Yoho national park office is located in the small town of Field BC.
The campsite is just outside town on the road leading up to Takakkaw falls. The falls have a total height of 373 metres (with a main drop of 254 metres) making it the 2nd tallest waterfall in Canada. Takakkaw translates to "wonderful" in Cree.
Yoho is also home to the CP spiral tunnels carrying trains through the mountains to gain elevation through Kicking Horse pass - based on a Swiss design. Train nuts love this stuff - it was designated a national historic site in 1971.
