Cyclists paradise

Hokkaido is the northern most island in Japan representing 22% of
Japan’s total land mass and only 5% of its population. It consists of
one large island and 5 smaller islands. There are six national parks,
five quasi-national parks and twelve prefectural parks. Hokkaido is
blessed with arguable the most magnificent natural beauty in Japan.
Furthermore, the relatively cooler climate makes it an ideal get away
during Japan’s sweltering summer. There are four distinct seasons, and
no rainy season.

Camping is also available in many areas, and there have been many
reports of cyclists pitching tents on the side of the road without any
problem. One cycling enthusiast, who toured the country for three
months, reported being invited into people’s homes on several occasions.
With its vast open spaces, many cycling enthusiasts consider Hokkaido
one gigantic cycling course. The best season for cycling is from June to
August.

Sounkyo Gorge (on Hokkaido, where I'm going)
This grand twenty-four kilometer gorge is one of the most awesome sights
in Daisetsuzan. Waterfalls careen off 150-meter cliffs creating a scenic
backdrop to the fiery autumn colors. The best way to explore this area
is by bicycle. The trip only takes about 2 ½ hours, but you are rewarded
with rock walls rising almost perpendicular out of the gorge and
spectacular views around each curve.
