Nandi Hills, situated around 60 kilometers from Bangalore, is a popular tourist destination known for its picturesque beauty and serene environment. If you’re planning to visit Nandi Hills and are interested in online booking, the steps might vary depending on what exactly you’re trying to book: entry tickets, accommodation, or additional services.

Here are the general steps for booking a visit to Nandi Hills online:

1. Entry Tickets: As of my last update in September 2021, there was no online system for booking entry tickets to Nandi Hills. Visitors typically buy tickets at the entrance. The site opens at 6 AM and closes at 10 PM.

2. Accommodation: There are a few accommodation options in and around Nandi Hills, including the Karnataka Tourism Department’s hotel and various private resorts. To book these, you can:

• Visit the official website of the accommodation provider (like the Karnataka Tourism Department’s website for their hotel) or popular hotel booking platforms like Booking.com or Airbnb.
• Search for Nandi Hills or the specific hotel/resort you’re interested in.
• Select your dates and the number of rooms/people.
• Follow the prompts to complete the booking process.

3. Adventure Activities: For activities like paragliding, cycling, or trekking tours, you can usually book through the service provider’s website or other booking platforms like Thrillophilia or BookMyShow. The booking process is similar to the accommodation booking process.

Remember that while Nandi Hills is open throughout the year, the availability of certain activities might depend on the weather and other conditions. Always confirm the details with the service providers before your visit.

Also, note that online booking processes might have changed or been updated after my last training data in September 2021, so please verify from updated sources.
