During Summer and late Spring (from river height of approximately 1.5ft to 4ft), the highest classification of rapids are Class II. Our 10 Mile Challenge and Epic Overnight trips have multiple Class I and II rapids. All other trips have either Class I rapids or flat-water. In early Spring, river levels tend to be more unpredictable and much higher than in summer time. This means Class II rapids become Class III at high river levels and extreme caution should be exercised. Water temperature in Spring is also considerably cooler which should be taken in to consideration.
