Cornwall's tourism leaders will press a government minister for assurances about the industry's future on Tuesday.
Attractions like Eden have boosted the county's tourism industry
They will urge the tourism minister, Kim Howells, to back calls for more investment in the county's road and rail network.
Mr Howells is spending two days on a fact-finding tour of Cornwall and the Isles of Scilly.
His tour of Scilly included visits to St Mary's, Bryher and Tresco.
On Tuesday he is meeting members of the Cornwall Tourism Forum at a meeting in Redruth.
Members of the forum say they want to question Mr Howells on his support for greater government investment in Cornwall's road and rail links.
There is also concern about the future of Newquay Airport, particularly following an announcement by British Airways (BA) that it is to pull out of its flights to Gatwick in October.
Last week, the owners of Plymouth Airport, Sutton Harbour Holdings, announced they were intending to set up a new airline to operate flights from the South West to Gatwick when BA does pull out.
However, talks with BA are still ongoing over the project.
There has been a revival of Cornish tourism in the last few years, which has been helped by developments like the Eden Project and the National Maritime Museum in Falmouth.
Tourism bosses also say that an increase in concern over flying to international destinations because of terrorism worries have also helped bring more people to the county.
Malcolm Bell of South West Tourism said:
"It is great to have Kim Howells visiting the region.
"He will be fully updated on the current state of tourism in Cornwall and the Isles of Scilly."
