It is an adventure mini-golf course that is being built on an old silver mine. The entire mini golf course is built in an Indiana Jones look (if necessary, check on Google). The central figure of the logo is a donkey (Gruben Donkey), which has a lamp on its head (see appendices). If necessary, a palm frond could be integrated into the logo, as there will later be palm trees on the square.
The donkey/logo should be appealing to young and old. And ideally the logo should be well produced for later advertising materials. So don't include too many details.
Alternatively, the donkey should also be able to be integrated into the golf club's existing logo. See logo in the appendix.
