Love this trail but today I saw 4 tarantulas and I happen to really hate spiders so watch out everyone. It is tarantula mating season.

This trail isn’t as spectacular as some more notable national park trails but it is beautiful in its own right. The rustling rolling golden hills that surround you give you a sense of zen with a bright blue sky as a back drop. The trail is hardly trafficked so it is very likely to not come across anyone while you’re on it, personally that is something I can appreciate. As far as difficulty, I’d say it is a bit more difficult than moderate. As someone who trail runs 10 miles, has done Whitney etc., the rolling hills on this trail really give you a good workout. The trail isn’t at all treacherous but the constant change in elevation really takes a toll after a while. Enjoy! :)

Good training for hills and no one else on the trail the whole time. Some areas have a weird smell from the surrounding plants and some parts of the trail are so narrow that it’s probably not good to wear shorts because sharp bushes grow right into the trail and you have to brush them. We saw a nice view of Lick Observatory on the way back.

Fantastic and difficult hike! Probably not the best idea to do it in August when temperature was almost 100 degrees but I figured why not. My GPS watch showed 25.25 miles. The key to doing this during the hot summer is bring a lot of water since there are no water sources, aside from some ponds that should only be considered during life and death emergencies with a lifestraw or something equivalent. I brought a 3 liter hydration bladder and an extra 1.5 liters of water in a separate bottle. Yeah that sounds like a lot but I used every drop of it. One nice thing about the hike is that around the midway point you cross the road that goes up to the top of Mount Hamilton. If you're hiking in a group, and have multiple cars, a great idea would be to leave 1 car at the little parking lot where the trail crosses the road. Then when you get to that point you could refill your water supply with extra water you have stored in your car. Another nice thing about the hike route crossing the road at the half way point is that if you decide you just can't do another 13+ miles of hills you can always hike back down the road to the parking lot for Grant Lake where you started. This for sure was a challenging hike. You have to like, or at least be able to tolerate countless hills. Just when you think hills are finished along come another set, and they don't stop until almost the very end. Feels like going up Mission Peak maybe 2.5+++ times, for those people who like to hike up Mission Peak. I'd do it again but I'll wait till the winter when it's not so hot. Early spring would also be a nice time when things are still green. Oh and watch out for rattle snakes, I saw 4 during the hike. I never saw a single person the entire hike so had it to myself. Highly recommend this hike just make sure you prepare, good first aid kit and many liters of water!

This was a really good trail. I started out in the morning around 9am. It was warm day. Make sure to take plenty of water. In the beginning is mostly climbing up. But wants you get to the top the views are amazing. Lick observatory is visible when reach the top Yerba buena trail. And the rest of the view is just amazing. The Dissent back is nice, some shade, is like you entered a completely different place, so the sights are enjoyable. You won’t be disappointed I’ll say that.

Good for trail running and hiking. The start of this route is at a traffic circle I guess. Plenty of shade along the way. Power lines along the way also, keep watch. Around the 5-6 mile mark you may not see the trail clearly. Follow the route with GPS and you should be fine. Once you reach pavement just follow it all the way to the parking lot. Good run. On a 75 degree day with a breeze.. it's blast. Very quiet park.

Really beautiful area, refreshing breeze, few hikers, and a very clearly marked trail. There's very little shade, though, so be sure to bring sunscreen. I went clockwise on the first loop and counterclockwise on the second to avoid the steep elevation. It was still challenging for me, but that really helped.

would probably see wildflowers in spring

This is an absolutely wonderful trail, and I recommend it to anyone interested in a rigorous and challenging 10-mile hike. My wife and I took the trail counterclockwise and loved every step of it. The views included a beautiful panorama of rolling hillsides, the Lick Observatory, and in the farthest distance a glimpse of the South Bay. A personal highlight was seeing the remains of and learning about Joseph D. Grant's Pala Seca Cabin (a destination frequented by President Herbert Hoover after his election in 1928) on the edge of Deer Valley. This was a pleasant and unexpected treat to encounter.

Somebody suggested going up Los Huecos Trail, which is steep for 2+ miles with sections over 10% grade. Thank you! Sure beats walking down those loose rocks. Fantastic hike with all variations of terrain. Nice smooth dirt path, muddy in low areas in May, overgrown narrow path near the top, enjoyable descent on Canada de Pala and Halls Valley Trails.

I can’t really tell you about the whole loop because my friend and I went two miles and then turned around and went back. We were supposed to do the McCreery Lake trail, but it was closed due to flooding, so we did Los Huecos instead. What I CAN tell you is if you start at the parking lot and go clockwise, the trail will be all uphill for two miles after the lake. Oh, and the wildflowers were beautiful in April.

Just did this hike, with 2 variations. I took Los Huecos trail up insteal of Halls Valley, and added the Pala Seca loop. Overall very beautiful, lots of wild flowers and not too muddy since it hasn't rained seriously for a few weeks now. Lots of cows next to the trail, they didn't do anything, but can be kind of unnerving. Not sure was to do if they would get upset. Really glad I added the extra loop up there, first there are very nice views of the Observatory and further hills in Diablo Range towards the east, and on the second half of the loop, there is some goergous natural wetland, with lots of flowers, saw a frog and lots of tadpoles in the water. Last part of the hike is not as nice, since it's more like a road than trail, and finally the last stretch you have to walk on the road, be careful with traffic. Overall though, the blooming wildflowers more than make up for it.

Cows and mud, and smoggy views of San Jose through the hills. Fully exposed, so best done on cold days. A lot of gangly, awesome oaks on these hills.

Very nice hike since everything was really green from the recent rains! It was very muddy at parts. I got to see some wild turkeys as well.
