About Heybrook Lookout
Overview
The Heybrook Lookout sits atop its namesake ridge at 1,700 feet. The lookout itself rises 67 feet above the ridgeline and provides spectacular views of breathtaking glacial peaks surrounding the valley. The first Heybrook fire lookout was a simple tent platform built in 1925. The Forest Service replaced it seven years later with a 45-foot log leg tower, with a ground-level cabin intended as sleeping quarters for fire rangers; however, rampant rodents eventually drove the rangers up into the tower where they lived until a 67-foot lookout was built in 1964. Heybrook Lookout is one of only 106 lookouts left in Washington State.
Facilities
The 14 x14-ft. lookout cabin sleeps four and is furnished with one twin-sized bed with mattress, two additional floor mattresses, a table and chairs, propane stove, pot, pan, silverware, coffee pot and battery operated lanterns. A primitive vault toilet is located several hundred feet down the ridge from the lookout. There is a picnic table at the bottom of the tower. There is no water at the site. Guests must bring water for drinking, cooking and washing. Guests must also bring flashlights, sleeping bags, towels, dish soap, matches, a first aid kit, toilet paper and garbage bags. All trash and food must be packed out, and guests are expected to clean the cabin before leaving
Natural Features
On a clear day, guests at Heybrook Lookout see views of Mount Index and Bridal Veil Falls, Mount Baring, Mount Persis and the Wild Sky Wilderness.
Wildlife is abundant, and guests may catch a glimpse of black bears, bobcat, elk or bald eagle. Wolves are making a comeback to the area, but they are usually heard and not seen.
Getting there
Drive U.S. 2 for 2 miles east of the town of Index, just past milepost 37. Limited parking for the trailhead is located on the north side of the highway across from the Mt. Baker-Snoqualmie National Forest sign. From the trailhead, it is a 1 mile hike to the lookout with an elevation gain of 900 feet. Tenants must climb 84 steps in order to reach the main cabin.

FAQ
How do I get a reservation at Heybrook Lookout?
Campsite Sniper's current snapshot shows none of the 3 tracked site-nights open for online reservation at Heybrook Lookout. That can mean dates are reserved, closed, not yet released, or offered first-come, first-served rather than online. 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 22:19 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.
Which sites at Heybrook Lookout fit a 35-foot RV?
No RV-analyzable site here has a recorded maximum of 35 ft or more; the longest recorded is 25 ft.
When is the next open date at Heybrook Lookout?
Campsite Sniper cannot answer that from the current snapshot. The availability data held for Heybrook Lookout begins May 1, 2027 — about 180 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 May 1, 2027.
