Al Suhub – a mountaintop destination overlooking Khor Fakkan – drew at least 50,000 people over the holiday, state news agency Wam reported.
Almost 600 metres above sea level, the observation point offers panoramic views of the UAE’s east coast and the Gulf of Oman.
Sheikh Dr Sultan bin Muhammad Al Qasimi, Ruler of Sharjah, opened the venue last month.
Ayman Al Naqbi, director of planning and surveying in Khor Fakkan, said the number of people visiting the city had doubled in recent years because several tourist attractions had opened there.
They include a Roman-inspired amphitheatre and huge waterfall, which opened on the Corniche last December.
A new heritage area with a canal, hotel and traditional-style souq has also come to life, and trails are being constructed to encourage hiking.
One three-kilometre mountain path leads walkers to the recently redeveloped Rafisah Dam. A second route, once complete, will reach Jebel Al Sheikh Tower.
