Getting There

Please note that partial trail closures have been reported for this trail as of 06/30/2020. Estuary, birdwatching, marsh, scenic side trail. Street parking near the trailhead is free. Sea breezes make this one of the few treeless trails that you can hike in summer in Southern California. Located far from the ridges, the flat expanses of the marsh do not, at first glance, seem like much of a place to commune with nature, but once you get up close you discover all kinds of wonders including waterfowl, insect life, peculiar vegetation, and fossils. The trail as reported includes a side loop up Big Canyon, a eutropic arroyo where a pond is becoming filled up due to runoff from blufftop housing. You can lose yourself amid the cattails, bay laurel, and papyrus, allowing yourself the belief that you are far from civilization, perhaps somewhere in the Everglades. Great Blue Herons, American Egrets, and Snowy Egrets stalk the mudflats to the west giving joy to birders who bring spotting scopes in search of waterfowl and shorebirds. Remember that this is "a multi-purpose trail" for hikers, bikers, and slow-moving autos.

This is more of a bike/ running/ walking trail than a hiking trail. The surface is mostly flat, and mostly on concrete (some dirt). This is one of my favorite places to run!... even though sometimes the people on bikes are a little rude. Parking is easy if you get there early enough.

Seems to be more of a bike trail than a hiking trail. You walk behind the trailer park which is not very pretty.

HikingClosedOff trail

We started near Jamboree and a portion of the trail was closed so we took surface streets until we could get back to an open stretch. Besides that it is as described. We also found a park to use the bathroom and went off the trail there too. But well worth it. Bring plenty of water a hat and maybe even an umbrella, there is no shade. But will do again!

I like running this trail, when I need a quick run. I like starting on Eastbluff, either going downhill into the trail or towards the 73 over the bridge. Either way is gorgeous, watch out for cyclist. The trail is marked every 1/4 mile, I like going up to 2.0 mile marker, then turning back.

I have lived in south Orange County for over 30 years and this was my first time walking this trail. It was absolutely gorgeous. And if you’re a wildlife lover, the bird activity is amazing. Various species of ducks, cranes, geese, turkey vultures, and we were also lucky enough to see an osprey.

Great for trail running. Wear a hat! Also I lose service near the trail so download any app programs before. Lastly, be careful when following Apple Maps it told me to go past Back Bay and continue on to somewhere near marina. Don’t listen to that, turn right on Back Bay and there is free street parking at the end near the trail entrance :)

The free parking is quite misleading as the directions take you to a marina spot that is membership only. You find out after someone is a jerk and backs up to your vehicle within 1” of hitting you.

Easy loop that was great for my elderly dog. Probably best to wear trail running shoes with good traction because hills are a bit covered with rocks/loose gravel. Enjoyed the superbloom and really lovely during high tide

Born and raised here so never thought of it as a trail or something to “do” other than just a place to hang out. Fun for a trip with kids by can get pretty crowded now a days.

Rode this loop a few times while staying with my family at the Newport Dunes. Perfect for the single speed mountain bike I brought with me for the trip. Highly recommend this ride if you're staying there.

I guess how you feel about this place depends on how you plan to use it. Could be fun on a bike (track bike) since it is all paved and don't have to worry about lots of traffic. Could be good for a family with young kids since and a stroller would be feasible. Could be good for joggers. I went with my dog to hike and there are no dirt trails, there is excessive debris in the water/plants and there is a funky sewage smell in places.

One side of loop doesn’t allow cars and the other side only allows cars in one direction so it’s a very calming/peaceful walk, run or bike ride. Very flat except in one small/short area. Nice waterway views all along trail.

Really easy trail for all types of activities. Jogging, hiking, walking, or even biking! You can even drive it (one way) for part of it. There is a dirt trail but also a paved trail for bikes. For biking, it is a 10 mile loop and fairly flat. I bike it using a hybrid - any bike will do here. There are 2 steep parts, but it isn't so bad - for the most part this loop is very flat. I don't break out a sweat when I bike it, so it is nice and enjoyable if you just want some fresh air with some beautiful scenery. Watch out for horse poop on some parts of it. You'll see lots of rabbits in the early morning and evening.
