It depends on number of people you re going with & services as well.However,keep in mind that it 'd be around 1000$ minimum if you re going along.

or
if we have a budget of Rs30,000 per person so what trekks you guys recommend for us
we are from karachi

I'm interested also in the Baltoro trek... but in September of 2014. Although usually I travel alone, some companion would be welcomed. a bunch of questions:
- Some recomendation about local companies? Looking for booking in advance.
- How harder is Gondogoro La than coming back from the from Concordia using the same trek along the Baltoro?
- What is the situation of the Karakoram Highway like? Thinking about some extra days in the area.

umerio I'm headed to Pakistan in July to do the Baltoro Ghondorgoro La Trek with Snowland Treks and Tours, based in Pakistan. They are highly recommended on this site, and Kamal has been very good at answering my questions. You should check them out.
Although I haven't done this trek yet, going over Gondogoro La will be significantly more difficult than coming back from Concordia using the same route that you took in. It will be more difficult because of the altitude. Concordia is at 4650 m. Gondogoro La is a 5940 m pass. That's a high pass! I've done many passes in Nepal, and most of those are between 5000 and 5500 m. I've climbed Imja Tse in Nepalo, a 6000 m Peak, so I'm confident that I can get over Gondogoro La, but I know it will be difficult. Further, depending on conditions, you may be on a fixed line going over the pass. It's steep and often there is snow and ice.
You can do both, by trekking via Askole to Concordia, K2 base camp and return the same way or to Hushe (ascend Gondogoro la while you're there, a great view of K2, Broad Peak, G series), to reach Khuspang, then down to Hushe and back to Skadru.
Crossing Gondogoro la requires top fitness, prior acclimatization and basic mountaineering skills. The pass is easier to cross and there are objective dangers from crevasses, avalanches and rock fall, which increases substantially as the snow cover begins to melt. The North side is a 50degree snow slope with avalanche danger requiring fixed ropes. South side is also a continuous 50 degree slope, need crampons especially while descending, with rock-fall and avalanche danger. Both ascending and descending sides of the pass have fixed dynamic ropes along with rescue workers at the top of the pass to assist them.
It's not altogether surprising that there are more problems on the Hushe side. Going direct to 5900 metres is a recipe for adverse reactions. Going from the Askole side gives a far better chance of arriving at 5000 metres+ in reasonable shape.
I would highly recommend you get a good dust mask to use in Skardu Askole and on parts of the trail. Once you're above timberline between Askole and EBC, there is no electricity and it's starts to get pretty cold at night, but up there it's more important to have a good layering system in your clothing rather than the finest expedition wear. We trekked at the higher with decent long underwear, fleece and Gore-Tex outerwear and were very comfortable Better to have a good hat, gloves and a neck warmer.
You'll get breath-taking scenery, (and breath-taking altitudes of 5900 metres at Gondogoro la - take it slowly!), the route is not crowded, scenery is magnificent. Either way you're likely to have 'the experience of a lifetime'. Strongly recommend that you book with a local company as your money will go to the local community, will be cheaper, and also possibly better because of the knowledge of the staff and guide.
I've done the same on my trips to Pakistan (including trek to Skardu, K2, G Base camps Gondogoro La and Huseh), last summer is my most recent visit and this year going for Grand Traverse trek. It took me some research, but I finally found a reliable agency and stuck with them.Vertical Explorers Treks & tours -- had great experiences and can’t recommend highly enough, ask for Abbas guide).
