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.

Perhaps unfairly, but as an outsider, I tend to view this part of Contra Costa County as, how do I…read moreput it diplomatically...snooty. There are tract homes that are really mansions in gated communities here. You get a pretty good indication when you take the Livorna Road exit off 680 and head toward the hills. There's a convenient parking lot at the staging area, and the walk begins along a tree-laden path that leads into the Shell Ridge Trail. This is where the open rolling hills provide some challenges to the calves. You eventually make it to the most picturesque portion of the hike on the Mokelumne Coast-to-Crest Trail. This is where the residential areas disappear and you're at one with nature...except for the occasional mountain biker. Small mouth was warranted during such disturbances, but they didn't prevent me from a scenic view of Mt. Diablo (photo: https://bit.ly/3hZ96M1). Now I could've gone deeper into Mt. Diablo State Park, but hey, I'm not a rugged mountaineer. Instead I made a turn and precariously made my way downward to the Alamo Trail. I didn't realize I exited the park until I saw distracted people on the path yelling into their mobile phones as they let their dogs do their business. Hey, where's your scooper, sister? I think with more thoughtful planning, you can probably avoid the ritzy people with their ritzy homes. Maybe not. RELATED - Exploring this part of Contra Costa County?

Fairly easy to follow all the markers. I wish they were all marked by numbers but they're not. The scenery is nice and lots of shade throughout the hike. Many of the roads are narrow and slippery. Hiking poles and good hiking boots are important. The waterfall was mini in beginning of December 2025 but there was a steady stream. Entire hike takes about 4-4-.5 hours to finish. Some steep inclines but not too grueling. Pay parking via QR code and a cc.

I followed the All Trails version of the trail which took around 4 hours and was 8 miles. The hike was moderate to hard because there were some steep parts and parts that were rocky and easy to slip. I'd recommend hiking boots. To see the waterfalls I think the best time to go is Jan-early May but that's even pushing it. By May there are still wildflowers, but the brush is starting to turn brownish, and the water is drying up quick. Probably the most ideal picturesque time for this hike would be early March after a rain. I'd avoid it in the summertime unless you live in the desert and are used to hiking in high temperatures.

I was looking to get a morning walk in and a family member brought me to this trail which she typically runs. We parked at the community center off of St Mary's road. Just one of many locations that you can catch the trail. Plenty of parking was available. The 7.65 mile trail runs on both sides of St Mary's road through Lafayette and Moraga We decided to cross over to the other side of the street from the community center and walk towards Moraga. The paved trail can be used for biking and horses as well. The trail towards Moraga has quite a bit of inclines and makes for a good workout. I went 2 miles in and turned around at Rheem Blvd for a 4 mile round-trip walk. Beautiful scenery and lots of people walking their dogs.

This is one of the biggest outdoor public play structures in the Bay Area that I've been to so far.

There are public restrooms, but they need more frequent cleaning during the weekend. I came here on a hot Sunday, and there were a smoothie/shave ice truck and a soft serve truck parked nearby in the swim center parking lot for purchase.

Fast forward to yesterday. We had a restaurant in Albany that we wanted to check out so of course we had to hike first to get our appetites whet. I found a loop I wanted us to try on AllTrails. It's called the Dunn Trail--Monteiro Trail Loop. We parked at the Richard C. Trudeau Conference Center on Skyline Blvd. It was the perfect spot to start. Free parking. Public restrooms (even flush toilets!). If you have a dog, most of this trail is off-leash which I have never seen before. Every dog we saw were well behaved and having a great time. We don't have dogs of our own but I am a big dog person. This particular loop was exactly what I was looking for. It had several different biomes. Despite what AllTrails said, it is not all shaded but it was a beautiful, sunny, windy day. We saw lots of wildflowers blooming. We found there to be a difference between AllTrails and our measurements. AllTrails said it was roughly 500+ ft elevation gain but ours said 1000. That's a huge difference! But I would believe ours over theirs. There were a lot of inclines. Also, their's said it was 3.5 miles but ours said a mile longer. The trails were all very well maintained. We saw gorgeous views, small waterfalls/creeks, redwoods, butterflies--just lovely. It was less busy than I anticipated but we arrived before 9 a.m. We finished by 11. This is a big park and lots to explore. Highly recommend!

Peak My Interest…read more ***PLEASE NOTE THIS IS THE YELP PAGE FOR REINHARDT REDWOODS REGIONAL PARK*** I was attempting to change the name to the proper moniker that included "Reinhardt," but Yelp mods, being the highly regarded sort, somehow decided in their infinite wisdom that they should change it to "East Bay Regional Park District"?! What the what?? 0_o So, that's on me, kids. My bad. Onto the review... A giant ±1,833-acre redwood forest nestled in the Oakland Hills, this park was a former logging site back in the 1800s. Fortunately, there has been a nice resurgence of redwoods to replace those that were cut down. It ain't old-growth, but we'll take what we can these days. The Good: * Free at certain times of year and at certain entrances (more below) * Mountain biking on certain trails (check map and trail signage) * Horseback riding on certain trails (check map and trail signage) * Camping available (check website for info and reservations) * Reservable and non-reservable picnic tables (check map & website) * Restrooms available in parking lots, as well as at some campsites * Nearly forty miles of trails with something for everyone * If you're looking for a moderate ±4.5-mile loop, go to the Skyline entrance and take the Serpentine Prairie Trail to Dunn Trail to Golden Spike Trail, then back to Dunn Trail The Meh: * $5/vehicle entrance fee on weekends and major holidays between April and October, only at the Redwood Gate entrance * Most of the trails are pretty decent, but some are in rough shape due to water damage The Ugly: * One of the few parks I've seen with "off-leash" sections for dogs--which is fine, except you know there's a good majority of dog owners who think they can control their dogs but really can't. We saw a panicked guy chasing his dog down a trail at one point, and who knows when--if ever--he caught up to it. ¯_(ツ)_/¯ Conclusion: Great park with tons of trails and lots to see and do.
