After landing at Charleston International Airport, collect your rental car and allow roughly 25–35 minutes to reach the Historic District, depending on traffic. Check in, drop your bags, and head to the Charleston City Market for an easy first look at the city. Give yourself about an hour to browse the stalls, especially the handwoven sweetgrass baskets made by Gullah artisans. The market generally operates during daytime and into the early evening, but stall hours vary, so arriving before 5 p.m. gives you the best selection. Parking garages around the Historic District are easier than hunting for curb space; expect roughly $2–4 per hour.
Walk or take a short rideshare to Hank’s Seafood Restaurant in the French Quarter—about 10 minutes from the market on foot. This is a good first-night choice for classic Lowcountry seafood in a polished setting: plan on approximately $35–60 per person before drinks and gratuity. Dinner reservations are strongly recommended, particularly for a summer evening; if your flight runs late, call the restaurant rather than trying to squeeze in at the last minute.
After dinner, walk about 8–10 minutes to Waterfront Park. The park is free and especially pleasant after sunset, when the palms and harbor breezes take the edge off Charleston’s August heat. Spend around 45 minutes near the Pineapple Fountain, but avoid climbing on or entering the fountain area. From there, continue roughly 12 minutes south toward Rainbow Row for a brief architectural stroll along East Bay Street. The colorful eighteenth-century homes are best enjoyed from the sidewalk, and the area is quiet enough for an unhurried first-night wander. Keep water with you, wear comfortable shoes, and use a rideshare back to your hotel if the heat, humidity, or flight fatigue catches up.
Start early at The Battery, ideally around 8:00 AM, when the waterfront is cooler and the streets are quieter. Walk south along the promenade for broad views across the harbor, then turn through the residential lanes of South of Broad to admire the grand homes and detailed ironwork. Allow about an hour, and wear comfortable shoes—the best experience comes from wandering rather than rushing between landmarks.
Continue directly into White Point Garden, where live oaks shade historic cannons and monuments overlooking the water. Spend roughly 45 minutes here, taking the time to sit beneath the trees and enjoy the breeze. From the garden, Nathaniel Russell House is about a 10-minute walk through Harleston Village. Tours generally begin in the morning and last about an hour; reserve a timed admission in advance if possible, as summer tours can fill. Admission is typically around $15–20, and the house’s spiral staircase and restored neoclassical interiors are the highlights.
Walk north toward the French Quarter for lunch at Poogan’s Porch, housed in a historic townhouse on Queen Street. Expect classic Lowcountry and Southern dishes, with lunch usually costing about $25–45 per person before drinks and tip. A reservation is wise, particularly on a summer weekday, though arriving a little before the main noon rush may help. After lunch, take a rideshare or walk approximately 15 minutes to the International African American Museum near the eastern end of the peninsula. Plan about two hours here; its galleries thoughtfully trace African American history from West Africa and the transatlantic slave trade through Lowcountry communities and the wider American story. Timed tickets are recommended, and admission is generally around $20–25. The museum is air-conditioned, making it a welcome, meaningful pause during Charleston’s August heat; allow extra time afterward to reflect rather than packing in another major sight.
After breakfast in Charleston, leave around 8:00–9:00 AM for Myrtle Beach via US-17, allowing 2–2½ hours depending on traffic. Rather than checking in and backtracking, continue south to Murrells Inlet and park at Brookgreen Gardens; admission is typically around $25–30 for adults, with gardens, galleries, and seasonal events included depending on the date. Give yourself about three hours here—start with the sculpture gardens, then wander the shaded botanical paths and Lowcountry history areas. August is hot and humid, so bring water, sunscreen, and comfortable shoes; arrive before midday if you can, as the grounds are much more pleasant earlier.
After Brookgreen Gardens, drive roughly 10 minutes to Murrells Inlet MarshWalk, where a one-hour stroll along the waterfront offers broad marsh views and a relaxed introduction to the area. The boardwalk is especially attractive in the late afternoon, though sunset faces across the marsh rather than directly over the ocean. For dinner, settle in at Russell’s Seafood Grill, a casual local favorite near the MarshWalk; expect roughly $25–45 per person for seafood, and call ahead or join the waitlist during the busy summer dinner period. Afterward, continue to your Myrtle Beach hotel—about 15–25 minutes north, depending on where you are staying—and keep the evening easy rather than adding another attraction.
Start at Myrtle Beach State Park around 8:00 AM, before the sand heats up and the main beach crowds arrive. Walk the shoreline and the short coastal paths near the fishing pier, keeping an eye out for seabirds and the occasional sea turtle track in summer. The park generally opens at 6:00 AM; admission is usually about $8 for adults, with parking included once you enter. Allow about 1½ hours, then drive north to Ripley’s Aquarium of Myrtle Beach at Broadway at the Beach in roughly 15–20 minutes. Buy timed tickets online if possible—summer lines build quickly—and plan on about two hours for the shark tunnel, ray exhibits, and reef galleries. Admission is commonly around $40–50 per adult, depending on date and promotions.
Stay at Broadway at the Beach for lunch and a relaxed wander around the lake. This is the practical place to take a break from the heat: choose a shaded patio, browse the shops, and leave room for an ice cream or quick snack rather than committing to another large meal. Most shops open around 10:00 AM, and the complex is easy to explore on foot, though you may want to move the car to a different lot if the first one is busy. In the late afternoon, head downtown to the Myrtle Beach Boardwalk, about 10–15 minutes by car; parking garages and paid lots are more convenient than hunting for free street spaces. Walk the oceanfront promenade for about an hour and pick up a classic funnel cake, saltwater taffy, or lemonade as the temperature begins to ease.
For dinner, settle in at The Chemist, a former pharmacy-inspired restaurant and cocktail bar downtown. Its creative drinks and modern comfort-food menu make it a good change of pace from the casual beachfront stops; expect roughly $30–55 per person before drinks and tip. Reservations are sensible on a summer Friday, and arriving around 6:30 PM usually gives you a better chance of avoiding the busiest dinner rush. Keep the evening unhurried—after dinner, you can make a short return walk toward the ocean, but don’t count on easy parking later, when downtown traffic and the boardwalk crowds are at their peak.
Leave Myrtle Beach around 7:30–8:00 AM for Columbia, taking US-501 and I-20; the drive is usually 2½–3 hours. After checking in or dropping bags, park once in the Vista rather than moving the car repeatedly—street parking and paid garages are available near South Carolina State Museum. Plan about two hours inside, moving from South Carolina history and natural science to the art and technology galleries. Admission is typically around $15–20 for adults, and it is a particularly good hot-weather stop; check the museum’s current hours before leaving, as late-morning opening times can vary.
From the museum, walk roughly 10–15 minutes toward Riverfront Park, following the former canal and the Broad River. The riverside trail is an easy, mostly level stroll and takes about an hour; bring water, since the exposed sections feel hot in August. Afterward, drive or walk into the Main Street District for the Columbia Museum of Art, allowing about 1½ hours for its European, American, and contemporary collections. The museum is generally closed Mondays, so verify the August 15 schedule and admission details in advance; nearby garages make this the easiest point to leave the car for the rest of the evening.
Finish at Cola’s Restaurant, a short walk from the Columbia Museum of Art, for Southern-influenced American cooking in a lively downtown setting. Expect roughly $35–60 per person before drinks and tip, and reserve ahead for a Saturday dinner. Afterward, take an unhurried walk along Main Street or return to the hotel; Columbia’s summer evenings remain warm, so a brief stroll is more comfortable than planning another full attraction.
