Most Corona del Mar residents think of Buck Gully as a spring trail. Green canyon, running creek, wildflowers along the fire road at the top. That framing has locals ceding late August and September to the tourists at Big Corona and missing the quietest, best-programmed stretch the reserve gets all year. The window between Sherman Library & Gardens' mid-August car show and the Fall Festival that returns to the same lawn eight weeks later is when the canyon works hardest for the people who live nearby.
This is a use guide for that window.
What the trail actually is right now
Buck Gully Reserve is 254 acres of protected canyon owned by the City of Newport Beach, home to numerous federally and state protected species of plants and animals, co-managed with the Irvine Ranch Conservancy. The Poppy Avenue trailhead at 872 Poppy Ave, Corona Del Mar, with free street parking, is the traditional starting point and the only end that offers parking. From there, the single-track runs roughly three miles up-canyon toward San Joaquin Hills Road, with a fire-road extension at the top and an optional return loop via the Bobcat Trail.
The infrastructure most residents walk past without registering: the trail renovation project, made possible by the City of Newport Beach, State of California and the Irvine Ranch Conservancy, included the dramatic placement of four bridges by helicopter, plus re-routed creek-side segments and new drainage designed to keep runoff from eroding the streambed. It is a working restoration, not a passive open space. The City has partnered with the Conservancy to manage the reserve through targeted invasive plant species identification, removal and habitat restoration.
That context matters for how you're supposed to move through it.
The rule set most residents get wrong
Four things trip up locals who haven't hiked it in a year or two:
| Rule | Detail |
|---|---|
| Bike direction | Uphill only, one-way, in effect since October 2019 |
| Dogs | Not permitted anywhere in the reserve |
| Hours | Dawn to dusk, daily |
| Legal trails | Buck Gully and Bobcat only |
The one-way bike rule is the one that catches people. The trail is maintained regularly, including fixing ruts, sandy sections, and cutting overgrowth so the trail is almost always in pristine condition. As of October 2019, this trail is now one way for cyclists, uphill from the Poppy trailhead. If you're walking down-canyon in the late afternoon, you should not be meeting bikes coming at you. If you are, they're breaking the rule.
The dog restriction is stricter than most CdM open spaces. Buck Gully is open daily from dawn to dusk, but dogs are not allowed in the reserve. Not only does the presence of dogs disturb native wildlife routines, but dogs are also more susceptible to snake bites while on the trail. Take the dog to Little Corona or Inspiration Point. Buck Gully is not that walk.
And the "legal trails" line is quiet but real. The Irvine Ranch Conservancy is working to restore the reserve after years of damage due to illegal hiking, so please stay on designated trails. The only legal trails in the reserve are the Bobcat Trail and, of course, Buck Gully. Side trails down to the creek exist because people wore them in, and the Conservancy is trying to close them back up.
The canyon reads like a park. It behaves like a restoration site. Treat it as the second thing, and the first thing gets better every year.
Why the shoulder weeks
Sherman Library & Gardens sits eight-tenths of a mile from the trailhead at 2647 East Coast Highway. Two dates on Sherman's calendar bracket the window this piece is about.
The opening bookend is Petals & Pistons. On August 15 the garden will be open from 8:00am to 4:00pm for the Petals & Pistons Car Show. Come and enjoy the craftsmanship, both mechanical and horticultural, offering a feast for the senses. It's a celebration of design, detail, and community in a setting unlike any other. The Village gets busy that Saturday. The canyon does not.
The closing bookend is the Fall Festival. The 7th Annual CdM Fall Festival Meet & Greet gathers over 350 residents, businesses, and neighborhood friends to celebrate the fall season, at the beautiful Sherman Library & Gardens, where the autumn foliage will transport you to a magical country scene of countless pumpkins. Once the Fall Festival lands, weekend energy in the Village shifts back to peak. Between those two Saturdays, the canyon is at its quietest and coolest, the guided programming has resumed, and PCH is off its summer peak.
That's the window.
The guided programming worth booking
Irvine Ranch Conservancy runs a rotating docent calendar out of Buck Gully, all free with registration at letsgooutside.org. Three formats to know:
The evening hike is the one to prioritize in September. The Buck Gully Upper Loop Evening Hike explores the reserve during the beautiful early evening hours from 3 to 5:30 p.m. The stream is running, and the rich plant and animal life are enjoying the cool, shady canyon, making for an evening hike in a natural oasis amid the suburban surroundings.
The full-length loop is the one to book if you've only ever hiked to the second bridge and turned around. The Buck Gully Loop Hike begins from the OASIS Senior Center, hikes up through the almost three-mile length of the canyon, then along San Joaquin Hills Road for about a mile, stopping at Canyon Watch Park, where you take in the panoramic view of the reserve and the Pacific coastline before descending back into the canyon along the Bobcat Trail. This hike is 6 miles, duration 3.5 hours with high-moderate difficulty. Meet-up is the auxiliary lot at 5th and Marguerite.
The volunteer option is the Fourth Friday Habitat Restoration. The Fourth Friday Habitat Restoration in Buck Gully offers an opportunity to help improve wildlife habitats by planting native species and removing non-native plants. It's the closest thing the neighborhood has to a standing volunteer date, and it's the one your neighbors on the ridge above the canyon should know about since a concerted effort is being taken to remove the non-native and fire-prone plants and trees, with volunteers, under the direction of the Conservancy, working on the City-owned property within the hazard reduction zone.
Where locals land afterward
The Poppy trailhead spills you back onto East Coast Highway within a five-minute walk. A short list of what's actually open and worth the stop, all on PCH:
| Stop | Address | Best for |
|---|---|---|
| Bamboo Bistro | 2600 E. Coast Hwy | Post-hike lunch, recent expansion |
| Bandera | 3201 E. Coast Hwy | Rotisserie counter seat, walk-in |
| Foretti's CDM | 2929 E. Coast Hwy | Wood-fired pizza, later start |
| SideDoor at Five Crowns | 3801 E. Coast Hwy | Small plates, fireplaces |
| CDM Restaurant | 2325 E. Coast Hwy | Speakeasy after dinner |
A few reasons these earn a spot over the obvious picks. Bandera is a Hillstone room where you'll find a neighborhood restaurant where you can enjoy the exciting theater of a kitchen in the round, with rotisserie chickens slow-roasted over a hardwood fire in a custom stone oven, which is a hard walk-in on a Saturday but a clean 2 p.m. bar seat mid-week after a canyon loop.
Foretti's runs a Naples-certified oven under new ownership. The restaurant specializes in authentic Associazione Verace Pizza Napoletana-certified wood-fired pizzas baked in a 900 degree oven with the same techniques and ingredients used in Naples, Italy, with house-made pastas and Orange County wine on the list.
SideDoor is the quieter half of Five Crowns and does what you actually want after four miles in the sun. Refurbished, restyled and re-opened as Corona del Mar's first and only English-style gastropub, SideDoor's focus is on seasonal small plates portioned for sharing, cheese and charcuterie prepared by a chef on duty at the new charcuterie station.
CDM Restaurant is the one to know about for later in the evening because Under CDM is a speakeasy experience taking place right below, with no password or reservations required, which is a useful piece of information when a Friday evening hike wraps up at eight and the group wants one more stop.
One last read before you go
A practical note the AllTrails reviews don't emphasize: this trail is periodically closed due to weather conditions, and it can get very narrow and muddy. After the first meaningful rain of the fall, the sandy sections and creek crossings wash out and take a week or two to firm back up. If you're heading in on a weekday morning after rain, expect mud, not closure.
The pattern to hold onto: the reserve rewards residents who treat it like a working landscape rather than a scenic backdrop. Read the closures, respect the one-way rule, book one docent-led hike per season, land at Bandera or SideDoor afterward, and the eight weeks between Petals & Pistons and the Fall Festival become the most useful stretch of the CdM calendar you're currently underusing.
If you're weighing a move within Corona del Mar, or thinking about how your current block sits relative to the trail system and the Sherman calendar, I'm happy to walk the canyon and the neighborhood with you. Reach out through Ashley Marie to schedule a consultation.
