Recommendations please - Camden market for young teens?

[PoptartPoptart]

Thinking of taking DS (13) and DSS (14) to Camden in the summer holidays.
Has anyone got any must see / do tips please?
We will obviously have a wander around the market, but is there anything else we shouldn’t miss in Camden or the surrounding area?

If you’ve got time, take a canal trip on a boat from Camden to Maida Vale. Or you can walk along the canal towpath instead.
