While there is a small beach right in the city center (just go down the stairs from Komsomolskaya square), crowded during nice days and with a few people bathing in the river, swimming in Amur is really not recommended. The water in the river is polluted mainly from chinese side and can cause really serious diseases...
I would be careful when buying things from street vendors.... I cannot really justify that, it is just my personal opinion! Still it is incredible to see, what kind of things people come up with to sell!!!
There are no free public toilet rooms in Khabarovsk, thus it's recommended to use the toilet rooms at the hotels and restaurants
The toilet rooms at the railway station, open market and museums are chargeable.
Please, always carry some small change (about 5 rubles) to make the payments at the toilet rooms if needed.( Toulet paper isn't free : ))) Just kidding)
It is a known fact that public safety is much better in Khabarovsk than in the other Russian cities.
keep an eye on baggage;
do not walk down the uninhabited streets;
do not make friends with the carefree people;
do not ever show your wallet to strangers;
lock the hotel room every time you are out;
keep all valuables in the locked baggage or at the hotel safe box.
At the overcrowded locations like stations, markets etc there can be pickpockets thus I advise to be extremely careful and watch your wallets, cameras and other valuables : ) Take care
The water in Khabarovsk is rather hard enough thus I advise not to use it if not boiled.
Mineral water is always available at store or at hotel lobby. Whenever you are shopping for mineral water, do not forget to ask a salesperson for a non-carbonated mineral water ; ))
Taxis in Khabarovsk do not have meters nowadays. Agree on the price before getting in.
To get from the Intourist hotel to the downtown of Khabarovsk may cost you about 50 roubles (US $ 2). Though the prices are low, to flag down a taxi in the street might be a problem.
There are very few foreigners in Khabarovsk, so it is wise to stay out of the markets or shopping areas during the holiday rush. I have been escorted from shopping areas by the military who have warned me of the threats on foreigners. Even if you are with Russian citizens, it is better to plan around this and visit friends instead.
Keep in mind that in Russia (especially Khabarovsk) the traffic police are suspect. Traffic police patrol areas by "observing" traffic. If they feel you are breaking a law, they will simply wave a black and white striped baton at you and you must stop your vehicle. At this time they will explain what you did and you must pay on the spot. The police will decide how much you will pay.......
Be careful if you drive... Slow and deliberate is the best.
Beware of taking things i.e. as paintings and other things I was given an oil painting by one of the locals,he'd painted himself,the real screwy thing, I was handed the painting at the airport. An official told me I had to pay so many hundreds of rubles in order to take it with me to th States,about 75.00 American dollars and I didn't think (no offense to the artist) it was worth it. I was also warned about the water BYOW, not to eat dairy products,and by all means keep your money and jewelry closely concealed.
Winter time is cold here. It can be more then -25C with a cold northern wind. So I just recommend you to take warm, very warm clothes... if you are not planning to get cold...
