Here's an advice I've learned by experience. Indeed, many of us have a hundred ideas before the morning shower, and we often start working on some of them. But to have any chance of success, what you really need is a domain expert.

This means that, in this particular example, you need someone who has experience at least with tourism in general, and ideally with adventure tourism and similar activities in specific. Also, they need to be able to think out of the box and explore new possibilities in their trade.

Ideally, this means that you're working in an area YOU know intimately yourself, or barring that to have an expert for a co-founder. If you don't, you'll have to learn the basics and make the rookie mistakes which an expert would avoid.

When you look around, you'll notice that there are very few success stories that were started without an expert in the field. Off the top of my head I can think only of AirBnB, and they keep running into basic level situations like trashed apartment and the like.
