There are many activities unique to the northern peninsula of Ishigaki Island. Horseback riding, paragliding, SUP, kayaking, etc. can all be enjoyed in the vicinity. The nearby beach offers opportunities for snorkelling and yoga. Provided skies are clear, gazing at the night skies from the garden is a must-do activity too.
Of course, activities like reading a book, sleeping, or enjoying wine and awamori all day long are also recommended alternatives for being a bit less active.
