That’s where Mr. Rent a Car comes in. Renting a car directly from Ontario Airport through Mr. Rent a Car gives you the flexibility and freedom to travel like a local. Whether you’re into nature, history, shopping, or food, you’ll find a perfect day trip waiting just a short drive away.

Here are 7 top day trips you can enjoy with your Mr. Rent a Car rental.

1. Big Bear Lake – For Mountain Lovers

Distance: Approx. 1.5 hours (80 miles)
Why Go: Perfect for year-round outdoor fun

Hop into your rental car from Mr. Rent a Car and head north into the San Bernardino Mountains. Big Bear Lake is a peaceful escape with fresh mountain air, scenic hiking trails, water activities, and even snow in the winter. It’s a local favorite for skiing, snowboarding, and cozy cafes.

Don’t forget to drive around the lake for some picture-perfect views. Parking is easy with your own vehicle, and you’ll love the flexibility to explore hidden trails and spots off the beaten path.

2. Joshua Tree National Park – Desert Vibes and Natural Beauty

Distance: Approx. 2 hours (100 miles)
Why Go: Surreal desert landscapes and unique rock formations

A rental car from Mr. Rent a Car makes it easy to plan an early start and head east into the high desert. Joshua Tree National Park is unlike any place you’ve ever seen. With its iconic twisted trees, boulders, and stargazing spots, it’s a day trip you won’t forget.

Be sure to bring plenty of water and snacks, and enjoy the drive through wide-open desert highways. Pro tip: Stop by Joshua Tree Village for a bite and some local art galleries before heading back.

3. Laguna Beach – A Relaxing Coastal Escape

Distance: Approx. 1.5 hours (60 miles)
Why Go: Scenic coastline, tide pools, and art galleries

Laguna Beach is an easy drive from Ontario Airport with your Mr. Rent a Car vehicle. This artsy beach town is known for its beautiful cliffs, walkable downtown, and relaxing beaches. It’s perfect for a lazy day in the sun or an afternoon browsing local shops and galleries.

Parking near the beach is much easier with a smaller rental car, so keep that in mind when choosing your vehicle!

4. Temecula – Wine Tasting and Hot Air Balloons

Distance: Approx. 1 hour (55 miles)
Why Go: Vineyards, old-town charm, and scenic rides

Looking for something a little more sophisticated? Head south to Temecula Valley, SoCal’s wine country. With your car from Mr. Rent a Car, you can tour vineyards at your own pace, enjoy wine tastings, and grab lunch in the charming Old Town Temecula.

While public transportation options here are limited, having your own vehicle makes visiting multiple wineries in a single day a breeze.

5. Palm Springs – Retro Glamour and Poolside Vibes

Distance: Approx. 1 hour 20 minutes (75 miles)
Why Go: Mid-century design, shopping, and sunshine

With wide, open roads and sunny weather year-round, Palm Springs is an ideal destination for a day trip. Rent a stylish car from Mr. Rent a Car and head east to this desert oasis. Lounge by a hotel pool, shop downtown, or take a ride on the Palm Springs Aerial Tramway for mountain views.

Driving around Palm Springs is half the fun—don’t be surprised if you spot a celebrity or two while cruising through town.

6. Los Angeles – The Classic SoCal Experience

Distance: Approx. 1 hour (35–50 miles, depending on your destination)
Why Go: Hollywood, museums, food, and more

Want to see what all the buzz is about? Hop in your Mr. Rent a Car vehicle and make the trip to LA. You can hit hotspots like Griffith Observatory, Hollywood Boulevard, Santa Monica Pier, and The Getty Center—all in one day if you plan it right.

Having your own rental car gives you more control over your time, plus it’s far more convenient than relying on LA’s slow public transit.

7. Lake Arrowhead – A Quieter Mountain Alternative

Distance: Approx. 1 hour (50 miles)
Why Go: Peaceful lakeside town with alpine charm

If Big Bear sounds a bit too busy, Lake Arrowhead is a quieter, more romantic option. The drive up the mountains in your Mr. Rent a Car rental is scenic and fun, with winding roads and beautiful views.

Once there, you can stroll through Lake Arrowhead Village, sip coffee by the water, or take a boat tour. It’s a perfect spot for couples or anyone looking to unwind.
