Where are the tourist attractions in the suburbs of Beijing more suitable for the elderly?

Mentougou Tanzhe Temple and Jietai Temple, as well as Huairou Hongluo Temple can be used. We just went to Tanzhe Temple on Saturday the day before yesterday. He has 60 passes for Tanzhe Temple and Jietai Temple, 35 passes for Tanzhe Temple and 22 senior citizen cards, but the passes are not available. Jietai I don't know, because we can get the pass, but it should be around 30. In fact, the expressway and 108 or10/national highway are easier to walk, but the mountain road over there in Tanzhe Temple is harder to walk than that in Huairou. Food and accommodation are all in farmhouses, like Tanzhe Temple, where they may be better managed, so the brand of farmhouses is unified, only the store name is different. Wood modeling, yellow primer, green characters. There are also many in Huairou. If the ice doesn't melt completely in April, you can still see the ice waterfall. Of course, you have to climb the mountain. For example, we saw an ice waterfall when we went to Tianchi last week. But these places are mainly in mountainous areas, and it is cold at night. Although they also have heating, they are still far from the city. So when you play, you must bring more clothes. It is best to bring some clothes that are not very thick but can keep out the wind, such as leather vests. Because the wind is hard in the mountains, I can't stand walking from the city, but it's a little hot to wrap thick clothes. Although it is warmer in April, it is better to pay more attention. In addition, the rainbow trout in Huairou must be eaten, and it is best to eat the fish in the local mountains, because some of them are imported from other places, and those are not as delicious as those raised in the mountains, because the feng shui in the mountains is hard, so the skin and meat are very good.
