The club
A course gets you started, and the club keeps you jumping
Good BASE jumping comes down to preparation, judgement and the people around you. The club brings training, mentorship and trips together, so you keep learning after you go home. Membership is £50 a year, free for 12 months with our FJC, Big Wall Course and Wingsuit Camps.
An active community
Members-only group chats where jumps get organised, from easy days out to bigger missions. Finish your first jump course and you’ve got a crew to jump with.
A private database of exits
Buildings, antennas and the odd objects that never make it into public guides. Normally you only hear about these once you know the right people. Members get them in the database.
Also included
- Shop discounts
- Partner discounts
- Club gear to borrow
- Early access to trips
- Mentoring as you progress
- Merch each year
Courses
Wherever you’re starting from
Every course runs in small groups with our lead instructors, and they all teach the same way.

Read the full review by Adrian C.“Having completed the course, I feel competent, confident, and proficient to jump without instruction. This is what the team wanted to achieve. I write this while still attempting to reconcile what is - to me - a life changing experience, with everyday life. I cannot express my level of satisfaction with the team and the course; any superlative will be an understatement. Highest recommendation.”

Frequently asked questions
If you can’t find the answer you’re looking for, drop us an email team@letsmakestupiddecisions.com or find us on Instagram @letsmakestupiddecisions.
Is BASE right for me?
Be clear-eyed about this one: BASE jumping can kill you or injure you badly, and no amount of training takes that away. What training does is give you the skills and the judgement to make better decisions, and a club around you means you keep making them long after the course. If you are weighing it up, talk to us. We would rather have an honest conversation about whether now is the right time than sell you a course.
What experience do I need?
There is no magic jump number. We start with a conversation about what you have done, where you are strong and where you are not, and then either tailor the course to you or tell you what to work on first. If that means saying not yet, we will say it.
Where do I start?
If you just want to find out what BASE is like, start with an Intro Jump in the UK: one jump with an instructor, about three hours, no rig and no course commitment. If you already have the skydiving background and want to learn to BASE jump, the First Jump Course is the place to start. If you are not sure which of the two fits, tell us what you have done and we will give you an honest answer.
What is the difference between the First Jump Course and the Big Wall Course?
The First Jump Course is where you learn to BASE jump: ground school, gear, packing and your first slider-down jumps, so you go home able to jump safely and independently. The Big Wall Course is the step up that comes later: slider-up tracking, big wall exits and alpine canopy flight in Brento and Lauterbrunnen. If you want to do both in one trip, the Complete BASE Course runs them back to back.
Where do your courses run?
First jump courses run in the south of France, big wall progression in Brento in Italy and Lauterbrunnen in Switzerland, and intro jumps in the UK. Private coaching and bespoke trips can run wherever suits what you are working towards.
What happens after my course?
This is the part that matters most to us. Your instructors stay available after the course, and our First Jump Course, Big Wall Course and Wingsuit Camps come with 12 months of free club membership, so you have people to jump with, mentoring as you progress and a way to keep learning once you are home. A course on its own leaves you with a handful of jumps and nobody to do the next ones with.
What does club membership cost, and what do I get?
Membership is £50 a year, and it is free for 12 months with our FJC, Big Wall Course and Wingsuit Camps. It gets you into the members-only chat groups where jumps get organised, our private database of exits, discounts in the shop, partner discounts, club gear to borrow, learning resources, mentoring as you progress, early access to trips and club merch each year.
Can I join the club if I already BASE jump?
Yes. You do not need to have done a course with us. Plenty of members learned with us and plenty learned elsewhere; the club is open to jumpers whoever taught you and wherever you jump. It is £50 a year either way, and free for 12 months if you do our FJC, Big Wall Course or a Wingsuit Camp.
Can I be coached one to one instead of on a course?
Yes. Private coaching gives you a lead instructor to yourself for a private first jump course, private big wall progression, or a trip built around your own goals. Get in touch and we will put something together.
Not sure where you fit?
Tell us what you’ve done and what you want to work towards, and we’ll give you an honest answer, even if it’s “not yet”.
