Map 3 covers the Boundary Waters south of the Echo Trail, plus a small part of the area north of the Echo Trail. The two most popular Boundary Waters entries on Map 3 south of the Echo Trail are in the west at Trout Lake (EP1) and in the east at Crab Lake (EP4). Motorboats are prohibited on all lakes within the BWCAW on Map 3 except Trout Lake, which allows motors up to 25 horsepower with a proper permit.
The majority of visitors to the BWCAW south of the Echo Trail enter from Trout Lake or Crab Lake. Greater solitude can generally be found by starting at one of the northern entry points or by paddling deep into the wilderness from Trout and Crab Lakes. See Maps 1, 2, and 4 for more information about areas north of the Echo Trail.
