Thank you for your question. Jan has already provided a good link to a similar question. However, as you asked for further confirmation:
A visa is not required for many European countries provided that
- your stay does not last longer than three months and
- you do not take up any gainful employment.
Otherwise, a visa is required.
And here is a comprehensive list of states that refugees with a blue passport can enter without a visa:
Switzerland (so yes, you can travel to Switzerland without a visa)
I hope this was helpful.
