Fullerton Loop - MTB & Hiking Trail

Trail was very fun to ride. Lots of hikers with kids in tow, so be careful and give them ample space when you bike. The route varies in grade, but still fun to trek. Took my hybrid bike and was surprised it was able to ride it.

From a cycling perspective, it was a blast. This was my first time on this one. There was some really challenging ascents and descents so you will need to be in a bit better physical condition if you want to make the entire loop safely. Also, going by yourself may not be a great choice unless youre pretty good on a bike already and have some basic tools with you. I would not consider this a beginner trail. Your average bike may not be the best option since youll need some more aggressive tires, brakes and gears for some parts of the trail. But a decent hybrid or gravel bike will probably do. Mountain bikes are definitely the most popular kind out there. But once youre out there, there are all kinds of fun spots and interesting side trails to explore. Theres even a couple tunnels and abandoned railroad tracks. GPS and the Alltrails app could be your best friends on this one since the signage is hit and miss. Just plan and be careful!!

Happy to see that the trail is still there bring back great memories when I was kid. Best stop to come if you want to get into mountain biking. Or if you want to go on walk with family.

First time going there with my son and his girlfriend a lot of steep hills and up hills. Its a fun trail.....I did fall on loose gravel just as I was going to start to go down the hill .....and to top it off in front of a really cute guy too.

LOVE THIS PLACE! Such a fun local beginner mountain biking experience. Always a great time. A hidden gem worth taking the the time to experience

Its the coolest trail in Orange County for a fun ride. Not super challenging, but has enough fun climbs and downhill sections for a good time.

Clean with different terrains. Lots of shades for hot sunny hikes... I swear it feels like more than 11 miles. Weaving in and out of neighborhoods and parks.

Love these trails! Access to a restroom here and there might be nice.

This trail is a must in socal I had a blast. Watch the videos on YouTube to learn the crossings there is alot.

Cool place to be to CLEAR YOUR MIND AND GET AWAY FROM ANYTHING NEGATIVE. JUST KEEP STAYING HEALTHY AND SAFE!️️

Great views, lots of great space for biking

Great spot for easy biking or walking. Can make a custom route or follow the one on AllTrails. I like the railroad portion. The golf course is cool too and it goes past a lake.

MTB Project did a great job of keeping track of me while viewing the map to make sure Im on the trail!

Always awesome even if its a bit crowded these days. Try week days for emptier trails...

Great mountain bike trail! Good amount of uphills and downhills

Fun, make your own experience. Perfect for newbie MTB riders.

Great mtb trail. You can make it beginner friendly, or you can do the extra stuff to make it more advanced.

Very good trail for both hiking and biking.. lot of loops to try for bikes. Good elevations

Great place to hone your skills for MTB...im just starting and getting comfortable with their trail and its pretty close as well

There is one main loop with a lot of offshoot trails to walk or bike ride. Its funny how youre so close to civilization but can feel like youre a million miles away at certain points of this trail.

Lots of shade, nature abounds. Many more mountain bike evidence on the sides of the trail, eroding the hillsides. Sure could use a good rain to clean things off.

Great place to get a quick ride in. Ive been bringing my son there for a few years now

Good family friendly walk. Great for mountain biking. Alot of downhills. Perfect for beginner mountain biking. Good work out

Great place to walk your dog. Can be busy on weekends. Not at all strenuous. Also a nice place for bike ride, but lots of pedestrians so have to be on alert.

Love love love! So many different trails and plenty of shade for those hot days.

Best in city outdoor hike &bike trail u can do by day &night safely.If Only if u dont go at the busy hour.

I would love this trail more if the bike riders would learn the kindergarten lesson on sharing. But overall a great place to walk, as long as you keep your ears open and plan to spend a decent part of your walk in the bushes, so you can avoid being run down.

Awesome trail. Kinda busy at time. Normally thats okay but during COVID it is a little annoying but it is a great trail.

Best place to ride your mt bike if you are a begginer...as well as an advanced rider.....i love it.....bad thing they dont put signs to mark the whole loop ..you have to figure it out by yourself...

Good trail for beginners and intermittent riders. Trail hard to follow as you cross streets. Not many signs.

This is a fun place to ride, lots of off shoots and some hills.. most are rideable, a few are longer and can hurt you ;) thats the fun.. ooh wait, no going downhill is fun!

Its so much fun I really recommend to do the loop!This is my first time that I did it!!Feels good!!

Im a beginer and recovering spinal surgery its been over 17 years since ive had any type of cardiovascular exercise and imma tell you what i did it tthe full trail. Not going to say it was cake walk... the climbs really did a number on me but i still did it. Walk crawl ride i did it all lmao... good over trails looking to master the jumps some day

Meatball Sub with extra sauce. Youre welcome.

A beautiful, safe location for the whole family. If you walk, hike, run, bike or ride a horse, this place is for you. Come to complete a few trails, or follow the paths around the hills of Fullerton or complete the Fullerton Loop of 14 miles. Parts are shaded, parts are in the sun, some is flat, some climbs hills. All of it is beautiful.

Good path, mix of walking path and hills, but definitely too crowded due to Covid-19.

Great views, great ride. Stretch before you start and hydrate

Great place to start mountain biking. It has easy, medi, difficult

Watch for the bikes and have great hike.

Super fun to bike or walk. Kinda hilly in some areas.

Good trail for hiking, riding, with something for every skill level

Great after-work spin. No major climbs, 11 miles with about 1,000 feet of ascent.

Free parking, beautiful urban backdrop.

Fun place to run and unwind from daily stressors.

Good place for New Mountain Bike riders to learn how to ride

This is a fun walk. Lots to see. I enjoy seeing all plants and flowers in everyones yard.

I love this trail! It’s so nice and clean. Very peaceful! I get a sense of calm and grounded inside. Probably because I’m surrounded by nature. It’s good for bike rides, walking or running. Super pretty especially for being in the city.

Great plaxe for family mtb

Pretty difficult and sorta rewarding. You just be pretty good to make it out without any scratches. Also, pretty confusing so study the map beforehand.

It’s good for bike rides, walking or running. Super pretty especially for being in the city.

Love this trail... the trees provide so much shade and makes walking or riding a breeze.

Love this trail! Go as far or as short as you want. Shared trail with runners, bikes and horses. Well traveled. Crosses roads at times. Mostly dirt, compacted. If you go the full 11 to 12 miles make sure you know the route. It can be confusing in some spots. Mostly flat if you stay around the start of the trail. Bikes get the hills farther down the trail. Lots of dog walking and usually the owners are good to pick up after them. Water station for pups on one section.

Beautiful place to walk and excercise

Lovely trail with plenty of shade and places to rest. Lots of places to start and stop along the loop, if you dont want to do the entire loop.

Extremely convenient, with some single track and great distance 11 miles.

Great place to visit, dog friendly. Just dont let them drink any water thats been sitting there can get ure pooches sick af!

Would be cool if they add public restrooms and water fountain

I am a runner and currently the trail is over crowded. People have not etiquette. I understand social distancing, but when you walk 4 abreast there is no where else for people to go.

Such a variety of terrain, good for all skills levels, just remember, stay to your right

Great trail with fun uphill and downhill and a bit of singletrack if you know where to go!

Good trail for a beginner.

Great place for a run, but arrive early, the place gets super busy after 8am

Nice hike or run or bike trail...

Best trail around. Take my dog there almost everyday

Great place if your are new to biking

Nice wide trails.

Amazing! I love this mountain biking trail!

Great as just a workout too as there are several climbs that really get the heart pumping. Make sure you know where youre headed because the trail has many street crossings and can get confusing.

Its really convenient for a little bike ride after work but man, there are lots of street crossings. Even saw a mountain biker get plowed into once. He was okay but still, be careful out here. Ill stick to the trails away from cars as much as possible.

Loved it. Lots of buddies (dogs) and the trail was very easy. The parking had cool things like mobile bike shops, and a cute coffee little mobile bike coffee cart. At some point you get to a lake. Highly recommended for a chill hike/walk!

I love All Fullerton Trails, this is one of my favorite, doesnt have alot of hills like some others but what a view !!

First time riding this trail, pretty cool. Beginners will have fun with this one, I did .

The trail is okay, but it is somewhat confusing to follow. You will at certain points cross actual roads and have to walk through residential areas to reach other parts of the trail.

Great trail for everyone. You do have to cross streets an neighborhoods as the trail does cut through and link up. Easy to get lost if your first time here, but make sure to look up the trail before you ride

Great training loop with terrain for most skill levels. Its a hidden gem in socal. Trail is a bit torn up with the rains and can be very crowded sometimes. I recommend going around 730-8am for mountain biking.

Another easy walk. Great place to walk your dog. Can be busy on weekends. Not at all strenuous. Also a nice place for bike ride, but lots of pedestrians so have to be on alert. Lots of shade along the trails.

I brought my friends here on Halloween after hiding pieces of paper and telling them were playing slender in real life but instead they found 9 papers that when placed in the right order say J E S S I S G A Y.It feels good to finally be out of the closet.

Beautiful place

Very big running hiking trail. It runs through a neighborhood so you can change the trip every time. Watch out for the roots while running.

A great place for a family walk with a great view.

Great for beginners and intermediates

Great area for mountain biking. lots of trails. Once deep inside the riding area, you wouldnt know youre in the middle of a suburban city. Be careful because there are also horse riders, walkers and runners sharing the space.

Short and sweet mtb trail

Nice beginner / mid level trail for MTB. Ive done this a few times now, pretty cool.

My son and I loved this trail!

Very awesome local mtb spot

Not bad for my first time

My favorite place to ride my Mtb in a wonderful course with good views everywhere...

Need to explore more. A little crowded..

It’s a great MTB trail for the family and beginning riders. Or if you want to stay in shape, this is a great trail. Although I would like more features

Too many damn hikers and people walking while texting not paying attention

Crowded but nice trail in the middle of a suburban area.

Great place to ride or walk

Great trail system. Once you figure it out and know where you are you can make it as hard or easy as you want

I went rucking and followed a map from AllTrails. At 5 in the afternoon on a Thursday it was pretty empty. By 7 there were more bikers, joggers, and walkers.A mix of shade and sun, pine and eucalyptus trees. Trails are in good condition and a variety of side trails and single track parallel the main path in most areas.

Best 4 beginners.... Hiking biking

Great for all!

Very nice calm and soothing hiking trail. Great for a walking with someone or walking your dog, or for those days when you just want to walk alone to clear your mind.

Great hiking locating with multiple routes from easy to moderate.

This trail is close to everything yet feels like a proper forrest. Main path is wide and open for biking and hiking. The trails are easy enough for the whole family.
