Ten More Tips for a Perfect Lake Day

1. Arrive early: Popular lakes can get crowded fast, especially on weekends. Arriving early means better parking, prime picnic spots, and calmer water for paddling or swimming.

2. Bring shade: Not all lakes offer natural cover. A pop-up canopy, beach umbrella, or wide-brim hat can make a big difference in staying cool and avoiding sunburn.

3. Pack smart: Bring the essentials: sunscreen, bug spray, towels, a first aid kit, and plenty of water. Don’t forget a dry bag for electronics and a cooler with snacks or lunch.

4. Check conditions: Before heading out, check the weather, water quality reports, and fire bans if you’re grilling or camping. Colorado lakes can experience afternoon storms and sudden wind gusts.

5. Respect the rules: Follow posted signs and lake regulations – like no-wake zones, dog restrictions, or swim boundaries. It helps keep everyone safe and preserves the environment.

6. Layer up: Even in summer, mornings and evenings can be chilly at higher elevations. Bring a light jacket or hoodie so you’re comfortable from sunrise to sunset.

7. Don’t forget entertainment: Bring a Bluetooth speaker for tunes, a book, paddleball set, or a frisbee to keep the good vibes going during downtime.

8. Be water wise: If you’re boating or paddling, always wear a life jacket – even strong swimmers. Kids and pets should be monitored closely near the water.

9. Leave no trace: Pack out all trash, recyclables, and gear. Help keep Colorado’s lakes clean and beautiful for the next visitors.

10. Capture the moment: Bring your phone or camera (in a waterproof case!) to snap sunset shots, wildlife sightings, or group selfies. These are the summer memories you’ll want to keep.
