Big Water Marina & Campground: Boat Launch, Slips, and Overnight Camping on Lake Murray

What Big Water Marina & Campground Offers

Big Water Marina & Campground sits on Lake Murray near Chapin, South Carolina, and combines boat access with overnight camping in one location. The facility operates a full-service marina with covered and open boat slips, a public boat launch, fuel dock, and dry storage. On the land side, the campground has RV sites with hookups and tent camping areas, making it a base for multi-day lake trips or weekend getaways centered on water recreation.

The marina serves both day-use visitors launching boats and overnight guests who want to moor their vessel and stay nearby. Lake Murray itself is a 50,000-acre reservoir created by a dam on the Congaree River, popular for fishing, skiing, and cruising. Big Water's location on the lake's western side puts it within reasonable distance of Columbia and the Midlands region.

Boat Slips and Marina Services

Big Water rents covered slips, which protect your boat from sun and weather, and open slips, which cost less but leave the boat exposed. Slip sizes vary, so the marina can accommodate smaller fishing boats, larger cruisers, and pontoons. Covered slips are typically reserved well in advance during peak season (spring through fall), while open slips may have more availability. Monthly and seasonal rental rates differ; contact the marina directly for current pricing, as rates change by season and slip size.

The fuel dock sells gasoline and diesel, allowing you to refuel before heading out or when you return. Dry storage is available for boats you want to keep on land rather than in the water—useful if you trailer your boat or need storage between trips. The public boat launch ramp accommodates trailers and charges a day-use fee; parking is available for vehicles and trailers.

Campground Sites and Amenities

The RV campground has sites with full hookups—water, electric, and sewer connections—so you can stay comfortably in your RV without needing to find a separate facility. Sites vary in size and some have pull-through layouts for easier parking. Tent camping areas are also available for those without an RV, typically at lower nightly rates. Both RV and tent sites have access to the campground's restroom facilities.

Amenities at the campground include restrooms with showers, picnic areas, and direct or nearby access to the boat launch. The proximity to the marina means you can park your RV, launch your boat, and spend the day on the water without moving your vehicle. Many visitors use Big Water as a home base for multi-day fishing trips or family lake vacations.

Fishing and Recreation on Lake Murray

Lake Murray is known for largemouth bass, catfish, and crappie, drawing anglers year-round. The 50,000-acre lake has numerous coves and points where fish congregate, and staying overnight at Big Water lets you fish early morning and evening hours without commuting. Many campers fish from the shore near their sites or launch boats for deeper-water fishing.

Beyond fishing, Lake Murray supports water skiing, wakeboarding, swimming, and cruising. The lake has multiple public access points, but staying at Big Water gives you a secure place to moor your boat and return to a campsite. Families often combine boating with camping, using the lake for daytime recreation and the campground for evening meals and overnight rest.

How to Reserve a Slip or Campsite

Reservations for boat slips and campsites are typically made by phone or in person at the marina office. During peak season (May through September), covered slips and RV sites with hookups fill quickly, so booking several weeks or months ahead is common. Off-season (October through April) usually has more availability and lower rates.

When you call or visit, have information ready about your boat size (length and beam) if you're renting a slip, or your RV length and hookup needs if you're camping. The marina staff can tell you what's available, explain the difference between covered and open slips, and discuss pricing. Day-use launch fees are typically paid at the time of launch and do not require advance reservation.

Location and Getting There

Big Water Marina & Campground is located near Chapin, South Carolina, on the western side of Lake Murray.

GPS coordinates and detailed directions are available on the marina's website or by calling ahead.

Seasonal Considerations and Weather

Lake Murray is open year-round, but the busiest season runs from May through September when water temperatures are warmest and school is out. Spring (March–April) and fall (October–November) offer pleasant weather, fewer crowds, and lower camping rates. Winter (December–February) is quieter but water temperatures drop, making swimming and water sports less appealing for most visitors.

Summer heat and afternoon thunderstorms are common in South Carolina, so covered boat slips are especially valuable during this season. Campground sites with shade from trees are more comfortable in summer heat. Fall and spring typically offer the best balance of comfortable weather, good fishing, and reasonable availability.

Frequently Asked Questions

Can I launch my boat for the day without camping overnight?

Yes. Big Water has a public boat launch ramp available for day-use visitors. You pay a launch fee and parking fee for your vehicle and trailer, then you can fish or cruise the lake and return to launch your boat back onto the trailer. No overnight stay or slip rental is required for day-use access.

What is the difference between a covered slip and an open slip?

A covered slip has a roof structure that protects your boat from sun, rain, and weather damage, extending the life of the boat's finish and interior. An open slip is a mooring space without overhead cover, leaving your boat exposed to the elements. Covered slips cost more but offer better protection; open slips are less expensive and work well for boats used frequently or for short-term storage.

Do I need to bring my own camping gear, or are sites equipped?

RV sites come with water, electric, and sewer hookups, so you bring your RV and plug in. Tent camping sites are bare ground or grass with no hookups; you bring your own tent and gear. The campground provides restroom facilities and showers for all guests, but you supply your own bedding, cooking equipment, and other personal items.

What fish are in Lake Murray, and when is the best time to fish?

Lake Murray has largemouth bass, catfish, crappie, and bluegill. Bass fishing is strong year-round but peaks in spring (March–May) and fall (September–November) when water temperatures are moderate. Early morning and late evening are typically the most productive times. Local fishing reports and the marina staff can tell you what's biting during your visit.

Is there a fuel dock, and what types of fuel are sold?

Yes, Big Water has a fuel dock that sells gasoline and diesel. You can refuel before heading out on the lake or when you return. Fuel prices vary; call the marina for current rates. The fuel dock is typically open during daylight hours during the boating season.
