A series of meetings were held in 1905 for the purpose of establishing a golf club in Porthmadog and by September 1905 most of the preliminaries suitable land for laying out a nine hole course at an estimated cost of £80, provided this amount could be promised in subscriptions. Construction of the course commenced in March 1906 and by the end of May was considered ready to play. The club became known as the Porthmadog and Borth y Gest Golf Club, with subscriptions for the first hundred applicants at a half guinea up to 30th June and one guinea for those who joined subsequently. The ladies subscription would remain at half a guinea. After a summer of play during which handicaps were allotted the first competition was held in November 1906.

Much interest has been taken in the first handicap medal competition at the Borth y Gest golf links. some of the beginners have taken the starch out of the old hands. This first handicap was very successful and is likely to lead to a sensible increase in the membership. The play showed that the Handicap Committee had done well; the shortest handicap man tying with the longest handicap man for the first place.

 The leading scores were
A.C. James 88 . 10 - 78
D. Davies 103 . 25 - 78
D.Ll. Hughes 99 . 20 - 79
E.R.V. Thomas 105 . 25 - 80
N.C. Percival 98 . 18 - 80

The land at the disposal of the club extended to some 45 acres on an annual tenancy from Hugh Thomas Hughes of Garreg Wen Farm, until June 1910 when a tenancy agreement was signed. Stipulations made in the agreement suggested that golfers must be on their best behaviour, and in particular not to take any game, hares, rabbits or wild fowl; were not to be accompanied by a dog, and were to pay compensation for any sheep, cattle or other animal killed or injured by them. They were not to play on Sunday, nor diminish the level of water in Llyn Samson. The landlord in turn was to continue to enjoy grazing rights for sheep, cattle or unshod horses, but was not permitted to turn on to the land any bull or other savage cattle.

For four years, a small out house at Ynys Cyngar served as a club house. The first building was a hut for Evan Jones, the professional who had been appointed in 1908. This wooden hut was located near the then ninth green (present 15th) a few yards from the acre of land in the centre of the course on which Evan Humphreys was building his imposing house, Gwynfa, and a golf club house in use by 1912, let to the club by Mr Humphreys. That year the work force was doubled by the addition of Griffith Ellis (aged 15) at a wage of half a crown a week, to help Evan Jones carry out his duties of cutting greens and tees, filling sand boxes, repairing clubs, teaching beginners, maintaining fences around the greens, or at the request of members, playing a round with them.
