About Upper Sage Flat
Overview
Take the family to Upper Sage for a pleasant camping trip along the banks of Big Pine Creek. Here, visitors can experience the beauty of the creek that runs along the base of a narrow canyon. Visitors can swim or fish, in the creek that is stocked annually with trout, or head to a nearby lake for power boating.
Recreation
Rainbow, brown, brook and alpers trout swim in the stream, enticing anglers. Hikers are fans of the Big Pine Creek Trail, a 1.5-mile footpath that provides access to the John Muir Wilderness trails.
Facilities
Parking aprons are paved and most are 40 feet long. Amenities include flush toilets, drinking water, picnic tables and campfire rings.
Natural Features
The campground is sprawled out along Big Pine Creek beneath shady Jeffrey pines and cottonwoods, just 9 miles west of the town of Big Pine.
Inyo National Forest is home to many natural wonders, including Mt. Whitney, Mono Lake, Mammoth Lakes Basin, and the Ancient Bristlecone Pine Forest atop the White Mountains.
Bristlecone pines rank as the oldest trees in the world and have achieved immense scientific and cultural importance.
Nearby Attractions
Head to the neighboring John Muir Wilderness for incredible views of Palisades Glacier, the southern-most glacier in the country. Nearby Tinemaha Reservoir provides additional fishing opportunities.

FAQ
How do I get a reservation at Upper Sage Flat?

Campsite Sniper has also detected 108 site openings here in the last 90 days, so further dates may appear. Pick a site on the map to see its calendar, or set a free Campsite Sniper alert. You complete the reservation yourself on Recreation.gov.
Does Campsite Sniper book this campground for me?
No. Campsite Sniper sends alerts and direct Recreation.gov links. It never books, pays for, holds, hoards, or resells reservations.
How current is this availability data?
Campsite Sniper re-checks public Recreation.gov availability for this facility every hour and republishes whenever anything changes. This facility's data last changed at Nov 2, 2026 21:20 UTC; an older timestamp means nothing has changed since that time, not that checking stopped. Always confirm final availability on Recreation.gov when you book.
How often do new openings appear at Upper Sage Flat?
Campsite Sniper detected 108 site-date openings here over the last 90 days, none in the last 7. A free alert watches around the clock and pings you the moment one appears.
Can I get a multi-night stay at Upper Sage Flat?
18 three-night openings are showing, counting only runs where the SAME site is free for all three nights. The soonest starts Apr 16, 2027 at site 002. Confirm and book on Recreation.gov.
Which sites at Upper Sage Flat fit a 35-foot RV?
14 of the 18 sites that support RV analysis have a recorded maximum of 35 ft or more; the longest recorded is 45 ft.
Which month has the most availability at Upper Sage Flat?
April 2027, with 267 open site-nights in the current snapshot of 300.
How far ahead of a stay do openings appear at Upper Sage Flat?
Half of the openings Campsite Sniper detected appeared at least 9.5 days before the stay date; the middle 50% landed 4-19 days out. Campsite Sniper can monitor future changes for dates you select.
When is the next open date at Upper Sage Flat?
Campsite Sniper cannot answer that from the current snapshot. The availability data held for Upper Sage Flat begins Apr 16, 2027 — about 165 days after this snapshot was taken, so any earlier dates are outside what Campsite Sniper is tracking here rather than known to be unavailable. Check Recreation.gov for dates before Apr 16, 2027.
