Thailand Trip 2 weeks jungle, beach, adventure

Hello I am Anna, 34 years old and looking for this way travel enthusiasts from 18 to 100 years. Mainly I would like to travel with girls, as a kind of women's trip. The travel costs would be in high season with hotel accommodation, meals, about 4 excursions, and all flights generously calculated at about 1500, - per person. It goes of course even cheaper if we live in hostels e.g. The exact date is not yet fixed and the route is based on my Internet research, that is, it is also not fixed, serves only as a suggestion. The price here is based on mid-range hotels, I don't mind going to the land of adventure as a backbacker with hand cookies and hostel accommodation/camping. I love the outdoors, just sightseeing should come first. Seeing a lot, living out activities that is my focus and also the biggest spending point. We are welcome to rent a scooter, or a car. To the route also fits a trip to Koh Tao. Since I still have 17 days of vacation, I would like to travel to Thailand. The trip would look like this: Outbound flight to Bangkok and return flight from Phuket or also Bangkok? 1. flight from Germany to Bangkok 2. arrival in Bangkok and some sightseeing, later we fly to Chiang Mai and stay overnight there. 3. excursion to Chiang Rai (white temple, raft trip etc..) back to Chiang Mai and another overnight stay there. 4. flight to Phuket, and from here with a cab to Khao Lak (or alternatively by ferry to Krabi and Tiger Cave, overnight here and next day to Khao Lak?) 5. in Khao Lak we will stay until the end of our trip, because from here start pretty cool trips like: Koh Pi Pi with Viewpoint 2 and Monkey Island (Maiabay we see only from afar, because closed), Similan Island, Khao Sok National Park with boat trip, possibly overnight stay and elephant bathing, Kho Kut, Sandy Beach, Coconut Beach etc.... The return flight is from Phuket. By the way, I travel only with hand luggage, because I get better from A to B that way. Hotels are not very important to me, because I am more on the road, and look for my peace on the beach when I need it. Have I made you curious, then get in touch. I would be very happy. 😊
