Barely an hour’s drive southeast of San Jose, Henry W. Coe State Park – the largest state park in northern California - protects and preserves 87,000 acres of scenic hills and mountain ridges. This wild, largely undeveloped park welcomes backpackers, equestrians, mountain bikers, day-hikers, and anyone seeking solitude in a nearly untouched setting. Part of the Diablo Range, the park is an amalgam of high ridges, plateaus, and both narrow and open valleys. Henry W. Coe State Park sprawls over 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. After a rainy winter, wildflowers bloom in profusion from February through March; by April the color is rampant. The landscape is rich with blue lupine and orange-yellow California poppies, bright yellow gold fields and delicate baby blue eyes. Mariposa lilies, larkspur, blue dicks and Ithuriel’s spear show themselves in late April and May. The variety and richness of the flora attract visitors from miles around. The park is open year-round for hikers, mountain bikers, backpackers, equestrians, car campers, picnickers, photographers, and people who simply like to visit parks. Hot, dry summers bring highs above 90, cooling to the 50s at night. Hikers should carry and drink plenty of water, even on less-strenuous trails. Winter is wet, with highs in the 50s and lows in the 30s. In winter, seasonal creeks can overflow and become dangerously impassable. Spring and fall are the most temperate and enjoyable times to visit. Prepare for the variable climate and rugged landscape by dressing in layers. Dogs are allowed in the main campground, paved roads and one trail that connects the Visitor Center to the parking lot off of E. Dunne Ave. Dogs are not allowed at the Hunting Hollow or Dowdy Ranch entrances or on any other trails within the park.

This was a tough one. We had to take a few breaks because those hills are not to be messed with. Lots of trial users near the beginning and end of the loop. Bring lots of water or a filter to replenish at the little horse troughs.

Mile Trail was extremely poorly maintained, overgrown with rampant poison oak, and poorly marked — to the point that we got lost and ended up in a very dangerous situation climbing up a near-vertical hill. If I hadn’t been able to track our location via the AllTrails map, we would have had to turn back and abandon our backpacking trip. This trail is not safe. Springs Trail and China Hole Trail were better marked with pretty views, and these I would recommend — but otherwise the landscape was dry dirt, weeds, rocky river beds, and plenty of poison oak. I will not be returning and recommend others avoid it; there are plenty of other beautiful state parks in California that offer a better experience.

Very few traffic. Enjoyed it!

The challenge is back to you Ryan Hester! This loop was a great way to find some isolation and solitude. I saw only 4 other hikers. The trails were clearly marked and there was more shade than I was expecting. Plenty of sun though too. I wish there were more single track trails rather than dirt roads which made up most of the trail.

We did this hike in June. There was plenty of water available along the way. We started off from Coe HQ and went down to China Hole. We then followed the creek east about a mile to meet up with the Willow Ridge trail. The water level was pretty high due to the rains this year and we had to cross the creek 7 or 8 times in just a mile. Once you get to the willow ridge trail it is pretty much straight on a single track trail with lots of poison oak to watch out for. There was plenty of water from the spring in a trough about .3 miles from the Willow ridge campsites. We started the day at 1 pm and ended up getting to Willow Ridge about 8 pm. Willow Ridge was beautiful and had great views of the rolling hills as well as some cover under the trees. Everything up to this point was what I’d rate 5 stars. Nice scenery, good water availability, relatively shaded and a challenging hike. The second day we started off to Mississippi lake around 10 AM. After about 2 miles on the Willow Ridge trail you meet up with the fire road that will haunt you for the next 5-6 miles. There’s absolutely no shade, and the fire road follows the crests of the hills constantly going up and down in elevation. It was around 90 degrees that day and it was absolutely brutal being that exposed. Once you finally reach the lake and there’s a fork in the road where it loops around the lake you want to go RIGHT. There is an outhouse (No TP!) and a clearing in the reeds just down the hill from the outhouse where you can filter water. Be warned that although this is a lake the water tastes like it’s from a scummy pond. We camped about 200 feet past the outhouse on the other side of the dirt dam. We did the return hike ~13 miles the next day. It was even hotter at 95 degrees and we found ourselves cursing the completely exposed fire roads. All in all I gave this 3 stars because the fire roads make it extremely difficult and potentially dangerous to do in hot weather. If you’re planning on doing this hike in the summer time be prepared with heat umbrellas or protective clothing and be aware of the signs of heat stroke. In cooler weather I’d give this 5 stars. Make sure you bring a tick key and bug spray as there are ticks all over in Henry Coe.

In the summer this trail is enjoyable but signs are everywhere such as dead flowers that tell us springtime is the best time to go. In spring this would easily be a 5 star trail. That said frog lake was pretty and idyllic and it was an enjoyable hike.

Pretty good hike. No sight of tics. Did it clockwise - two intense uphill parts but the rest isn't too bad. Take water and sun hats/sunglasses.

Doesn't necessarily require 3 days and 2 nights It can easily be done in 2 days 1 night if you are fit and have a light pack.. Although it would be best in early season. I did it Fourth Of July weekend and it was pretty hot and water quality was low. Also trails can be hard to follow at North east of the park due to low foot traffic that side of the park gets.. But still amazing as always. Love Coe.

Anyone up for beating my time? Would love to see someone put up a faster loop. Great workout, but not particularly impressive otherwise (except for the steep grades)

I had a terrible time. I thought it was a great hike don't get me wrong but about 2 hours in, the tics came out to play. I tried to push through it but I came to an end point. I found at least 40 tics on me and at about 5 miles in, I decided enough is enough and I turned around. The hike I like but the tics totally ruined it for me. Don't go over the summer..

Pretty good workout- we started late this time- around 6:30 and finished around 4:00 pm. It got insanely hot. Creeks have water and we could filter and refill. We were each carrying 3 litres and we ran out. So please refill. Did it counter clockwise this time- the last mile is easier this way. But overall no matter which direction you take , it is brutal.

This trail is fun, easy, and rewarding! Beautiful views out over the Valley. A table for a picnic. Wear long pants, as it can be somewhat overgrown.

Hiked this June 1st. Warm day to start but ended hike in thunderstorm. Be prepared. Took 3 liters of water which was plenty. Hiked down China Hole Trail and out on Madrone Springs which switches back and forth along the stream and then a quick 1,000 foot climb. Need to be in good shape but the wildflowers, China Hole, and beauty in spring worth the effort.
