Keystone Harbor of Oklahoma Marinas

RV Park

Overview

Overview

Positioned along the water, Keystone Harbor of Oklahoma Marinas in Mannford, Oklahoma places travelers right at the edge of one of the region's prominent aquatic recreation spots. This waterfront location speaks directly to those who travel with boats in tow or simply want water views just outside the RV door. Operating primarily as a marine-focused destination, it draws travelers looking to spend their days on the expansive surface of the local lake rather than staying isolated in an inland woodland campground.

Location & Surroundings

Situated in Creek County along State Highway 51, this destination sits in the rolling green transition lands of northeastern Oklahoma. The local climate brings warm summers and mild winters, typical of the region surrounding the Tulsa metropolitan area. Travelers arriving here navigate well-paved state highways that wind past scrub oak forests, rocky shorelines, and wide-open views of the Arkansas River basin watershed. The surrounding topography offers scenic driving routes across rolling hills.

Amenities & Park Features

Because the title clearly indicates a marina setting, visitors can anticipate a strong focus on boating infrastructure, boat slips, and water access points rather than sprawling resort-style facilities. Because exact site dimensions, hookup availability, and electrical configurations vary across waterfront properties, RVers should confirm hookup types and site pads directly with management before arrival. Essential inquiries should cover water pressures, sewage disposal access, and whether specific sites accommodate large slide-outs or heavy tow vehicles.

Nearby Attractions & Things to Do

Outdoor enthusiasts find endless recreation centered around Keystone Lake, offering miles of shoreline for fishing, boating, and waterskiing. A short drive east leads to Tulsa, Oklahoma, where visitors explore the Gathering Place park, the Philbrook Museum of Art, and the historic Route 66 architecture. Anglers frequently target the local waters for striped bass, largemouth bass, and catfish, while hikers utilize nearby wildlife management areas for regional bird watching and trail walking.

Who This Park Is Best For

This waterfront spot suits boating enthusiasts, anglers, and road-trippers wanting direct proximity to the water without staying deep within a standard state park. It works exceptionally well for travelers seeking a basecamp for watersports who also appreciate being within a reasonable driving distance of urban conveniences. Travelers prioritizing a quiet lake setting over dense urban RV resorts will find this Mannford location matches their travel style.

I'm in with a friend renting a slip. We mostly crappie fish, but the Marina offers a restaurant, social events and boat rentals for those who may not have fishing interests. Management is great. Have gotten to know all of them on a personal basis. They are interested in families having a good time. Keystone experienced high water levels for most of the summer. They have maintained the docks under difficult conditions, and The Harbors at Keystone is is in great shape.

From start to finish great experience. Called day of and got a boat rental. When we arrived, boat was clean and ready to rock. Every interaction with the employees was kind and friendly. They assisted in getting our cooler and stuff on the boat, and just in general were fantastic! Highly recommend!!!!

Can’t beat the view from my site. Marina staff is top notch. We get breakfast at the grill at least once a week with Christina and let me tell you, Danielle cooks it up right!

Sent an email almost 2 months ago. They have a waiting list. They didn't contact me or email me. Because i am the customer i am at fault for not stalking them over and over again to get in contact with me. At least put me on the list from when i contacted you, even forwarded the email... nothing but excuses. I am moving to the area. It is a small world... if they contact me with my business, i guess they will be on my waiting list. Again, another worthless experience because no one knows what customer service is..... always customer at fault or someone else... pitiful.
