Tips & Recommendations
- 1Reserve campsites well in advance for July and August, especially at popular swimming destinations like Holland Lake, Seeley Lake, and Placid Lake State Park, which often fill up months ahead.
- 2Bring a wetsuit or shorty for children and those sensitive to cold water, as even in summer many Montana lakes remain quite chilly.
- 3Pack water shoes for rocky lake bottoms and to protect feet from sharp rocks and zebra mussel shells at some reservoirs.
- 4Always supervise children closely as most swimming areas lack lifeguards, and be aware that cold water can cause rapid hypothermia even for strong swimmers.
