Marble run on the beach ☆ Sand hole & mountain nature course. 3 types

This is a summary of the marble run we enjoyed on the beach.
The course uses natural features such as holes and mountains made from sand, and tetrapods with flowing water.
We created the course while being creative in how the balls roll.
Marble runs are a lot of fun to enjoy in the midst of beautiful scenery.
