it's an interesting place because it was the only Buddhist temple allowed in the USSR after WWII. In the 1930 all temples were destroyed by the Bolsheviks. So The temple is not old and for experienced travelers may look like kitsch, but historically it is an important one. Also the 'mummy' of one of the old lama's is rather unique. If you go by taxi, arrange one that will wait for you. Otherwise it might be difficult to find one to take you back home at a reasonable price. Taxi apps don't always have cars ready to take you back. There are small buses, but if you don't speak Russian it is not so easy to find one. There is an small open air sport arena and if you are lucky, you'll see some local sport event like wrestling, horse riding or archery.

If for any reason you are in Ulan Ude, which after all, is a really remote place, it is sad if you miss this gem. This may be the best thing, to see in and around Ulan Ude. If you are traveling independently, you may have to get the help of your hotel or the local tourist office to get here, it is about an hour from the city. As an independent traveler, it may be a good idea to hire a vehicle. Budget two hours, once you reach the spot. I was on a group tour, with Sundowners Overland, on the Trans-Siberian, and we were one day in Ulan Ude. The tour operator had organised a guide for our stay in Ulan Ude. She was a local Buryat and she spoke excellent English. As a bonus, she was also a devout Buddhist, so she knew all about this monastery complex. You really need a good guide to show you around, and to explain what you are seeing, otherwise all you do is look at pretty buildings. I say "complex", because it is not just one building, there are many buildings in this vast establishment. This place is the centre of Buddhism in Russia. It has a very interesting history, your guide will be happy to tell you the whole story. Especially the bit about Stalin being nice to Buddhists, etc... Before you go here, it is a good idea to read up something about the place. Wikipedia has a brief entry on it. People in wheelchairs (or people with strollers) ought to have no problems, there are no long staircases anywhere, and the pathways are easily negotiated. Remember, photography is not allowed inside any of the buildings, but you can take plenty of good photos outside.
