First of all, thank you for your invitation!
Because you don&;t have very clear conditions, climbing mountains is not recommended for parent-child tours. Let me give you a brief recommendation on tourist destinations in Guangdong:
Conghua, Guangzhou: Shimen Forest Park, Liuxihe Forest Park (these two forest parks have beautiful scenery and flowers), Tianshi Cherry Blossom Paradise (mainly looking at cherry blossoms), Xitou Village and Qianlonggou Waterfall;
Guangzhou Huadu: Huadu Vanilla World, Baosang Garden (you can pick mulberries), European Town of Jiulong Lake (free tickets, European-style architecture, excellent photo spots) and Hongshan Village;
Panyu, Guangzhou: Yuyin Mountain House, Maodegong Caotang, Gull Island and Lianhua Mountain;
Nansha, Guangzhou: Million Sunflower Garden, Nansha Wetland, Waterbird World, Jiujiuyong;
Foshan: Lingnan Xintiandi, Zumiao and Liangyuan;
Shunde: Qinghui Garden, Fengjian Water Town and Changlu Farm;
Shenzhen: East OCT Chaxi Valley, Big and Small Meisha, Jiaochangwei, Xichong, Guanlan Printmaking Village and Gankeng Hakka Town;
Zhaoqing: Qixingyan and Guangning Bamboo Sea;
Zhongshan: Sun Wen Park, Zhanyuan, former residence, Zhongshan Film and Television City (I go to Zhongshan once a month, which is a very leisure city with delicious squab and crispy meat);
Zhuhai: Shijingshan Park and Chimelong Ocean Kingdom, or you can take a boat trip to Dong &;ao Island, Wailingding Island and Dangan Island at Xiangzhou Port Passenger Terminal. Seeing the sea from the outer islands is much more beautiful than the land and coastal beaches. In addition, the commercialization of Yuanming New Park is very serious after free admission.
Qingyuan: Yingxi Peak Forest, Yingde Baojing Palace, cattle fish mouth (looking at sparrows), and Field Green World;
Dongguan: Keyuan and Songshan Lake;
Kaiping: Kaiping Diaolou (Zili Village, Liyuan, Majianglong, etc.) and Chikan Ancient Town;
Yangjiang: Hailing Island, Yangxi
