The best time to go to Idaho Springs is generally from late spring to early autumn, specifically from May to October, when the weather is most favourable for outdoor activities.During these months, the temperatures are pleasant, typically ranging from 15°C to 25°C, making it ideal for exploring the surrounding mountains, hiking, and enjoying the town's historical sites. The clear skies and comfortable conditions are great for scenic drives like the Mount Blue Sky Scenic Byway, which is usually fully accessible during this period.For those interested in historical attractions and outdoor adventures, the summer months (June to August) are particularly good. You'll find all the local shops, restaurants, and the Argo Gold Mill and Tunnel open and fully operational. This is also the peak season for white-water rafting on Clear Creek.If you prefer cooler weather, fewer crowds, and the beauty of autumn foliage, September and October are excellent choices.
