Foaming water spills 30 feet over Crawfish Creek, sending a mist across the spruce. View from above is possible near the trail exit, or you can descend a steep path to the base for a closer look. The drop results from hydrologic erosion, with geothermal warmth shaping the local habitat.
Late spring through early fall, when the weather is warmer and roads are open. In the early morning, mist over Crawfish Creek and low light create a soft glow for photography; evenings can also work as the falls sit in shade. Avoid midday sun for the best results. The South Entrance road closes in winter, so plan accordingly. The small parking area fills during peak seasons, so arrive early.

Parking is limited and fills quickly in peak season; plan to arrive early or use the overflow areas and be prepared for a short walk from the lot.
Yes. The close-up view reveals spray and heat-enhanced habitat; the steep descent is part of the experience, but footing can be slick, so take your time.
Dogs aren’t permitted on the trail to the base; they may be allowed in developed areas only—plan to keep pets secured away from the trail.
Do not touch or swim. Geothermal activity can heat water unexpectedly and cause burns; stick to established overlooks and be mindful of hot eddies.
Early mornings during golden hour give soft light and enhanced mist; avoid harsh midday glare when possible.
