Activities to do in Interlaken

I am going to be in Interlaken for about 6 days in September, and am trying to slot in some different activities for when I am there. I am looking at booking through https://paragliding-interlaken.ch/en/ as they seem to offer so many different options.

At the moment, I am trying to decide if I should do some of or all of these:

- Canyoning Interlaken

- Paragliding and Kayak tour on Lake Brien (combo deal)

- Via Ferrata

- Helicopter Skydive Interlaken

All together, this will cost me approximately $1000CHF.

Am I trying to do too many things? Has anyone done these activities and can help me decide if I should just book them all or should I get rid of a couple?

I would also like to do my own hike or two, depending on how much free time I have outside of these, so if there are any half-day hikes in the area that you would recommend, please do! Love anything with a summit view and a bit of a challenge :)
