Climbing and access information for this peak is on Page 52 of the book.
Trestle Peak is the northern anchor of a ridgeline that parallels the eastern shore of Lake Pend Oreille. A good Forest Service trail leads to near its summit from FS-275. The trail continues south past Peak 6357, Round Top Mountain, and Cougar Peak and ends at Porcupine Lake. I have only hiked the trail to Trestle Peak. USGS Trestle Peak
The Forest Service maintains a web page for this trail named the Bee Top/Round Top Trai. Please note that, on the USGS map, it is called the Alpine Trail.
