    道の駅佐賀関から近そうだったのでレンタカーで向かってみました。往路は山の中を抜ける狭く曲がりくねった道路で場所によっては対向車が来たらすれ違うのに苦労しそうです。復路は眺めの良さそうな海沿いの道路を選択しましたがこれが大失敗、山の中の道路以上に狭くて対向車が来たらアウトで2度もバックしました。確かに海沿いで昼間なら景観は良いのですがガードレールが無い箇所もあるので危険です(夜間通行は絶対に避ける...

    昼間なので入場無料でした。夜の天体観測は有料のようでした。展示は小規模ですが、眺めはよいです。10年以上前に一度このあたりに来ているはずですが、あまり記憶に残っていません。併設の食事の場所は営業していないようでした。駐車場は十分な広さだと思います。
