The Dark Sky layer on the map shows where it is Bortle 4 or darker, with campsites nearby.

Wait until after midnight
The radiant climbs towards morning and Earth 'flies into' the dust: two to three times more meteors than in the evening.

Look away from the radiant
40–60° from the radiant meteors are longer. Lie down, keep warm, give your eyes 20 minutes without a phone.
