Oregon Caves National Monument and Preserve is open year-round, although snow sometimes blocks the road to the park, and the visitor center is open when the cave is open for tours.
Cave tours are usually offered from mid-April to early November, but the schedule depends in spring and fall on weather conditions.
The Illinois Valley Visitor Center in Cave Junction, managed by the IVCDO under an NPS contract, also has information about the cave.

Cave-tour tickets are available online through the Recreation.gov website, and a limited number of tour tickets may sometimes be had first-come, first-served.
Tours vary in length and duration.
The basic ranger-guided "discovery cave tour", 90 minutes long, requires negotiating more than 500 steep and uneven stairs and passageways with as little as 45 inches (110 cm) between floor and ceiling.
Not recommended by the NPS for anyone with heart, lung, or mobility problems, the tour involves a total climb of 230 feet (70 m).
Children under 42 inches (110 cm) tall or who are unable to climb a set of test stairs on their own are not allowed on the full cave tour.
The NPS offers a limited number of off-trail "introduction to caving" tours by reservation only.

Since the cave is only 44 °F (7 °C) inside regardless of the outdoor temperature, the NPS recommends warm clothing for its tours.
Good walking shoes are needed to negotiate slippery and uneven surfaces.
Not allowed on the tours are flashlights, backpacks, large purses, tripods, or pets.
To protect bats from white nose syndrome, visitors must not take any clothing or equipment into Oregon Caves that have previously entered any other cave or mine.

Lodging is available in the monument at the Chateau, which has 23 rooms to rent.
Several hiking trails wind through the monument and adjacent forest lands.
Big Tree Trail, 3.3 miles (5.3 km) long, gains 1,100 feet (340 m) in elevation between the visitor center and Big Tree.
No Name Trail, 1.3 miles (2.1 km) long, begins behind the visitor center, follows Cave Creek, crosses it, and then climbs steeply to the west side of the monument.
Two short side trails lead from the main trail to waterfalls along No Name Creek.
Cliff Nature Trail, passing over marble outcrops and through fir forests, winds for about 1 mile (1.6 km) from near the cave entrance past the cave exit to Big Tree Trail.
Old Growth Trail, 0.8 miles (1.3 km) long, links the Chateau and visitor center to the main parking lot.
Other named trails entering the park include Cave Creek, Mt. Elijah, and Limestone.
In 2012, the Oregon Caves Historic District was expanded to include several segments of the trail system.

Hotels, bed and breakfasts, motels, and resorts in the vicinity offer a variety of accommodations.
Although no camping is allowed in the monument, the NPS maintains the Cave Creek Campground within the preserve.
Additionally, the USFS maintains a campground nearby, and there are private campgrounds and recreational vehicle parks in the vicinity.
The Chateau, generally open from early May to late October, has a restaurant, coffee shop, and delicatessen, and Cave Junction has several restaurants.
The monument grounds include several picnic tables.
