2 nights at lake toya

my wife and i are staying 2 nights in noboribetsu and moving on to Toyako.. We are not sure to stay 1 or 2 nights at lake toya.. what are there to do in Lake toya? We are going mid april..we are looking forward to relaxed trip to slowly enjoy hokkaido nature.

The number of days is more relevant than the number of nights. Two nights could translate in anything between one and three days.

There is not too much to do around Lake Toya itself. One full day (i.e. one or two nights) would be enough, in my opinion. Two nights would give you a base and make it more relaxed.

We spent two nights at Lake Toya, and would agree that there is not much to do there.

In the morning we rented bicycles, and cycled all the way around Lake Toya. Around Lake Toya, there is a series of sculptures, which gives you a reason to stop frequently (to appreciate the sculptures). We got back mid-afternoon, and then my Other Half decided to rent a paddle boat, and went on the water for half an hour. We then went back to our hotel for a relaxing onsen, had dinner, and came out again to see the fireworks.

There are also cruise ships which tour Lake Toya.

There are a couple of volcano sites to visit, and a ropeway that goes up the mountain.

Probably staying one night is enough, and if you want to go cycling, as we did, then perhaps stay an extra night. There is not enough to do there to fill two whole days.
