This was one of the most impressive sights I've seen. You can walk right up to the edge (no railings) and look down towards the water crashing against the cliff. You're up so high, that the seagulls flying down by the water look like fruit flies.
While it may look more hi-tech pharmacy than candy store, we assure you, all you'll find in here are sweets. You do, however, get to put all your goodies in a pill jar and label the contents. And no, we don't think insurance will cover this.
One of the best hostels in Europe, if its still around is called 'the Kabul' - Its about 500m from the bottom of Las Rambas in a small square offshoot path. This was the best hostel for fun & meeting people! Highly recommend it!
