GuideWe loved our campsite up the mountain. The sites aren’t too close together. It’s quiet and peaceful. You feel like you’re in the woods not a parking lot like some campgrounds. The staff are super helpful. And the best part is it’s a mile from Glacier. We had the best stay!
Travelerliterally the best sleep i’ve had in months, lots of people around and everyone stuck to themselves
GuideThe Owner, Denise is the best. She texted us a long list of the surrounding Whitefish, MT businesses and downtown locations. She suggested the next door pizza place. 5 stars food. We will be coming back to this RV park
TravelerI'm a camp host at Finley Point Unit,Flathead Lake State Park. I can honestly say this is the most beautiful setting I've camped in. The campground is kept clean, the employees and the camp hosts ( including me) are friendly. I haven't seen one unhappy camper in 2 months. I highly recommend a stay at this park. One little tip. reserve in advance, the campground fills up fast.
GuideSites are dusty towards the end but the access to the river makes up for it.
LegendFairly peaceful here. I think it would be difficult to bring a trailer bigger than about 35 feet in here as the campground Road loop has some pretty tight corners around trees. Our spot was fairly easy to get into. Nice big area behind the trailer for setting up chairs and it had a picnic table with a camping. Wonderful 2 mile nature walk around the park down by the lake. We went down the road a few miles to the lodge and rented canoes for a couple hours. There are water spickets available for freshwater and several pit toilets. We paid $34 a night for nonMontana residents.
GuideNice, large dog park with plenty of room to run and play. Nice, spacious laundry room with plenty of machines. Nice, clean bathhouse with plenty of amenities.
GuideThis free campsite has absolutely gorgeous views and sits right along a beautiful river—definitely bring a kayak if you want to get out on the water! Keep in mind that there is a little ambient noise, as it is located close to the highway on one side and a railway track on the other. Overall, it is a stunning and convenient free location that is well worth a stop!
GuideThe main gate to the site was closed, so I decided to camp just uphill from the lake instead. It was $26 per night and well worth it. The site is very clean and quiet, equipped with potable water, picnic/dining tables, and clean restrooms. Great spot if you're looking for a peaceful setup near the water!
