I did a search on here but not much comes up on Grand Lake in OK. boat launches or marinas. What I have so far looks like this;
Dripping Springs Marina - Does not look to have a ramp
Indian Hills Marina - Looks to have a decent ramp and may have transient slips
Scissor Tail Marina - Looks like it has a boat ramp but no answer so not sure on transient slips

Most everything else that calls itself a marina is just boat sales or no ramp. The public ramps don't look like a good option but its hard to tell from google. I found a VRBO with plenty of room for trailer storage. If any one has more info on ramps, marinas with transient slips I would appreciate it. Our boat is a 30' so it's not that big we are likely going to stay a week or so.

Thanks in advance

Couple years back I had made reservations at https://shangrilaok.com/marina/

Looks to be a full service marina and they had trailer parking..

I didn't go in the end since they canceled the GLOC shootout so I've never been there first hand

What end of the lake are you hitting?

South end-
Clearwater Bay. good ramp. Plenty of trailer parking. Great guys.
Ugly's Good ramp. Public ??? Unless you know somebody.

Shangri-la- Decent ramp. Trailer parking. VERY nice complex now if you still need somewhere to stay.

In Grove- Wolf Creek. Excellent ramp. BUT its shallow coming south past Sailboat bridge --Beware.

We are staying in Disney at least that's the plan, Clearwater Bay is close thank you. It looks like there are plenty of places to get a burger/beer on the water and we have been told there are 3 places to hang/cove out 1 is party coveish (thats a no go for me) 2 is a little older crowd and 3 is family, kids, cruisers etc. When the guy was talking about the 3 spots I couldn't help but think of goldilocks and the 3 bears......

Appreciate the help.

Hammerhead Marina has 2 ramps. The south ramp is the better ramp. I used to put my 39 GTS in there with no problems. I think it’s a $10 honor system or something. They also have slips by the fuel dock.

As Quinlan mentioned, Clearwater on the south end is good and also Cedar Port by the dam. Park ramp at the spillways is on the main lake East of Disney but sometimes busy with the fishing guys.
Bubba mentioned Hammerhead/Willow Park in Ketchum which is also good.
Have pulled a Formula 41PC at both Clearwater and Willow Park with no issues.
Enjoy your time on GLOC!
