Desolation Wilderness Permit — Pyramid

Pyramid Creek (Twin Bridges) trailhead: what makes it different

Pyramid is the Pyramid Creek (Twin Bridges) trailhead off Highway 50, the door to Horsetail Falls and, past it, the off-trail lakes of zone 44. It is not a zone and sells no permit of its own: you book the zone you will sleep in on night one, and from this trailhead that is usually 44, 40 or 33.^4,6,5

Getting to the start

The Forest Service puts the trailhead on the north side of U.S. Highway 50 near Twin Bridges, 41 miles east of Placerville. Its page lists a flush restroom, day use from sunrise to sunset, closed in winter, and a $10 day-use fee for parking. The page was last updated March 23, 2026.⁵

The page's current-conditions line adds that the lot gate was open and that no day-use permits or payment were needed at that time. That sits oddly beside the $10 fee line on the same page, so call the Placerville Ranger District at (530) 644-2324 before relying on either. The Outbound's Ropi Lake page quotes $5, with reviews dating from 2016 to 2025.^5,10

Recreation.gov lists Pyramid Creek (Twin Bridges) as one of 17 trailheads on the Desolation permit. It is an entry point on the itinerary, not a product, so the permit is sold by zone.⁶

The first leg

The Forest Service table gives four stops from this trailhead: Horsetail Falls (base) 1.5 miles, Avalanche Lake 1.8, Ropi Lake 2.0, Lake of the Woods 3.6, and the Pacific Crest Trail at 4.3 miles. The first three are in zone 44, Lake of the Woods in zone 40 and the PCT in zone 33. Everything past the falls is rated difficult.⁴

Live and Let Hike describes the start: a lot with room for 50 or more cars, the Pyramid Creek Loop Trail winding east and north, a first stone slab by the creek after roughly 250 yards, and the start of the loop at 0.3 mile. The track gets hard to follow once slickrock replaces dirt, with only sporadic black blazes. The wilderness boundary and a sign-in register come soon after the 0.9-mile mark.⁷

Terrain and difficulty

A volunteer wilderness ranger writing for Sierra Rec Magazine says the trail turns from easy to moderate to hard as you go, and that so many social trails cross the approach to the falls that the safest rule is to keep the creek close on your right.⁸

The Outbound's Ropi Lake page counts about 4.87 miles out and back with 1,581 feet of gain on its map, and the text speaks of roughly 1,900 feet and a lot of scrambling on big boulders. A 2018 reviewer there says the hike to the lake is about 3 hours but to allow 4 or more.¹⁰

The Caldor Fire in 2021 burned the forest around the trail. Live and Let Hike saw charred pines along much of the walk in July 2023, and Sierra Rec Magazine records a 2022 closure under Forest Order 03-22-06. The Forest Service page now shows the site open.^7,8,5

Quota at this entry point

• 2026 daily quota at Pyramid Creek (Twin Bridges) trailhead, overnight, zone 44 (Avalanche): 20 people a day. The Forest Service table splits the 20 into 14 advance and 6 walk-in. It prints no year. Zone 40 Lake of the Woods is also 20, and zone 33 Aloha is 36 (25 advance, 11 walk-in). This trailhead has no quota of its own.^1,6

Rules specific to this entry point

Recreation.gov describes zone 44 as an off-trail area reached from the Pyramid, Ralston or Echo Lakes trailheads and primitive routes. It covers Horsetail Falls, Avalanche, Pitt, Ropi, Osma, Toem and Gefo lakes.⁶

Your first night must be in the zone on your permit. A trip that starts here and ends the first day at Lake of the Woods needs a zone-40 permit, and one that reaches Aloha needs zone 33.^2,4

Where it leads

Avalanche and Pitt lakes sit just above Horsetail Falls. Sierra Rec Magazine calls Ropi its favorite lake in Desolation, with Pyramid Peak reflected in it and a sky open enough for night views, and says Desolation Lake above Ropi sees few visitors.⁹

The Forest Service gives 2.0 miles to Ropi, a fifth of a mile past Avalanche. The Sierra Rec trail article says Ropi lies about a mile beyond Avalanche, so the on-the-ground walk is longer than the table suggests. Both agree there is no trail past Avalanche and that staying within sight of the creek works.^4,8

What trip reports say

Live and Let Hike's July 2023 day trip passed a swimming pool near 1.5 miles, then a twisting 20-foot cascade that marks the ill-defined base of Horsetail Falls. It calls the stretch a moderately strenuous half day.⁷

A 2016 reviewer on The Outbound's Ropi page says climbing Horsetail Falls is one of the most exciting ways in. A 2025 reviewer says the route needs some scrambling and the path is hard to stay on.¹⁰

Sierra Rec Magazine's Pyramid Creek piece stresses route-finding and off-trail scrambling beyond the falls, and says miles are easy to add while picking a line across open granite between Desolation and Channel lakes.⁹

When to go from here

The lot is closed in winter, and creek flow thins in a dry year; the 2023 write-up notes the creek can shrink to a trickle in late summer in a dry year.^5,7

Compare with nearby entry points

• Avalanche: Avalanche (zone 44) is the permit that goes with this trailhead's own lakes, 1.8 miles in, 20 people a night.^4,1
• Lake of the Woods: Lake of the Woods (zone 40) is 3.6 miles from the same trailhead, also 20 people a night, with marked campsites on the north and east sides.^4,1,3
• Ralston: Ralston (zone 45) has its own trailhead and a steep trail; Recreation.gov also lists Ralston as an approach to zone 44, so the two trailheads feed the same lakes.⁶
