    A bounded National Digital Trails query returned connected USFS-originated, distance-bearing features for Parker Lake and Heart Lake, plus an approximately two-mile named Convict Lake Loop shore-trail component whose endpoints do not close. Fourteen selected public-domain features are retained in a versioned snapshot.

    The Mono Basin day-hike guide maps Parker Lake, Yost and Fern Lakes, and Lundy Canyon. Parker Lake is 1.8 miles one way. The Yost/Fern route splits 1.5 miles from its trailhead; Fern Lake is another 0.7 mile and Yost Lake another 2.3 miles. Lundy Canyon reaches 20 Lakes Basin in 5.4 miles one way; its bottom two-thirds are easier and its upper third climbs steep switchbacks. The guide publishes road and parking directions for each trailhead.

Before you go

These open questions need confirmation; Wayproof does not fill them with guesses.

Which candidate trailheads, roads, restrooms, and seasonal services will be open for the planned trip?

Access and developed facilities are seasonal and condition-dependent; recheck current Forest Service alerts and local trailhead status shortly before departure.
