Park in the free car park off Westerham Road. Numbered circles on map represent concrete posts bearing red numbers that are part of an old nature trail.
Go up the steps at the south end of the car park and follow path above edge of small valley. Follow waymarks for Three Commons Walk. At a seat on the right, take a waymarked right turn along a broad track that descends into a hollow. Follow the Three Commons Walk waymarks along the valley bottom, bearing left at a junction near the lowest point and then right after a couple of metres. When you reach Fishponds Road go straight across and follow the waymarks downhill to a T-junction. Turn left and cross a bridge to a metalled path passing school on left.
Go through gap on right to children’s playground. Don’t enter but turn right to skirt two sides of playground, emerging in open field at far corner. Go straight across field and take path into woods, bearing right past several numbered concrete posts from old nature trail.
Approaching bottom of path, turn left before bridge and keep left uphill through Padmall Wood. At far end is open space and information board. Take path to right of information board, over duckboards and across stream. Follow path, ignoring right turns, back to stream. Keep stream on right for a while, follow
path sharp left at post “9” then sharp right to cross stream.
Pass concrete post “8” on right and pond on left. Cross stream again and follow track to reach lowest of Keston Ponds. Cross bottom of pond, then turn left along bank of pond and up steps to Fish Ponds Road.
Cross road and follow edge of next pond. At far end of pond, take path between two ponds and at far side turn right along bank of upper pond to Caesar’s Well. Climb steps back to car park.

because of a myth that Caesar
once camped nearby and was short of water

correctly deduced that there must be a source of water there.
Hence the names of both the spring and the river (“bourne” being a
variation of “burn” meaning “stream”).
