Walk to Montjuic castle, Barcelona

Montjuic castle is a must go place when you are in Barcelona, its a hill next to the coast line near the Columbus statue at end of La Rambla street. There are multiple ways of going there.

Cable car (teleferic) and Funicular.

Cable car works from the Coast line ot the mountain Miramar and then you can either take bus or walk all the way to Montjuic castle. The ticket cost 7 Euro one way and you can see a very nice view from top specially the coast line, in my opinion its not worth that money as you will finally have that panoramic view from the castle.

the Funiclar is under repair till mid 2016, which was one of the easient way to reach directly to the castle. 

Bus

In place of Funicular there are two buses running all day from station Pral-lel (line 3 and line 2) and Pl.Espanya. the buses are number 150 and also another special bus for Montjuic castle runs every 10 minutes. Before jumping in ask the driver if its going the Castle direction. the T10 card is fully valid in these buses that means its not expensive to go up to the castle as compared to the cable car which cost nearly 7 Euro.

Walking

It might look far but its just 3 km from the coast line by walk and there are planty of places to explore on the way that you will not feel it till the last 300 meter of steep climb :)
Any how I recommend to go at least one way by walking, its worth walking there. it takes nearly 30 min if you go without stopping.

KEEP YOUR WATER BOTTLE ,NO SHOPS ON THE WAY

ASK PEOPLE ON WAY FOR DIRECTION IF YOU DON'T HAVE NAVIGATOR

La Rambla and La Bouqeria, Barcelona

La Rambla (Les Rambles) and La Bouqeria are the famous streets of Barcelona and you just cant skip these two while visiting the city.

Both the street are connected very near to the city center, PL. CATALUNYA. Metro lines L2,L3 and L4 are connected to the Pl. Cataluya but the most near to the street is line L3.

The La Rambla street is full of street vendors and street artist. You can find allot of sellers selling the on ground the fake Football shirts and I recommend not to buy as their average price after bargaining is 12 - 25 Euros and you can easily fin this price in the shops (not the original: it cot 100 Euro from the stadium). The street is a very lively place and a must go in the evening time, keep you luggage and pockets safe as its a crowded place and famous place for pickpockets too.

The street is nearly 1 km long connecting Plaça de Catalunya in the centre with the Christopher Columbus ( which is next to coast line). 

Where as the La Bouqeria is a large food/fish market attached to the Ra Rambla near to Metro station Liceu. The market is just next to the restaurant Dunkin Donut. The market is famous place for both tourists and the locals, especially the fruits,vegetables, chocolates and the marine variety pulls the customers itself.

The market is clean and not smelly( as they sell fish there). Its not very expensive and good experience to meet locals and try some exotic fruits, or just have a lunch in small open stalls.

The freshness, variety, colors and artistic arrangement of products is just indescribable.
