Camping is a quintessential Montana experience - but these days, it's usually anything but spontaneous. With the best campgrounds in Montana accepting reservations nearly a year in advance, sometimes your favorite spots get snatched up before you can even plan your vacation dates.

Luckily, there are some campgrounds in the Last Best Place where reservations are not required. While that doesn't necessarily mean you'll get a spot (they are first-come, first-served, after all), if you time your trip right, your odds will be good. These are a few places that will take your tents and trailers, with no reservation required.

1. Holland Lake Campground, Condon

Located on the shores of Holland Lake in the Swan Valley, the Holland Lake Campground features 40 clean campsites, a day-use area, and a group site available for tent and RV camping. Some spots are solely available on a first-come, first-served basis.

Let's visit Holland Lake Campground for a little camping in MT in this virtual tour of the campsites you'll find in Swan Valley:

2. Cut Bank Campground, Glacier National Park

You'll find the Cut Bank Campground on the east side of Glacier National Park, and this small, peaceful place is nice and quiet. This is a primitive camping experience, meaning you should bring your own water and leave your RV at home. This is one of the most pristine no-reservation campgrounds in Montana.

3. Missouri Headwaters State Park, Three Forks

Want to camp where Lewis and Clark once stayed in 1805? Missouri Headwaters State Park is located just 3 miles from I-90, and while reservations are accepted, they also welcome last-minute arrivals based on availability.

4. Sundance Campground, Columbia Falls

When your campgrounds of choice at Glacier National Park are full, you could very well have some luck here. Sundance Campground has most of the comforts of home, from showers, laundry service, and bathrooms to very friendly owners. Sundance Campground is right beside Highway 2 at Mile Post 147 in Columbia Falls, MT.

5. Rainbow Point Campground, West Yellowstone

Rainbow Point Campground is definitely a popular place during the summer, so if you don't make a reservation, you should come mid-week if you'd like to secure a spot. Located on the banks of scenic Hebgen Lake, there are several single-family campsites, many of which have electric hookups. There are also picnic tables and campfire rings.

Rainbow Point Campground in West Yellowstone is a beautiful campground to enjoy some camping in Montana. View some footage of this lovely area in this review from the Gimpy Camper before you head out to enjoy your camping trip:

6. Spire Rock Campground, Gallatin Canyon

The 20 sites at Spire Rock Campground in the beautiful Gallatin Canyon can be reserved, but last-minute arrivals are always welcome. While the campground doesn't have drinking water, it does have handicapped-accessible toilets, picnic tables, firewood for sale, fire rings, trash pickup service, and fishing access.

7. Kintla Lake Campground, Glacier National Park

Kintla Lake Campground is Glacier National Park's most remote front country and car camping campground, located in the northwest section of the park known as the North Fork. Due to its remote location, it's rarely filled, offering campers a true sense of isolation. There are 13 campsites that sit right on the shores of the beautiful lake.

8. Hay Canyon Campground, Lewis & Clark National Forest

Fall asleep to the sounds of the South Fork Judith River, which will be mere feet from your tent at the Hay Canyon Campground. The 6 rustic campsites here are first-come, first-served, and there is no fee. Restrooms are provided, but you'll have to supply drinking water and everything else you need.

9. Whitefish Lake State Park

Located on the outskirts of Whitefish, this state park camping has 25 campsites that offer a variety of tent-only and RV camping opportunities, plus a new hike-bike campsite convenient for cyclists traveling the nearby Great Divide route. As with all Montana state parks, reservations are accepted, but they're not required, and last-minute campers have been known to score some great spots.
