Strenuous 15-mile hike captures the wild essence of Henry W. Coe State Park, southeast of San Jose, California. This is Henry Coe the hard way: 15 miles with over 4,000 feet of ascent and a chance to test your legs on the "Short Cut" -- consensus pick as the San Francisco Bay Area's toughest trail. 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. Make no mistake: this is a very tough trek and you'll need all the cheer you can get.

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.
