I've tried 3 excursions there. You might consider "Rafting on the Martha Brae" which is scenic, extremely relaxing, and only takes half a day. The bus ride is also only 20 minutes or so. At one point, I avoided it after reading some very negative reviews from guests who had been harassed by angry guides on the rafts after they refused to buy their goods. However, as long as you bring $20 in cash to buy whatever carved coconut they sell, you won't have any problems. I knew it would come up and just considered part of the cost from the time that I booked. At the end of the excursion, they will stop at some church in Falmouth. Our guides hinted to us that we didn't have to stop if we'd rather go back to the ship and, fortunately, everyone in the bus agreed to the latter. If I were to go again, I would approach a few of the other guests and suggest skipping the church. I haven't been there, but I read in reviews that there is very little to see aside from pushy street vendors. With these notes in mind, I would definitely recommend this excursion: the rafting itself takes about an hour and was so quiet and peaceful.
