和琴半島｜弟子屈を楽しむ｜弟子屈なび｜北海道弟子屈町
屈斜路湖の南側につきでた、和琴半島。かつては火山の溶岩ドームでしたが、大昔に岸とつながって半島になりました。ここは地熱が高く、冬でも凍結しない場所のある不思議スポット。
半島全体は原生的な森に覆われ、北海道らしい豊かさに出合える場所でもあります。
半島の入り口には「和琴フィールドハウス」があり、周辺の自然や地形などについて分かりやすく展示しています。まずはこちらに立ち寄って情報収集するのもよし。
半島にはいたるところから温泉が湧き出ているほか、釣りやカヌー、水遊びなど楽しみ方はさまざま。駐車場脇の土産店では名物の「いも団子」も購入できます。ゆっくりと時間をとって遊びたいスポットです。

川湯温泉（北海道）～日本最大のカルデラから生まれる名湯｜弟子屈を楽しむ｜弟子屈なび｜北海道弟子屈町
ひがし北海道 日本最大のカルデラにある弟子屈（テシカガ）。火山が噴火したくぼみであるカルデラはその特徴から水源豊かな場所となりやすく、弟子屈町を含む屈斜路カルデラは、日本最大であり、周囲に摩周湖や日本最大のカルデラ湖である屈斜路湖などがあることからもわかるように、地下には日本有数の帯水層と水脈が存在すると考えられます。そのカルデラ中央付近には今なお火山活動を確認することができる景勝地「硫黄山」があり、この山の地下マグマで熱せられた湯が地下岩盤層を流れ地上に噴き出してくる場所が「川湯」です。噴き出した湯は温泉街を流れ、屈斜路湖まで注ぎ込む壮大な湯の道をつくっています。
川湯温泉の泉質は強酸性硫化水素を含む明ばん・緑ばん泉、日本でも数少ない火山性特有のもので、自律神経系・ホルモン分泌系の機能を調整して病気を治す力を高め、古い角質を溶かしてお肌をすべすべにしてくれる、『美肌の湯』でもあります。
【泉 質】
酸性・含硫黄・鉄（Ⅱ）－ナトリウム－硫酸塩・塩化物泉（硫化水素型）
