Not just courses. Not just certifications. Real development in a place where high standards are lived every day.
Base One is not built around volume training. We operate primarily as a GUE-oriented hub, while welcoming selected high-level instructors from other agencies who share our standards for preparation, logistics, safety, and meaningful student progression.
The Approach
Learning happens in an environment shaped by real operations, deep experience, and high standards.
Base One gives access to some of Europe’s most distinctive cave-diving systems, with clear water, varied passages, stable conditions, and the right level of complexity for high-quality training.
You enter an operation where details matter and progression is earned, not handed over.
From Fundamentals through advanced Cave and CCR, taught by experienced instructors.
Training tied to active exploration and projects — learning with consequence and context.
Limited numbers mean more water time, more feedback, and a pace that fits you.
Gas fills, boats, classrooms and equipment — so you focus only on the diving.
For people who know that good diving is never accidental.
Course Calendar
GUE courses are booked through GUE.com; other training options can be arranged directly with Base One.
Whether it is your first serious training step or your most advanced Cave, CCR or technical program, the environment here will shape how you grow.
