Adults only · 21+ · Up to 300 guests
Private Events, Birthdays & Celebrations
A hilltop with a view of the whole west coast, an adults-only terrace, and a kitchen that will build the menu around your table.
What we can host
Small groups
Six to twenty guests at a long table, without taking the venue. The simplest option and the one most birthdays end up choosing.
Full private booking
Up to 300 guests with the whole hilltop to yourselves — the terrace, the pool deck and the view.
Anniversaries & proposals
A private table timed to sunset. See romantic dining.
Planning it
How many people can you host?
Up to 300 for a full private booking, or 6–20 as a group within normal service. Tell us your numbers and we will be straight with you about what the space does well.
How far ahead should I book?
Two weeks is comfortable for a small group. For a full private booking, or anything between November and March, give us a month if you can.
What about the menu?
We build a set menu around the group — fully plant-based, seafood, or both. Dishes run THB 150–520, and we will give you a per-head figure before you commit. See the current menu.
Deposits
For private bookings and larger groups we take a deposit. We confirm the amount and the cancellation terms in writing when we take the booking.
One thing worth knowing
Secret Mountain is adults only, 21 and over, and that applies to private bookings too. We would rather say it now than at the door.
