[ Google Review ] What a majestic place! We spent 7 days in this wonderful national park and we enjoyed every single minute. Going to the sun road is amazing and very reminiscent of Switzerland. The campgrounds are full in August and make sure you reserve you camping spot several months before your trip. I saw multiple cars driving around looking for a camping spot with no luck. If you love hiking, Highline trail is beautiful for sight seeing and observing the wild animals. The hike can take 10-12 hrs depending on how fast you are and on the hike conditions. We did in August and some spots had snow on the ground due to recent snow storm. Also, you can park the car at the end of the trail and take the shuttle to Logan pass and start the hike there. Make sure you check the shuttle hours since they vary. In addition, keep in mind that going to the sun road is closed from September til early June. My favorite part of the park is the Many Glacier side and we stayed at the Swiss Lodge which is worth to stay at least one night if they have availability. There is another gorgeous hike from many lake to the glacier but you need to take the boat pass or wake up earlier and hike two lake before you get to real hike.
