This is a great path to ride your bike fairly easy. my kids have done it from start to finish

Trail runs along 101 highway in between mountains and the Pacific Ocean. Beautiful view while pumping adrenaline rush of riding next to speeding cars.

This is one of our favorite rides that we have done a number of times over the years when vacationing in the Ventura area. We've always ridden this trail in the summer when inland temps are sizzling, but you can count on cool, refreshing breezes and beautiful ocean and coastal views on this easy trail.
The official trail from San Buenaventura State Beach to Emma Wood State Beach is only 4.1 miles long which is why we extend it. Don't stop at Emma Wood! Continue north on Pacific Coast Highway. I know, you have to ride on the road with only a white stripe to separate you from the motor vehicles, but it seems like the only traffic is the occasional lumbering RV slowly headed to their campsite along PCH. If you take my advice, you'll definitely burn more calories and be rewarded with spectacular views of the Pacific, gawk at multi-million dollar beachfront homes, and envy relaxed vacationers enjoying their RV's.

If you ride this trail, do it in conjunction with the Goleta Beach Trail or Maria Ygnacio Bike Path since it's so short. The locals must love this since for the most part it's quiet, away from roads, and leads to the beach. It seems ideal for the neighborhoods that back up to it for the last couple of miles. If I lived there I'd probably be on it most every day headed for the beach!

We rode this trail between the marina and bird refuge a few years ago. The photo op highlight was peddling our bikes between the rows of giant palm trees for that stereotypical California beach scene, but for a couple of native southern Californians palm trees are no big deal. In addition, the ride is so short it just wasn't worth getting the bikes out of the SUV.
This trail feels most appropriate for tourists, walkers, joggers, skateboarders, and vendors renting those quadcycle things to families.

Way back in June of 1998, the Los Angeles Times had an article entitled "Joy Rides - 10 scenic bike trails for real people." Coming in at #8 was "The Milk Run." It was a 16 mile round trip through the Ojai Valley starting at Foster Park. Being the real people that we are, my wife and I rode it a year or two later during a vacation to Ventura.
Today that trail is known as the Ojai Valley Trail, and from the photos on the Rails to Trails site it looks just as beautiful as twenty years ago and appears to have had some nice upgrades added too.
I recall lots of trees, a rural atmosphere, a gentle incline, and being able to pretty much coast much of the way back to Foster Park!
(BTW: I've racked my brain and done some research, but I can't remember or find why it was referred to as The Milk Run)

This trail has two parallel sides. We parked at West Creek Park – a lovely park about a mile south of the northern most trailhead on the western section. This beautiful park had nice restrooms, water and plenty of parking. The trail is often lined with a white fence passing through some residential and some commercial areas. The western section is less scenic than the eastern section and passes through more commercial sections. One of the good things about the western section is that it passes a shopping center that has the best breakfast restaurant in Santa Clarita: Eggs N Things. The western section connects to the South Fork Trail and that connects to the eastern section of the San Francisquito Creek Trail so you can easily do a loop ride. The eastern section ends at the same road (Copper Hill Drive) as the western section. It is a short distance over a bridge to connect back to the western section. In between the two segments is dry river bed. The eastern section is much prettier passing through a residential area with greenery planted on the side. Going north on either section is slightly uphill, which means downhill going south! There is a separate pedestrian path and two-lane bike path. The path is smooth, well maintained and very good for running, walking, biking and rolling on anything.

This trail is one of the many beautifully maintained connected trails in Santa Clarita. It runs through basically residential areas with the dry river bed on one side. (At least it is dry in now, in February). I think this would be a more scenic trail in the summer when the trees have leaves. However, there is a certain beauty to the dry riverbed. It follows along the power lines and provides a flat, smooth surface perfect for easy biking, running and generally any kind of "rolling" be it skateboards or roller blades. There is usually a separate lane for pedestrians making it very safe for runners and walkers.

As of the date of this review, the Arroyo Seco is closed for repairs. Most of the entry gates have been chained up. I was able to get on the path and it can be dangerous to anyone riding a bike. The recent storms have caused large boulders to slide down the hill on to the path along with mud and debris. There are also pieces of concrete/steel plating missing which is a hazard. I will post again once it is open.
