Was in the area and looking for a place to take my dog for an off leash walk and this was it. It…read morewas after some rains, so lots of muddy spots on trails. We did a nice mile and a half loop, perfect length for my small dog. I got parking, but there are not many spots, so that could be an issue. I also didn't see any bathrooms, forcing me to figure out alternatives. Rolling hills, but nothing too bad. Some native plant restoration work was being done and everybody I passed by was polite and pleasant. The trails are very exposed, so I would limit my hiking here to days with more mild weather, but it wasn't busy a really nice change of scenery for me.

In the past few years, I've explored many different entrances to this open space. Surprisingly,…read moremany of the entrances are close to or even on private land, with an easement. For example, the entrances nearby Walnut Avenue are often interspersed among largest estates. Generally, the trails are well marked. But not always. And sometimes trails do not show up on the official Park map. Having said that, this is a delightful Park with tons of interesting trails. In most areas there are no facilities or water, so keep that in mind.

First let me say that this trail is far from uniform from one part to another. The northern portion…read morenear Concord COULD be scenic if all the encampments and trash was cleared out. This portion, miles 0-4, was recently repaved However there are no restrooms along this section. Miles 4-8 can be very congested with people walking dogs and pushing strollers. Even sections with "pedestrian only access" are largely unused and the multi purpose trail has most of the traffic. Miles 8-14 are not very scenic. Mostly backyards. Lots of cross streets making cycling less enjoyable. Miles 14-20 are more backyards and several more cross streets. There are a few narrow bridges over small creeks. Miles 20-24 are fairly industrial. The trail is much cleaner and better patrolled from Walnut Creek south. North is a totally different story. One park employee told me he thought I was brave to ride on that section of the trail. Not a place for families for sure.

I absolutely adore the Iron Horse Trail. Been walking and running this trail for many years now,…read moreand it's still just as beautiful as the first time that I stepped upon it. The entire trail measures roughly 32 miles one way and stretches from Concord all the way to Pleasanton. I've only been on the Concord/Pleasant Hill/Walnut Creek side, but my dream has always been to traverse the entire trail in increments over time. The trail is a flat paved path that will take you through a plethora of parks, connecting trails, under freeway overpasses, and through a few tunnels. There is always greenery on the trail, no matter what season it is. It's not particularly challenging and there aren't any inclines, but it's perfect for a casual stroll or a long distance run. At any given time, you'll witness people walking their dogs and pushing strollers. Many people train for marathons and long distance running here. It's a wonderful family friendly and community driven trail that feels very safe. What I enjoy most about traversing this trail are the stunning views that I'm graced with every single time that I'm here. This trail has truly exposed me to the beauty of Contra Cost County. So many gorgeous wild flowers and lush vegetation. An ample amount of rampant wildlife. The most beautiful and peaceful community parks. Entrancing Views of the nearby communities. You will get to experience all of this along the Iron Horse Trail. People are so friendly on this trail. You tell get a sense of community here. There are also many bikers that use this trail too. There are several rest benches and doggie pooh pickup stations. You always see a trash can nearby to encourage cleanliness. There are mile markers on the main trail, and a second path that also runs parallel to the main path for most of the duration. It's a great place to clear your mind and to breathe in the fresh local air. Walking down this trail has gotten me through some tough times in the past, and it's filled with so many memories. So grateful to have this local gem practically in my backyard.

Really, join me! We'll make it work! We'll live on thistles and spring water, and we'll dance with the butterflies! Oh, never mind, we need beer money...but do check out this trail...I pretty much guarantee you'll love it. Here's my loop: West Blithedale trailhead, up Old Railroad Grade to West Point Inn, past the Inn to Old Stage Road trail, down to Pantoll campground, (through the parking lots) to Coastal View trail, ride Coastal View all the way to Highway 1. Then turn left, ride carefully on Hwy 1 to the Pelican Inn, and have your friend guard the bikes while you get a pot of tea to drink out on the lawn. Then lug your tired rear up Diaz Ridge trail back to Mill Valley and don't hate on me for getting you to a place that's downhill from where you want to be. Alternate plan: Get your friend's husband, who has a truck, to pick you up. Say yes to hitchhikers 'cause that might be you one day and you think you know them maybe a little. But I guess I should review the trail itself: Coastal View is absolutely magnificent. The word 'magnificent' is not an exaggeration, which I am prone to, but not in this case. Single track (but not the scary next-to-a-cliff-you-might-die type of single track) that progresses from wooded bits near Pantoll, to an exposed path, to a Disney-couldn't-design-a-trail-that-looks-this-good segment that winds through some low trees (duck! you might get wet if it's misty), then out to views of the coast (or the fog, depending on your luck). Go with a friend so you can keep saying, "Oh my gosh! This is great! And there's no one on the trail!"* Tons of wildflowers in the spring and great photo ops if you're into that--I am always so blissed out that I forget about photos. Bonus photo op at Muir Beach overlook right off of Highway 1. *OK, you may see a few others on Coastal View trail. On my most recent ride, we saw a single runner (that's it!) from Pantoll to Hwy 1. That said, don't rush it, savor it. Look out for bunnies. PS Yes, you could hike this, too, but I never have. I'm sure it's just as nice on foot. PPS the only place you might lose your way is just past Pantoll, but watch for the signs and I think it is clear.

With COVID-19 illnesses rising, I choose an 6:00am start to avoid crowds. Easy parking near John Muir Hospital (thank you, Jennifer N for the tip). Headed south to Alamo for about ten miles. With a new gravel bike, I had the options of riding pavement or hard packed dirt. It wasn't as crowded as the Iron Horse Trail further past Alamo. Just a few runners. Not challenging at all, which is good. It was a relaxing ride with my new toy!

The Ygnacio Canal Trail is one of my favorite walking and running trails in the Walnut Creek area!…read moreLocated in the Ygnacio Valley hills, this trail extends about 7 and a half miles from Citrus Avenue in Walnut Creek to Heather Farms Park. This trail can be accessed from several different residential streets in Walnut Creek and it also intersects the Contra Costa Canal and California Hiking and Riding trails. There are loads of beautiful scenic views and all types of different wildlife present throughout. The trail runs parallel to the Ygnacio canal where you can view the adorable ducks swimming alongside. The trail is easy to moderate, given the rolling hills at the beginning near Citrus ave. The trail passes through a few different parks and golf courses, one of which is the Arbolado Community Park. I sometimes park my car at the park and continue on the trail from Arbolado blvd. I haven't yet been able to finish this trail in one sitting since it is 7 miles long. However, I have traveled along the entire trail to its' end at the beautiful Heather Farms Park. The people on this trail are always super friendly. This trail is shared use, so people walk, run, and ride their bikes. At it's highest point, you will capture the gorgeous views of Walnut Creek and Mount Diablo in the distance. Lime Ridge Open space can also be accessible from the tunnel overpass near Ygnacio Valley Blvd. In the summertime, this trail can be sweltering in areas that aren't shaded. I've seen ducks, squirrels, and even cows roaming around in the hills. If you are looking for a new trail to conquer in the Contra Costa area, add this one to your list!

There's lots of parking available here, but be careful if you are parked across the street.

Keep in mind there are no facilities in the park. At least, I have never come across any. On the other hand, everything is free. So overall, a good asset to our community.
