beautiful!

super easy, great for kids and a beginner trail

Love this park
It’s perfect for my three year old to run around and I get my exercise too

Fun little trail. I do this weekly with lots of loops and switchbacks to add to the difficulty. Street parking is free. Lots of shade.

Easy and pretty trail, safe and well populated when I was there

Free open parking along the road

Such lovely weather for this today: sunny and 75, perfect visibility. At the top of the trail I could see Catalina Island and a strip of ocean in front of it. Took a double running stroller with my twin toddlers--there was a spot I had to turn around and bring it up the trail backwards over huge tree roots, and there were some deep cracks from the rain on the sandy trail that were tough to get over, but over all it was doable. There's a lot of uphill, but it was so fun.

very welcoming to all, nice view, ample parking(must pay to park inside, outside is free) not many people on the day I visited which is always a plus in my book. small play areas for kids, plenty of benches, tennis courts.

Nice easy trail with one big hill on one side of the park. You can actually go up the hill three different ways (long easy on the backside, moderate switchbacks up the front, steep uphill right near Rosecrans Ave.) if you want to up the difficulty. Walked with 4 kids (ages 8 and 6) and they loved it. Most of the way is nicely shaded. There is a great play area for the kids to blow off some steam after.

Great trail to get back out there with quite a bit of shade, plenty of places to relax if needed, plenty of restrooms, open quite late, and nice views. Park on the street if short on cash.

Its a great view. And most of all, basically in my backyard

Nice and shady. with beautiful views of nature

Beautiful well kept park. Nature center seems intriguing. Great for walking, picnicking and family gatherings.

Did in a rainy day because it was close. But the trail is in bad shape and rough from biking. Lots of bikes! Views nice. But graffiti and trash made it feel like bad urban.

We went here a few weeks ago. It was a great little hike and the kids really enjoyed the playground afterward. We'll be back!

Makes for a very well shaded trail in the shape of a U on the perimeter of Clark park. There really isn't a trail along Rosecrans avenue although one can make up their own trail. The "U" measures at ~1.6 miles. Hit it 5x, 8 mile run and done. Not bad especially for locals who can walk to the trail.

Come here often with my dogs, really nice trail, well maintained and nice scenery. The start is on the street side of the park- far east in the corner and up the stairs, but there are many other entry points.

easy n kids loved it

It is a flat trail with a little hump at the start....entrance to the start of the trail is across the baseball field. Good for an evening walk.

Very cool park. Lots of BBQ and picnic areas. The trail has many access points. We started in the back and followed the trail upwards to the lookout over the baseball diamond. Slight incline but overall was easy. My 3 year old loved it. Dogs on a leash are allowed but no bicycles on the trails. Lots of shady spots throughout the trail. Nice pond in the middle of the park as well.

This is a cool little loop around the perimeter of a residential development in the West Coyote Hills area of Fullerton. It contains a modest incline and is good for mountain biking, running or walking the dog. The Castlewood Trail is also part of the much larger Fullerton Loop.

This is a short little trail around the perimeter of the Clark Regional Park. It's pretty run of the mill, but there are a few good vista points and it's a great place to take the dog to get some exercise.

Easy little hiking trail that is dog friendly. It's short but you could do it twice. I went on a monday afternoon and there was hardly anyone. Lots of bunnies and squirrels to see, good for kids. Parking fee if you park in the lot but if you pass the entrance and park right on the street, it's easy/free.
