Heading to Sweden in May, looking for advice on what to do!

Hello! American here, heading to Sweden for the first time at the end of May. I'm 75% Swedish by heritage, and am looking forward to the visit. I'm a 31 year old single male, making the trip with one of my good friends.

So, as a bachelor visiting your great country, what are some things we need to check out while we are there? I'm not a big fan of tourist traps, tours, etc.

As a side question, if I were looking to bungee jump, where would be the best place for this?

Thanks in advance, and looking forward to the replies!
