Aragón has the strictest legislation in this regard. I'll summarise what it entails.

When establishing an active tourism company, you must complete all standard business registration procedures – which is substantial in itself – plus the additional requirements to be listed in the Aragón Government's Register of Active Tourism Companies.
- Public Liability Insurance
- Accident Insurance
- Qualified instructors
- Certified equipment for each activity
- Emergency protocols
- Activity dossier
- Additional items depending on your specific activities

Here's the link for verification.
In Aragón, all companies must have a registration number. Request this if you have doubts about a company you're considering, as it shows which activities they're authorised to operate.
While these procedures are tedious, we welcome these requirements as they guarantee minimum safety standards are met.
The problem arises in autonomous communities without such regulations – some only require public liability insurance and a simple form. The disparity is so significant that tourism departments from other regions often consult Aragonese companies about compliance requirements (particularly regarding equipment standards).

As elsewhere, some companies voluntarily meet these standards without legal obligation. That's fine until something goes wrong... but what then? Research thoroughly before booking and choose wisely.
Despite these glaring disparities (we wish all companies had to meet Aragón's standards), Aragón remains the most affordable autonomous community for adventure sports – a striking paradox.

We reiterate: ask every possible question when choosing a provider. Reputable companies will gladly demonstrate their compliance.
*Important! Verify your provider has a registration number like this Aragón Government adventure sports code: TA-HU-124
