3 nights starting Thursday after Labor Day. Was able to get the reservation 2 weeks ahead as it was released for use. Camping at this campground also gives you a time+ entry permit good for bear lake road. After 1 pm the first day and then anytime on following days. They have planted many new pine trees a few years ago to replace the ones destroyed years ago. Even then the shade in much of C loop is nonexistent. Thus a tarp is a good thing. Sites are reasonably well separated. In a few years as the new trees mature the privacy between sites will be good or very good. Restrooms were clean. Their time actuated lights makes the campground dark if no one is using the head. That is very good because star watching was excellent (near a new moon). Evening ranger program was held in the amphitheater each night. Hiking trail to sprague lake is about a mile with plenty of birds and other critters. We saw a weasel and a flock of turkeys. At sprague lake around 9 am the local moose goes wading to eat. And of course you are in the park, so you can drive to see elk, coyotes, pika, marmots and more. Great place. T-Mobile varied from 2 bars LTE or 2 bars 5G. Sufficient connectivity
