Camping
Tennison Bay Campground: Beginning in 2026, all shower buildings in the Tennison Bay Campground will be renovated to upgrade the buildings utilities. Construction of the three buildings nearest campsites 226E, 312E and 425E is estimated to take place from April to November 2026.
To avoid shutting down this campground for the entire 2026 season, campers should expect some construction noise on weekdays between 8 a.m. and 6 p.m. Campsites 222, 226, 333, 360, 425, 426 and 427 will be closed and used as staging areas for these renovations.
The two shower buildings nearest campsites 322E and 476 are open for the 2026 season and will be renovated in spring 2027.
Eagle Tower
Eagle Tower is open seasonally from approx. May 1 to Oct. 31. Weather permitting, the open season may extend into late fall or begin earlier, however, visitors should expect the tower to be closed in the middle of winter. For more information, please see the Eagle Tower webpage.
Mountain Bike Trails
Peninsula State Park is working to improve the mountain bike trail system and other park trails as identified in the property’s approved master plan. For more information and maps of project work, please see the Trail Projects webpage.
