Bournemouth Jurassic Coastline Hiking Camping

I am looking for buddies to hike at lowest cost possible , from Bournemouth station along the coastline, swim, look up for fossils, camping for 2 or few days. I am flexible with return day and open to route.

Start is Sunday midday. I’ ll be coming from London taking coach.
You can get ticket for around 19-25£ one way and it takes 3 hours.
Ideally we would spend 3 nights camping and hiking so bring your gear, enough food, water, good shoes and good vibes:-)
