

Thanks for the guide - we knocked this out in 8 hours - creek was dry and we battled mosquitos (Oct). A great hike - very strenuous. Did The Shortcut in my age so it felt very rewarding.
