Is it really only 10 minutes, could have swore it took us that long to get from the Perelik to the Pamporovo hotel! Would have thought more like 1/2 hr especially in the treacherous road conditions at night.
Firstly in the evening I would not recommend walking from the Malina to the centre. More accidents are caused walking this stretch than actually skiing as it can become very slippery in the evenings, (especially with a few on board!)
To walk it will take you a good 1/2 hour as it is 3 km from the Malina to the Perelik but a taxi for four will cost you about 50p each, well worth it.
Definatly not a 10 min walk - I stayed there with my lot in Feb and had a wicked time. As PP and others say, jump in a cab, only costs pennies..
Great location for the slopes too, no waiting for the buses at all. Best bit though, is that is really close to Markonys for a or several after a day on the slopes.
