What Guests Are Saying
Big Larch Campground features clean, spacious sites, well-maintained facilities, and a great location near Seeley Lake, making it a wonderful spot for a long weekend or overnight stay. Guests appreciate the proximity to both the lake and the town, as well as the friendly atmosphere and ample room between campsites. However, some visitors reported issues with noise from fellow campers and generator use, particularly during busy holiday weekends.

Clean spacious campsite. It’s labeled as a “prime” location but none of the sites are actually close to the lake. Pit toilets well maintained with easy access to the town of Seeley Lake. Water spigot is nearby.

Great swimming area for all ages
Nice clean toilets
Large area between and around sites
Look out for old cement posts when backing into sites
Our site was long enough but very narrow

Big Larch has large beautiful sites and a wonderful boat launch and swimming beach. Very close to town without feeling like you are in town. I highly recommend Big Larch Campground.

I tried cancelling my reservation online the day before arrival and was unable to complete this on line. I them called the USFS park office but since it was the weekend I left a message telling them to cancel my reservation. The next "working day" I called and spoke to a park employee who transferred me to another person. They were not avaible so I left a message to have them call me. Not getting a call back I went to the campground and spoke with the host. He gave me an 800 number to call which indicated it was USACE. I told the person what had happened but since my reservation started the day before, she could not cancel the remaining days of my reservation or provide a refund. I explained to her that I wasn't concerned about the refund but wanted allow someone else to use the campsite for the rest of the week, noting this was 4 of July on Saturday. She said she could not cancel or allow someone else to use it. I did tell the host the spot would not be used, but he also said he had no control on cancelling the booking. He did make note of the site and hopefully he could leave a note at the campsite indicating it was open for the next few days
