Private event venue · Highline Summit House · Buellton, CA
A mountaintop estate for your event.Offsites, retreats, celebrations and dinners — on 1,200 private acres.
The Summit House sits at the highest point of the ranch, on top of California's biggest ziplines. Tell us the group and the day you're picturing; we price the adventure now and follow up with a venue proposal.
The venue
One estate. Nobody else on it.
The Summit House is a furnished four-bedroom house at the top of the Highline ranch on the mountain above Buellton — timber beams, a stone fireplace, windows on three sides, an infinity pool and a terrace with the whole Santa Ynez Valley laid out below. Below it: a lake with a lawn, a ridge-top zipline platform, and 1,200 acres with no one else on them.
It's private and yours for the day or the weekend. No fixed hours, no noise cut-off, no other event down the hall — and the ziplines and Adventure Park are a shuttle ride away for the group.
The spaces
Use one, or all of them.
-
The grand room
Timber beams, stone fireplace, windows on three sides. Seated dinner or a working session for 100 or more.
-
Pool terrace & deck
Cocktail hour, breakout space or the after-party. Outdoor dining, the fire pit, and the view from every chair.
-
Summit lawn & lakeside lawn
The summit lawn for a reception; the lakeside lawn below for ceremonies and gatherings of 300 or more.
-
Summit zipline platform
The highest point on the ranch. Group photos, a sunset toast, or the first flight off the top for the whole team.
What it's for
Offsites, celebrations, and everything in between.
Corporate offsites & retreats — a working morning in the grand room, ziplines after lunch, dinner on the terrace, and the team asleep on site if you take the weekend. Team building days that end with a real meal instead of a parking lot. Milestone birthdays, reunions, anniversaries with the family staying at the house. Private dinners for 100+ with the valley as the backdrop. Weddings have their own page — Wedding Celebrations.
Highline is the venue, not the planner: you bring your caterer, bar and vendors (we'll give you names of the ones who know the mountain), we keep the estate ready, help with setup and clean-up, and run the shuttle from base camp.
