A certain Big Island mountain with telescopes has attracted a whole lot of attention over the past few weeks. Go to our homepage and type “Mauna Kea” or “TMT” into the search window for a refresher.

Meanwhile, the other Hawaii mountain with telescopes — Haleakala on Maui — will be featured in the CW channel‘s “Rock the Park” series Saturday. It’s the premiere of “Haleakala: In the House of the Sun.”

On April 25, the program will premiere “Hawaii Volcanoes: Trekking Mauna Loa,” the sister mountain to Mauna Kea.

Jack and Colton prepare to bike down the side of the world’s largest dormant volcano at Haleakala National Park.

Tremendous! Entertainment

In the 30-minute show, hosts Jack Steward and Colton Smith take viewers “on an adventure to the country’s most popular national parks, coming face to face with nature and some of the most awe-inspiring places on earth.”

The premiere of the Hawaii episodes coincides with National Park Week, America’s “largest celebration of national heritage,” April 18-26.

The Hawaii Visitors and Convention Bureau, which is contracted by the state’s Hawaii Tourism Authority and paid for through the hotel tax, assisted with the production.
