Funnel Lake Access is reached via the Coyote Flat 4×4 trail, a moderately technical off-road route (3. 5/5 difficulty) located at approximately 10,300 feet elevation in Inyo National Forest near Bishop, California. The access involves a 1.

75-3 hour drive with river crossings, tight switchbacks, and rocky terrain requiring high-clearance 4WD vehicles; full-size trucks are manageable but trailers require careful navigation.

Dispersed camping is available around the lake's southern and eastern shores with no designated facilities, and campfires are permitted with a California campfire permit obtained from USDA Forest Service offices.
