There is a National Trust car park at the beach close to the Hive Beach Café. Driving the coast road from Weymouth, B3157, the turn off for the beach is at Burton Bradstock, just before you enter the village, look out for Beach Road. There is a bus stop opposite Beach Road which makes it a good jumping off point if you are travelling by bus.
There is a large grassed area ideal for a picnic, and during the summer a National Trust information point. If the post is open, check with the ranger about the local wildlife.
Hive Beach Café is a busy place, with people queuing for a table at busy times. Queuing is not for me so I gave it a miss and enjoyed a picnic. Always take a flask.
It’s a great place to start a walk along the cliff top. The National Trust site has routes to download. I walked the cliff top path to West Bay. It’s probably no more than 2.5 miles, but it does have a couple of steep climbs. And it was a scorching hot day. And I made frequent stops to enjoy the views.
If you don’t fancy the return trek along the cliff you could, after a coffee and ice cream in West Bay, catch a bus back to Burton Bradstock, alighting at Hive Beach. No more than 10 minutes on the bus, but check the bus timetables.
