A sandy beach for all to enjoy! Colorado State Park swim beaches do not have lifeguards on duty. Swim at your own risk. Children must be supervised by adults at all times. Swimming is permitted in the swim area only.
Water Safety
Colorado Water is Cold Water
Colorado waters are classified as "cold water" (anything under 70 degrees) for most of the year. Swimming in cold water risks cold water shock, which can lead to drowning even for strong, experienced swimmers.
Life Jackets Save Lives
The majority of swimming, paddleboarding and kayaking fatalities occur when people are not wearing a life jacket. By keeping you above water, life jackets can be a last line of defense that prevents a bad situation from getting far worse. Colorado law requires that all water vessels have appropriately sized life jackets readily accessible for every person on board.
Boating and Fishing
Boating
Power boating, sailing, jet skiing and canoeing are popular activities at Sweitzer Lake. Visitors also enjoy water skiing, swimming and scuba diving. Boaters are subject to Colorado boating statutes and regulation.
