Your Foothills Summer 2026: Events Worth Leaving the House For

The thing nobody tells you when you move to the foothills: the summer calendar is stacked. Free concerts most nights of the week, a minor-league ballpark you can walk into for the price of lunch, farmers markets in three towns, and a fireworks show you can hear from your backyard. We sell homes here because we love living here — so here's the insider list, grouped to scan fast. Bookmark it, then go.

The summer at a glance

Most of the good stuff runs June through August, but a few anchors start before Memorial Day. Here's the season on one line:

Schematic. Dates per LA County Fair, MiLB Quakes and city pages cited below.

Live music & festivals

Three cities run free summer concert series, and they don't overlap — so you could catch live music several nights a week without spending a dime.

• Ontario Summer Concert Series — runs roughly late May into August at Ontario Town Square and Celebration Park North, with food, games and prizes before the band. Free. City of Ontario special events.
• La Verne Concerts in the Park — Sunday evenings at Heritage Park (5001 Via De Mansion). Bring a blanket and a lawn chair; it's the most "small-town" of the bunch. City of La Verne.
• Victoria Gardens Summer Concerts — weekend evenings in the courtyards at Rancho Cucamonga's open-air town center, paired with free Summer Night Movies. Victoria Gardens events.

And the big one: the LA County Fair at the Pomona Fairplex runs May 7–31, 2026 ("Play Your Way"), Thursdays through Sundays plus Memorial Day. It's a spring fair, not summer — so don't sleep on it. lacountyfair.com.

Farmers markets

Saturday and Sunday mornings are for produce, coffee and people-watching. Two reliable picks:

• Claremont Farmers & Artisans Market — Sundays, 8 a.m.–1 p.m. on Harvard Avenue in the Claremont Village, rain or shine. Around 60 vendors, plus the walkable Village to wander afterward. claremontforum.org.
• Victoria Gardens market — a smaller Friday-morning market with local vendors and live music in Rancho Cucamonga. Easy to pair with breakfast. victoriagardensie.com.

Sports & the outdoors

The Rancho Cucamonga Quakes are the easiest fun in the valley. The 2026 season runs May 19 through Aug 30 at LoanMart Field (a.k.a. "The Epicenter," 8408 Rochester Ave). Cheap seats, fireworks nights, and a ballpark small enough that there isn't a bad view. Full Quakes schedule.

For getting outside without driving far:

• Cucamonga-Guasti Regional Park (Ontario) — 150 acres with two fishing lakes, a splash pad and shady picnic shelters. Day-use entry runs about $10–$15 per vehicle; bring a state fishing license if you're casting. San Bernardino County Parks.
• Mt. Baldy scenic chairlift — ride up to the Top of the Notch lodge at ~7,800 feet for cool air and big views; the trailheads up top range from easy strolls to serious climbs. Confirm summer operating days before you go. mtbaldyresort.com.

Family & July 4th

Two crowd-pleasers built for kids (and the kid-adjacent):

• Rancho Cucamonga Summer Movies in the Park — free outdoor films at dusk, Tuesdays at Chaffey Town Square (Victoria Gardens) and Fridays at Red Hill Community Park, roughly early June into late July. Games and crafts beforehand. cityofrc.us.
• Upland "Light Up the Night" Fireworks Spectacular — the area's marquee July 4th show at Cable Airport, with live music, a kids' zone, a Ferris wheel and a real fireworks finale. Tickets are required and sell only online in advance — grab them early. City of Upland 4th of July.

Where it all is

Our service area sits in a tidy row along the base of the San Gabriels. Here's a stylized map so you can see how close everything really is — these cities are 10–20 minutes apart, not a road trip.

Not to scale. The mountains run along the top; the cities string west-to-east below them.

This is the part of the job we like best: not just handing over keys, but telling you where to be on a warm Friday night. If you're weighing a move into the foothills — or you already live here and want to know what your home's worth in this market — we're a phone call away.
