YOGYAKARTA, Indonesia-Hundreds of tourists, many of them young Westerners, sat on gray stone steps atop the world's largest Buddhist temple, occasionally checking cellphones or whispering to each other as they waited for daylight.

Sunrise wasn't spectacular on that recent summer day. But even an ordinary dawn at Borobudur Temple-nine stone tiers stacked like a wedding cake and adorned with hundreds of Buddha statues and relief panels-provided a memorable experience.

The ninth-century temple is in the center of Indonesia's Java island, a densely populated region with stunning vistas. Other highlights include the towering Hindu temple complex of Prambanan-a UNESCO World Heritage site, like Borobudur-and Mount Merapi, the country's most active volcano, whose lava-covered slopes are accessible by jeep.

While the two temples draw many visitors, other foreigners head to the relaxing beaches of Bali, just east of Java and by far the most popular tourist destination in a nation of thousands of islands and almost 270 million people. More than 6 million tourists visited Bali last year, or about 40 percent of 15.8 million visitors to Indonesia overall, according to official figures.

Recently re-elected President Joko Widodo wants to change this dynamic by pushing ahead with"10 new Balis"-an ambitious plan to boost tourism and diversify Southeast Asia's largest economy.

Key to the plan is to upgrade provincial airports and improve access to outlying destinations, such as Lake Toba on Sumatra island, more than 1,300 kilometers from Jakarta, the capital. Yogyakarta, the provincial city from where visitors head to Borobudur and Prambanan, is getting a second airport that's expected to be fully operational later this year.

Muslim tourists, including those from the Middle East, may also be an easier fit for some of the more conservative areas earmarked for tourism development. Tourism officials have played down the possibility of cultural friction that might accompany the influx of more non-Muslim visitors, arguing that Indonesia's brand of tolerant Islam can accommodate everyone.
