Sweet Grass Adventure (ルオムの森 スウィートグラスアドベンチャー)
This outdoor park in Kitakaruizawa, Naganohara Town exists in natural harmony with its surroundings. There are two athletic courses inside the forest that can be enjoyed while wearing a harness, allowing visitors to feel close to nature while taking responsibility for their own safety and independence, helping them to develop as people. The courses are equipped with paths as well, so you can enjoy them without participating in the athletic portions. There’s also non-harness playground equipment for preschoolers.

Review of Sweet Grass Adventure
TripAdvisor Traveler Rating小学校から有料のアスレチックスが楽しめます。幼稚園児はトランポリン(有料)があります。
電話やオンラインで予約したほうが良いです。ハーネスをつけレクチャー後やるので安心して楽しめます。
ワイヤーを使ったジップライドが楽しめます。ハーネス(安全装置)があるので心配ありません。
森の中の自然を満喫しながらのアクティビティ、お薦めします。

Gunma Areas

Gunma prefecture is synonymous with onsen. Natural hot spring water sources throughout the prefecture have given rise to a series of small onsen towns, each set among luscious mountains. At Kusatsu, Ikaho, and Minakami, traditional indoor and outdoor bathing experiences are served hand in hand with irresistible onsen-themed food, including steam-cooked eggs and custard pudding.
