Diablo Lake

Difficulty	Distance	Steps	Elevation Gain
Moderate	7.6 Miles Round-trip	19,109 est.	400

Steps are estimated from the hike distance and a difficulty-based stride length.

Formula: distance in miles × 5,280 feet ÷ stride length

Stride length is adjusted because tougher trails usually shorten each step:

Difficulty	Stride length
Unknown	2.2 ft
Accessible	2.3 ft
Easy	2.6 ft
Moderate	2.1 ft
Difficult	2.0 ft
More Difficult	1.9 ft
Strenuous	1.8 ft

The result is rounded to the nearest whole step and shown as an estimate.

Notes

Diablo Lake is surrounded by snow-capped mountains and turns a gorgeous turquoise blue in the summer. This unique color is because of tiny rock pieces called glacial flour, which are carried into the lake by streams that feed glaciers. SR 20 typically closes about mid-November and reopens in mid-April.
