There are quite a few tech spots (centers and dives) in sharm as well; but things tend to be boat based
Dahab is the easier solution, you can’t really just grab a cab and go to dahab (well you can, but that’s not worth it in that way)
Reach out to a tek dive center (most of Dahab) and talk to them about what dive you’d wanna do (your limits allow you the Blue hole arch, the Canyon penetration (note the Deep Exit in the map at the bottom) — both beautiful dives with about 30min deco that I highly recommend) and they should arrange the day/guide/permits (you need permits for Blue hole area, also technical dives should be “preapproved” by the shop tech manager) and also arranging a pickup/drop off from/to Sharm
Some more options for dive centers that I can personally vouch for on the tek diving front:
- Shams
- Planet Divers
- ScubaSeekers
- H2O divers
- Sly dive
Dive sites in Dahab are mostly “area” reefs that you can take from their rec to technical depths,
Lighthouse is the town center one (and where most OW classes are made; but once you step in deeper it’s quite amazing actually
There is also “The bridge”, this one is close to Lighthouse and is a house reef for training at ScubaSeekers, mostly tech trainings; again once you ramp down things are pretty ; effectively this is just a different entry for lighthouse
Islands is one dive site that isn’t really worth any tech diving, but my favorite reef in dahab, so colorful; it’s part of the Lagoon(a) area
There’s the south trilogy (imagine the blue hole cafe area but in the south side), that has 3 sites: Golden Blocks, Caves, and Three pools; cool reefs over there; surge entry at Caves
Sadly I can’t offer you better quality maps (nor the site descriptions that are in txt) (picture compression on scubaboard) as I have them in book format; but if you google image search for Dahab dive maps you can find bunch of them digitally
LMK of I can help with any details or recommendations
But most almost all sites are pretty in their way, so lot’s of colors to look at while you are on DECO
My vote for <60m (80-120m runtime) dives in Dahab is:
- Arch (Blue hole), I saw a pack of Tuna once we crossed the Arch, and dolphins while exiting from outside the wall (dolphins are more of a summer thing, so low odds) (this dive is the reason I decided to get certified as a OW diver, finally did it last year)
-Canyon, flat slope entry till 15m, cayon hole drops to 32, penetration under the canyon till 47-53m (tide depending depth); exit by the outer wall, watch octopi during deco at the 21-6m depth, you really don’t feel the deco wait the entire dive (my absolute favorite actually, always do it when I am in Dahab)
- Any other spot would work more or less the same, Lighthouse or Goldenblock are the ones I did on a technical level, I can recommend Lighhouse more because it’s an “easier” dive and there’s a practice area (hoops, passages.. at the shallower part) so it can also be a good check dive; on the deeper end it has cool coral structures and even huge Napoleon fish, and if you’re very lucky Rays
