California summers can be relentless. From triple-digit temps in the Central Valley to the sun-scorched streets of SoCal, it’s no surprise locals and travelers alike start dreaming of cooler places to wander. Fortunately, the Golden State is full of refreshing getaways where you can swap sweat for shade, swap asphalt for alpine air, and still get your fix of adventure.
This summer, skip the heat waves and head for breezy coasts, forested mountain towns, and scenic lakeside retreats. Whether you’re planning a long weekend road trip or a spontaneous day escape, this guide will take you to the coolest corners of California—literally.
Lake Escapes with Elevation
Lake Tahoe: Blue Waters, Breezy Pines
Tucked high in the Sierra Nevada, Lake Tahoe is a dream for those who want to cool off without sacrificing summer fun. With daytime temps hovering in the 70s and crisp nights perfect for campfires or hot cocoa, Tahoe is a refreshing change from the smoggy summer heat of the valley.
Spend your days paddleboarding across Emerald Bay, hiking the Rubicon Trail, or exploring the serene coves along the eastern shore. Boat rentals are widely available, and you can even hop aboard a sunset dinner cruise if you’re feeling fancy.
South Lake Tahoe is buzzing with beach bars, lakeside restaurants, and live music, while North Lake Tahoe offers a quieter, more relaxed atmosphere with cozy cabins and laid-back lakefront cafes. Wherever you land, the views are unbeatable.
For breakfast, don’t miss the Wildflower Café in Incline Village, and when hunger strikes post-hike, head to Gar Woods Grill & Pier for classic lakeside dining.
Mammoth Lakes: Mountain Air and Alpine Lakes
Farther south in the Eastern Sierra lies Mammoth Lakes, a high-elevation playground for outdoor lovers. At nearly 8,000 feet above sea level, Mammoth stays cool even in the dead of summer, offering a reprieve from the lowland heat.
The area is a hiker’s haven. Trails lead to sapphire-blue lakes, waterfalls, and panoramic mountain views. Convict Lake, Lake Mary, and Crystal Lake are local favorites, each perfect for picnics, paddleboarding, or simply soaking up the view.
The Mammoth Brewing Company offers a great place to unwind, and for a unique stay, check out Tamarack Lodge—a rustic-chic lakeside spot that feels like a step back in time.
Coastal Breezes and Fog-Kissed Mornings
Carmel-by-the-Sea & Monterey Peninsula
For a truly refreshing experience, head to the coast where fog often rolls in like nature’s air conditioning. Carmel-by-the-Sea and neighboring Monterey are some of the most charming and temperature-friendly towns in California.
Carmel’s European-style cottages, art galleries, and storybook streets offer a peaceful escape from the hustle. Wander through town, stroll the white sands of Carmel Beach, and enjoy the fresh salt air that rarely gets warmer than 70 degrees.
Nearby, the Monterey Bay Aquarium draws visitors from around the world, and Cannery Row is packed with shops, restaurants, and sea otter sightings. If you’re feeling adventurous, rent a kayak and paddle out into the bay for an up-close view of sea lions and playful harbor seals.
Dining here is an experience in itself. Try dinner at La Bicyclette in Carmel or indulge in the catch of the day at The Sardine Factory in Monterey.
Santa Cruz: Surf Town Chill
Just a little farther up the coast, Santa Cruz brings the beach-town vibe with a refreshing twist. Known for its foggy mornings and cool marine air, Santa Cruz rarely feels hot, even in the middle of July.
The Santa Cruz Beach Boardwalk is a nostalgic throwback to childhood summers, but the town also boasts beautiful hiking trails in Wilder Ranch State Park and natural wonders like the redwood groves in nearby Henry Cowell State Park.
Whether you’re watching surfers ride the waves at Steamer Lane or sipping a latte at Cat & Cloud Coffee, the vibe here is as cool as the breeze rolling in from the Pacific.
Forest Hideaways and Mountain Magic
Idyllwild: Pine Trees and Quiet Peaks
Nestled in the San Jacinto Mountains, Idyllwild feels worlds away from the hustle of Southern California. This artsy mountain town is surrounded by tall pines, rugged peaks, and fresh alpine air that’s typically 20–30 degrees cooler than nearby Palm Springs.
It’s a haven for hikers, climbers, and anyone in need of a peaceful reset. The Ernie Maxwell Scenic Trail offers a moderate hike with panoramic views, while the more ambitious can head up toward San Jacinto Peak for a full-day adventure.
Back in town, you’ll find local art galleries, small cafes, and even a jazz festival if you time your trip right. Be sure to visit Café Aroma for live music and hearty, homemade meals in a charming mountain setting.
Big Bear & Lake Arrowhead: Alpine Adventures Close to Home
If you’re looking for a quick escape from the Inland Empire or Los Angeles, Big Bear and Lake Arrowhead are just a couple hours up the road—and several degrees cooler.
Big Bear Lake offers hiking, fishing, kayaking, and even summer tubing if you’re looking for something a little different. The Alpine Pedal Path is great for a casual bike ride, while Castle Rock Trail rewards you with sweeping lake views.
Lake Arrowhead is slightly smaller and more upscale, but equally inviting. The Lake Arrowhead Village has quaint shops, summer concerts, and dining with views of the water. Both towns offer lakeside cabins and family-friendly activities without the high elevation fatigue.
Hidden Gems in the Hills
Julian: Apple Pies and Starry Skies
In San Diego County, Julian is best known for its legendary apple pies—but its cool mountain climate and quiet charm make it an underrated summer escape.
This former gold rush town sits around 4,200 feet in elevation and offers an ideal mix of small-town history and outdoor exploration. Visit the Volcan Mountain Wilderness Preserve for sweeping views of the desert below, or stroll the town’s Main Street for old-timey shops and bakeries.
When the sun sets, Julian becomes one of the best stargazing spots in Southern California, especially on moonless nights. It’s part of the official International Dark Sky Community, so don’t forget to look up.
Stop at Julian Pie Company for a slice (or three) of heaven before heading home.
Borrego Springs: Stargazing in the Desert
While it may sound counterintuitive to head to the desert to cool down, Borrego Springs offers something special—hot days, yes, but cool, quiet nights and world-class stargazing. As the only certified Dark Sky Community in California, it’s a magnet for astronomy lovers and night photographers.
Spend your day exploring the surreal metal sculptures of Galleta Meadows or hiking through Anza-Borrego Desert State Park’s palm oases. By dusk, temperatures drop significantly, making evening hikes and stargazing feel like another world entirely.
Stay at La Casa del Zorro for a touch of luxury with desert charm, or camp under the stars at one of the area’s quiet campgrounds.
