Summer is open and fully operational but can be hot, humid, and buggy, and thunderstorms are common.

The Graham Cave viewing area lets visitors see the sandstone shelter that made the park a National Historic Landmark. Interpretive signs explain the Dalton culture evidence uncovered during excavations and the cave's place in North American archaeology. A short, mostly level path from the parking area keeps the site accessible to most visitors.
- Graham Cave Glades Trail EasyRV parking available
Graham Cave Glades Trail is a short loop hike through oak-hickory forest and sandstone glades above the cave. Hikers pass rocky outcrops and seasonal wildflowers with views of the surrounding woodland. The trail is family-friendly and suitable for a quick leg-stretch from the campground.
- Loutre River Trail EasyRV parking available
The Loutre River Trail follows the wooded corridor along the Loutre River at the edge of the park. Expect shaded walking, birdwatching, and occasional river views through the bottomland forest. It's a good choice for a cooler hike on hot summer days.
- Fishing on the Loutre RiverRV parking available
Anglers can fish the Loutre River inside the park for catfish, bass, and sunfish. A boat ramp provides access for canoes, kayaks, and small johnboats. A Missouri fishing license is required for anyone aged 16 or older.
- Picnicking and Day UseRV parking available
Graham Cave State Park offers picnic areas with tables and shelters shaded by mature hardwoods. Several shelters can be reserved in advance while others are first-come, first-served. Shaded parking pullouts make it easy for RVers to stop for a midday break off I-70.

The park's mix of forest, glade, and riverine habitat supports white-tailed deer, wild turkey, and a wide range of songbirds and woodpeckers. Early morning walks along the trails are best for spotting wildlife. Binoculars and a field guide add a lot to a quiet shoulder-season visit.
