Some of the most valuable parts of our visitor offer are the things we cannot manufacture.
The landscape is one. Our communities and sense of place are another.
And when darkness falls across Bannau Brycheiniog (Brecon Beacons) National Park, we have another remarkable asset above us.
Bannau Brycheiniog is an International Dark Sky Reserve, recognised internationally for the quality of its night-time environment.
That matters environmentally.
It also matters to tourism.
Tourism businesses spend a great deal of time thinking about what visitors can do during the day.
Dark skies extend that thinking beyond daylight hours.
A visitor who has walked, explored a market town or visited an attraction during the day can eat locally in the evening, return to their accommodation and still have another experience waiting outside.
There is no opening time required for a clear night sky.
For accommodation businesses in particular, that gives us an extraordinary reason to encourage an overnight stay.
Camping and glamping sites, self-catering properties, inns, hotels, farm stays and rural accommodation can all form part of the Dark Sky experience, alongside specialist astronomy and astrophotography providers.
Visitors can already explore Dark Skies in Bannau Brycheiniog, find places to go stargazing and choose somewhere to stay through the destination website.
Specialist local businesses including Dark Sky Wales and Serydda also help turn the night sky into a bookable visitor experience.
It is a good example of the tourism and hospitality eco system working together.
The experience itself may be looking at the stars, but the economic benefit spreads much further: accommodation, food and drink, local shops, activities and the communities in which visitors spend their time.
Dark Sky tourism also becomes increasingly relevant as we move beyond the main summer holiday period.
August begins giving us noticeably darker evenings. Autumn brings longer nights while the landscape itself changes colour and pace.
That creates an opportunity.
Instead of seeing the end of the summer holidays as the end of the visitor season, we can begin changing the story.
Come for the walking.
Come for the food.
Come for our towns, independent businesses and autumn landscapes.
Then stay for the stars.
The same journey that might have been a summer day trip can become an overnight or two-night break when the evening itself is part of the reason to visit.
Visit Wales also promotes Bannau Brycheiniog as one of Wales’ key destinations for Dark Sky holidays, reinforcing the opportunity for businesses to build this into autumn and winter visitor messaging.
Of course, we only retain that advantage if we look after it.
Dark skies depend on darkness.
Reducing unnecessary light helps protect the night-time environment and wildlife as well as maintaining the quality of the skies visitors travel here to experience.
Tourism businesses can play a practical part through thoughtful external lighting, helping guests understand the Dark Sky designation and encouraging responsible behaviour when visitors head out after dark.
It is also about respecting the people who live here.
Quiet rural communities, farms and roads should not become informal viewing sites simply because somewhere looks dark on a map. Good visitor information, appropriate recommendations and responsible parking matter.
That is why directing visitors towards established information such as the Bannau Brycheiniog stargazing guide is important.
There will always be destinations competing for visitors with new attractions, new facilities and new investments.
But some of our strongest reasons to visit already exist.
Our mountains.
Our landscape.
Our communities.
And our night sky.
The current interest around summer meteor showers provides a useful reminder of that. But Dark Skies should not be treated as a short August campaign.
As the nights lengthen, they become part of a much bigger story about autumn and winter tourism in Bannau Brycheiniog: quieter stays, slower travel, good food, walking, warm hospitality and memorable experiences after dark.
For tourism businesses, that gives us something particularly useful.
Another reason for visitors not simply to come for the day.
Another reason to stay.
