Travel / Hiking around Zakopane/ Tatra mountains [22]

I am wanting to visit Zakopane in October and do some hiking around the Tatra mountains. I do a lot of walking in England but orienteering isn't my strong point. Is it easy to hike on your own in the mountains, I heard that there are colour coded walks, but then reading the information on the internet it says it's extremely dangerous. Is it safe to hike alone or is going with a tour guide better. If the latter is better does anyone know where you can book onto a tour and how much they are?

Thanks
