For our trip, getting some sun and saving MONEY was the objective, so we kept the hotel on the cheap side (and 30 minutes away from the beach). That wasn’t a big deal though since we were able to check out a little history on the way (about the area of Kyotango and how it developed from its own ‘kuni’ into the area it is today).
While the small and intimate beaches of Kyotango don’t require much, I would definitely recommend some beach/water shoes. Most of the shore is covered with rocks covered in sea veg, so it can be quite slippery. This also means that there is quite a bit of sea life underfoot, so be careful not to step on anything cute or dangerous.
