Diamond Bar Center (1600 Grand Ave, Diamond Bar, CA 91765) is a city-owned event venue inside Summitridge Park, accessed off Grand Avenue. After dropping your group, the bus can stage in the main surface lot while your event runs. No advance bus parking reservation is published as required, but confirming current access with the venue directly at (909) 839-7070 before your event is always a smart move, since arrangements can shift by event.

Fairplex (1101 W McKinley Ave, Pomona, CA 91768) hosts the LA County Fair, NHRA events, concerts, and expos on its 487-acre grounds. For major events including the LA County Fair, which runs May 7 through May 31, 2026, the designated commercial vehicle and rideshare drop-off point is on White Avenue at Gate 17—that is the gate Fairplex directs buses and large vehicles to use for passenger unloading. After drop-off, buses are directed to Lot 9, the overflow and large-vehicle lot along the south perimeter near McKinley Avenue—standard car lots are not open to buses during major events.

For Fairplex Presents Oktoberfest 2026, parking is at Yellow Lot/Gate 17, while passenger drop-off uses Gate 1 at 1101 W. McKinley Ave; your bus gets the event-specific curb assignment instead of sending everyone through the general parking entrance.

For NHRA weekends and other high-demand dates, advance coordination is recommended. Confirm current lot assignments and gate access by calling Fairplex at (909) 623-3111 before your event, or check the Fairplex directions and parking page for the latest information.

Santa Anita Park (285 W Huntington Dr, Arcadia, CA 91007) is about 12 miles west of Diamond Bar via SR-57 North to I-210 West—roughly 20 to 30 minutes off-peak, longer on race days when the I-210 corridor backs up through Arcadia. For buses, drop-off is on Baldwin Avenue near the main gate entrance in the Gate 1 area at the Huntington Drive and Baldwin Avenue intersection—that is where Santa Anita directs large vehicles to unload passengers. After drop-off, buses are directed to park in the Lot 1 and overflow area along the north side of the property near Colorado Place.

Bus and oversized vehicle parking rates vary from standard admission and must be confirmed in advance. Call Santa Anita’s parking office at (626) 574-7223 before your visit, and check the Santa Anita directions and parking page for current access information. Major race days like the Santa Anita Derby in early April fill the surrounding streets quickly, so plan your arrival window with extra time built in.

Toyota Arena (4000 E Ontario Center Pkwy, Ontario, CA 91764) is about 7 miles from Diamond Bar via SR-60 East or SR-57 South to I-10 East—a straightforward run that turns into a slow crawl on event nights when Ontario Center Parkway backs up in every direction. Instead of sending your group in separate cars hunting for parking in the arena lots, your party bus handles the whole thing. Bus and oversized vehicle drop-off at Toyota Arena is on Convention Center Way, the road that loops the arena on the east and north sides, with the designated drop-off point at the north entrance near the main box office.

After dropping your group, buses stage in the Ontario Convention Center parking structure or in surface lots along Haven Avenue—not the standard arena surface lots. Confirm current bus parking arrangements with the arena at (909) 244-5500 or check the Toyota Arena plan-your-visit page before your event, since lot assignments can shift by show.

Fox Theater Pomona (301 S Garey Ave, Pomona, CA 91766) is about 4 miles from Diamond Bar via SR-60 West—close enough that the ride over IS part of the night. The theater sits right on Garey Avenue in downtown Pomona with no dedicated bus parking lot of its own. Buses drop passengers curbside on Garey Avenue in front of the theater for active loading and unloading, then need to relocate.

The closest practical staging for a party bus after drop-off is the Pomona Civic Center parking structure on Garey Avenue at Pearl Street, about 2 blocks north, or the Metrolink Pomona North Station surface lot on Pearl Street, about 3 blocks north—both are public lots with room for larger vehicles. Plan your post-drop staging before the night starts so the bus is ready and close when the show ends. For current downtown Pomona parking options, the Fox Theater Pomona website is the best starting point for event-specific guidance.

Frank G. Bonelli Regional Park (120 Via Verde, San Dimas, CA 91773) is about 5 miles north of Diamond Bar via SR-57 North—an easy run that makes it one of the most popular group-outing destinations for Diamond Bar residents. The park’s main entrance is on Via Verde, and the lanes are wide enough to handle full-size party buses without the tight-turn headaches you get at smaller venues. Buses enter through the main Via Verde entrance and drop passengers at the main day-use area parking lot near the swim beach entrance.

After drop-off, the bus parks in the designated large-vehicle and RV section of the same main lot—no need to relocate far from where your group is spending the day. A day-use entry fee applies; oversized vehicle rates are higher than standard car rates and should be confirmed before your visit by calling the park at (909) 599-8411 or checking the LA County Parks Bonelli Regional Park page for current fees and access information. The published county rate for a bus at Bonelli Regional Park is $38 per day, so the bus cost is clear before you arrive; the current county Bonelli Regional Park fee schedule carries the exact bus rate.

Stretch that to six months or more for the dates that fill fastest across the entire San Gabriel Valley market. Prom season across Diamond Bar, Walnut, Pomona, and Rowland Heights school districts runs April through May and is one of the single busiest stretches of the year—waiting until spring means higher prices and slim pickings.

The LA County Fair at Fairplex runs May 7 through May 31, 2026, and pulls demand across the whole eastern LA County area for a full month. Quinceañera season peaks in May through June and again in October through November. The cheapest windows to book a party bus in Diamond Bar are typically January outside of New Year’s weekend, early February, and September after Labor Day.
