There’s something timeless about a good old-fashioned road trip. Windows down, playlist up, snacks within reach, and that undeniable excitement of discovering what’s around the next bend. At RADIUS, we’re always thinking beyond the bathroom sink. For us, summer means adventure, and adventure means keeping your oral care routine as fresh as your travel itinerary.
With that in mind, we’re rounding up some of the most scenic and soul-refreshing summer road trips across the U.S. for 2025. From coastal hideaways to desert drives, we’ve mapped out must-visit destinations that make the journey just as memorable as the destination. And of course, we’ll sprinkle in a few RADIUS essentials to help you keep those teeth and gums road-trip ready, wherever your travels take you.
1. Gulf Coast Cruising: Houston to South Padre Island, Texas
Distance: ~375 miles
Drive Time: ~6 hours
Best For: Beach lovers, family fun, warm weather
If South Padre Island isn’t on your 2025 travel list yet, it should be. This tropical treasure off the southern tip of Texas offers white sand beaches, warm Gulf waters, and plenty of sunshine. Kick things off in Houston, load up the car, and cruise south along I-69 for an easygoing, beach-bound adventure.
Pit Stop Suggestions:
-
Grab seafood in Corpus Christi
-
Take a dolphin-watching tour near Port Isabel
-
Explore the Laguna Madre Nature Trail for sunset views
Oral Care Tip: Long hours in the car and snacking on the go can dry out your mouth, especially in the Texas heat. Keep your hydration up and make time for a quick brushing break. We recommend packing your RADIUS Tour Travel Toothbrush, compact, eco-friendly, and designed to fold up neatly without the need for a bulky case. It’s perfect for beach bags, glove compartments, and carry-ons alike.
2. The Great California Coast: San Francisco to Big Sur
Distance: ~150 miles
Drive Time: ~3 hours (plus extra for scenic stops)
Best For: Breathtaking views, outdoor picnics, nature-inspired vibes
Few drives rival the Pacific Coast Highway. Starting in San Francisco, head south on Highway 1 and let the cliffs, coves, and coastal forests guide your journey. Along the way, stop to explore the charming town of Carmel-by-the-Sea, snap photos of Bixby Bridge, and breathe in the salty air from Pfeiffer Beach.
Pack This:
-
Picnic blanket
-
Binoculars for spotting sea lions
-
Your favorite audiobook for slow coastal stretches
Oral Care Tip: That sea air may be crisp, but car snacks (think sourdough and trail mix) can easily lead to food buildup between teeth. Keep your road trip feeling clean with the RADIUS Vegan Sponge Floss. It’s gentle, expandable, and made from plant-based ingredients, ideal for those moments when you want to freshen up before stepping out into a picturesque trailhead or coastal café.
3. Desert Vibes & Stargazing: Phoenix to Sedona to Flagstaff, Arizona
Distance: ~150 miles (one way)
Drive Time: ~2.5 hours
Best For: Hikers, spiritual seekers, and lovers of red rock scenery
Arizona’s high desert offers dramatic beauty, vibrant energy, and quiet moments to reflect, especially if you’re watching the stars over the red rocks of Sedona. Start in Phoenix, head north on I-17, and let your soul (and your camera roll) soak it all in.
Detour Ideas:
-
Stop by Montezuma Castle National Monument
-
Hike Cathedral Rock at golden hour
-
Visit Lowell Observatory in Flagstaff
Oral Care Tip: Changes in altitude and dry desert air can do a number on your hydration, and that includes your mouth. Don’t forget to brush regularly to prevent buildup, especially after outdoor meals. Traveling with kids? Make it fun and easy with RADIUS Super Duper Kids Toothpaste in Bubble Berry Mint. It’s organic, safe to swallow, and a big hit for road warriors under 10.
4. The Southern Comfort Loop: Nashville to Asheville, NC
Distance: ~300 miles
Drive Time: ~5 hours
Best For: Foodies, music lovers, mountain air fans
Start with honky-tonk vibes in Nashville and wind your way through the Appalachian foothills toward the artsy mountain town of Asheville. The route is dotted with charming towns, barbecue joints, and rolling green hills, so don’t rush it.
Don’t Miss:
-
A stop at the Lost Sea (an underground lake in Sweetwater, TN)
-
The scenic Blue Ridge Parkway
-
Asheville’s farmers markets and street music
Oral Care Tip: After a full day of southern eats and roadside treats, your mouth will thank you for sticking to your routine. The key? Simplicity. Our Big Brush with Replaceable Head is wide, soft-bristled, and designed to massage gums without over-scrubbing—a smart choice after a few pulled pork sandwiches.
5. New England Charm: Boston to Acadia National Park, Maine
Distance: ~280 miles
Drive Time: ~5 hours
Best For: Coastal walks, lobster rolls, historic towns
Craving cooler temps and salty sea breezes? This classic coastal route takes you from Boston’s cobblestone streets to Maine’s forest-meets-ocean majesty. Pass through quaint villages like Portsmouth and Camden before reaching the rugged beauty of Acadia.
Photo-Worthy Stops:
-

Oral Care Tip: Between all the seafood snacks and long drives, don’t forget your floss! Even in chillier climates, oral bacteria don’t take a vacation. Tuck our Vegan Sponge Floss into your travel kit—it doesn’t shred, glides easily, and expands to clean those hard-to-reach places after a lobster dinner or blueberry pie.
Tips for Keeping Your Oral Care Routine on Track While Traveling
No matter where your wheels take you this summer, it’s easy to let good habits slip in between pit stops and gas station snacks. But healthy gums and fresh breath don’t need to be sacrificed for spontaneity. Here’s how we stay grounded, even while on the move:
-
Pack a mini oral care pouch with your RADIUS favorites (travel toothbrush, toothpaste, and floss)
-
Brush at rest stops—you’ll feel refreshed for the next leg of the trip
-
Skip sugary breath mints and opt for water and natural, organic toothpaste
-
Stick to your rhythm—morning and night routines are just as important on vacation
