There is an international airport in the near town of Wroclaw.
The Polish State Railways  has train connections from Wrocław but since 1997 the connection to Świdnica (In fact anything via) has been halted. Trying to find the closest neighbouring station is not feasible as you can get a private or public bus much cheaper. Ther has been talk about a private rail bus to connect Wroclaw and Świdnica for years.
From Wroclaw Intl you can get the airport transfer bus that will take you to "PKP" (Polish Rail Network). Walk through the PKP tunnel, cross the road and you will walk up the stair straight into the Main Bus station. You can wait for the PKS buses on Platform 1 (really old public buses) which are cheaper but take about and hour to arrive to Świdnica. On Platform 2 (Counting from the main building) You will most certainly spot several private buses signed Swiebodzice / Wałbrzych that cost slightly more but will get you into Swidnica within 30 minutes.
Many international connections (see Poland::By bus).
The Peace Church (Ksciol Pokojowe) is on the UNESCO World Heritage List- dating from the 1600's and built out of unusual materials (wood and hay), it resembles a theatre or opera house more than a church. Covered top to bottom in beautiful, old, folk-art-style paintings, the Peace Church is absolutely worth a visit.
Behind the Peace Church is an old German cemetery which, as of July 2008, was completely overgrown, giving it a creepy atmosphere and making it a great destination for photographers and seekers of the arcane.
Attend the summer Bach Festival in July. Concerts are held in the Church of Peace and other venues in the town. For further details go to www.bach-cantatas.com and follow the links through 'schedule of concerts' and 'Bach festivals'.
School Youth Hostel 
Castle Książ, near Wałbrzych, is well worth a visit as is the Church of Peace, UNESCO Heritage Site, in Jawor
