About Bartoo Island Boat-in Campground
Overview
Surrounded by clear waters of Priest Lake, the 25 sites on Bartoo Island provide the ideal getaway for people looking for a rugged, but highly rewarding, camping experience on the peaceful shores of Priest Lake. There are 24 single sites on the island as well as one group site known as Sunrise Group Site. This group site has been renumbered from site #001 to site #23 for groups of 10-30 individuals. All sites are only reachable by boat.
Recreation
Visitors enjoy all types of boating from kayaking to canoeing to power boating up the 3.5-mile thoroughfare, which leads to the Upper Priest Lake Scenic Area. The upper lake cannot be access by car, so water is an excellent navigation option.
Fantastic birding and wildlife viewing is available, as well as Huckleberry picking from mid-july to early fall, when the sweet berries can be found in abundance throughout the forests of Northern Idaho.
Swimming is a popular summer pastime and with beach access not far from the campground, visitors won't have any problem cooling off during warmer months.
Anglers will be excited to know that the waters of Priest Lake are home to record-breaking Mackinaw trout as well as Dolly Varden, Cutthroat and Kokanee.

Natural Features
Priest Lake spans 25,000-acres of incredible beauty, fed primarily by the waters of the Priest River. Named after the historical presence of Jesuit priests who settled in the lake area in the mid 19th century, Priest Lake is today a major tourist attraction, drawing water sports enthusiasts, photographers and birders alike.
The group campground is located on the east side of Bartoo Island at an elevation of 2,400 feet. Bartoo, spanning 219 acres, is one of nine islands on Priest Lake.
Summers at the lake are typically sunny and warm and wildlife in the area includes bears, deer and moose.

FAQ
How do I get a reservation at Bartoo Island Boat-in Campground?
Campsite Sniper's current snapshot shows none of the 1,100 tracked site-nights open for online reservation at Bartoo Island Boat-in Campground. That can mean dates are reserved, closed, not yet released, or offered first-come, first-served rather than online. Pick a site on the map to see its calendar, or set a free Campsite Sniper alert. You complete the reservation yourself on Recreation.gov.
Does Campsite Sniper book this campground for me?
No. Campsite Sniper sends alerts and direct Recreation.gov links. It never books, pays for, holds, hoards, or resells reservations.
How current is this availability data?
Campsite Sniper re-checks public Recreation.gov availability for this facility every hour and republishes whenever anything changes. This facility's data last changed at Sep 18, 2026 16:19 UTC; an older timestamp means nothing has changed since that time, not that checking stopped. Always confirm final availability on Recreation.gov when you book.
