Trolling is often productive along the east side, from Cisco Beach south. Jigging can also be good try around Bear Lake State Park and the area known as the Rock Pile. Fish range freely in this big lake, so a fish finder really helps. Downriggers are a big plus because they help get lures to the appropriate depth. Shore fishing is not particularly effective.
Fishing is usually good year-round, but is often particularly good in early spring and late fall.
Stuff Ya Gotta Do Make sure to leave enough money in your budget to get an official Bear Lake Raspberry shake. There are many stands that claim to be the original or the best, but they are all good.
