About
Overview
Post Oak is located on the banks of Copan Lake in Oklahoma's Green Country. Camping, boating, picnicking, hunting and fishing are popular activities here.
Recreation
Copan Lake offers its visitors extensive opportunities for a memorable outdoor recreation experience. The lake is home to many species of game fish, including largemouth bass, white crappie, channel and flathead catfish, and various species of sunfish. Hikers and horseback riders enjoy exploring the area on 3 miles of trails that wind through the wooded and open meadows of the lake shore. 11,000 acres of land around the lake have been set aside for wildlife management. These lands are open for public hunting of deer, waterfowl, bobwhite quail, turkey, cottontail rabbit, and squirrel.

This campground offers 19 sites with electric hookups. Amenities include flush and pit toilets, showers, drinking water, and a dump station.
Natural Features
The 4,850-acre lake sits on the Little Caney River among a prairie landscape of grasslands and croplands.

Is POST OAK PARK fully booked?
A campground showing no availability is almost never full for good. People cancel — plans change, weather turns, someone books three weekends and keeps one — and the site goes straight back into the booking system, usually without warning and often at odd hours. The reason sold-out campgrounds feel impossible is not that sites never free up; it is that nobody is watching at the moment they do.
CampHawk watches POST OAK PARK in Copan, OK for you. We recheck it every 15 seconds, around the clock, and the moment a site opens we send a text, an email and a push notification — and on Recreation.gov we can put the site straight into your cart, so it is held while you get to your phone.
Searching is free and needs no account — the calendar above is live right now. Watching POST OAK PARK for cancellations is the paid part.
