"Walk The Boardwalk!" Yellowstone National Park Things to Do Tip by johngayton

A couple of miles after Madison on the road to Old Faithful there is a short off-road "Nature Trail" which takes in The Fountain Paint Pots and several other geothermal features of the park.

This half-mile trail takes in examples of virtually every geothermal activity on the planet including geysers, the aforementioned mudpots, hot springs and the odd fumarole.

The trail itself is boarded, though can be very icy in winter, but gives you a welcome chance to stretch the legs especially on the way back towards the West Entrance. Note: Smoking not advised on the trail itself due to the sulpherous emmanations!

There will be more pics on travelog.

Directions: About 2 miles before (or after depending) Madison, on the Old Faithful road.
